Description

本発明は、繊維強化熱可塑性樹脂成形体の製造方法に関し、とくに、リブ等の立設部分を有する場合にあっても立設部分が容易にかつ確実に所望の形状や強度に成形され得る繊維強化熱可塑性樹脂成形体の製造方法に関する。 The present invention relates to a method for producing a fiber-reinforced thermoplastic resin molded body, and in particular, a fiber that can be easily and surely formed into a desired shape and strength even when it has a standing portion such as a rib. The present invention relates to a method for producing a reinforced thermoplastic resin molded article.

繊維強化熱可塑性樹脂成形体を成形する場合、所望の形状に成形するために、強化繊維と熱可塑性樹脂からなる成形用基材の良好な流動性が求められるが、良好な流動性を得るために、基材を所定枚数以上積層して成形に供する技術が知られている（例えば、特許文献１）。   When molding a fiber reinforced thermoplastic resin molded body, in order to form a desired shape, good fluidity of a molding substrate composed of reinforced fibers and a thermoplastic resin is required, but in order to obtain good fluidity In addition, a technique is known in which a predetermined number of substrates are laminated and used for molding (for example, Patent Document 1).

しかし、とくに成形体がリブ等の立設部分を有する場合には、強化繊維束をリブ形成部分内に充填させることにより成形されるか、もしくはマット状の強化繊維が成形の際にリブ形成部分内に充填されることにより成形される。前者の場合には、例えばプレス成形等が難しい場合が多いので、プレス成形等により成形を行う場合には、通常、不連続な強化繊維がランダムに配置された熱可塑性樹脂基材を成形に用いる。   However, in particular, when the molded body has a standing part such as a rib, it is molded by filling the reinforcing fiber bundle into the rib forming part, or the mat-like reinforcing fiber is formed in the rib forming part during molding. Molded by filling inside. In the former case, for example, press molding or the like is often difficult. Therefore, when molding by press molding or the like, a thermoplastic resin base material in which discontinuous reinforcing fibers are randomly arranged is usually used for molding. .

例えば図５に示すように、成形型１０１内に、ランダムに配置された強化繊維１０２と熱可塑性樹脂からなるマトリックス樹脂１０３とからなる成形用基材１０４が配置され、これを成形型１０１によりプレス成形し、プレス成形時に、リブ形成部１０５内に基材１０４が流動されて充填される。   For example, as shown in FIG. 5, a molding base material 104 composed of reinforcing fibers 102 and a matrix resin 103 made of a thermoplastic resin, which are randomly arranged, is disposed in a molding die 101, and this is pressed by the molding die 101. At the time of molding and press molding, the base material 104 is fluidized and filled in the rib forming portion 105.

ところが、図５に示したような成形方法では、リブ形成部１０５内で望ましくない強化繊維の配向が発生して、強化繊維による強度向上効果が所望の方向に発現されない場合が生じるおそれがある。また、リブ形成部１０５内に強化繊維が十分に充填されなかったり、樹脂リッチな部分が発生したり、強化繊維を含む樹脂が存在しない部分が発生したりするおそれもある。このような部分が発生すると、所定強度のリブの成形が困難になり、場合によっては、所定形状のリブの成形まで困難になる。このような問題の発生を回避するために、プレス圧を極めて高く設定する方法が考えられるが、プレス能力が決まっている成形装置では、そのような方法ではうまく対応できないことがある。   However, in the molding method as shown in FIG. 5, undesirable reinforcement fiber orientation may occur in the rib forming portion 105, and the strength improvement effect by the reinforcement fibers may not be expressed in a desired direction. Further, there is a possibility that the reinforcing fibers are not sufficiently filled in the rib forming portion 105, a resin-rich portion is generated, or a portion where no resin containing the reinforcing fiber is present. When such a portion is generated, it becomes difficult to form a rib having a predetermined strength, and in some cases, it is difficult to form a rib having a predetermined shape. In order to avoid the occurrence of such a problem, a method of setting the press pressure extremely high can be considered, but such a method may not be able to cope with a molding apparatus in which the press capability is determined.

一方、特許文献２には、リブ形成部とその他の形成部分とを予め別の成形型で成形しておき、両者をプレス加工することで一体化する技術が開示されている。しかしこの方法では、それぞれ予め成形された部材がプレス加工により一体化されるので、一体化された両部材の境界部分ではその部分に内在する強化繊維に切れ目や界面が存在しやすくなり、とくにリブ部分の根元部位では強化繊維による十分な補強効果が得られないおそれがある。また、プレス加工前には一旦両部材を予め成形しておくため、プレス加工時に両部材間にわたって素材の比較的大きな流動が生じにくくなり、通常一般の成形体全体をプレス成形して一体成形する場合に発現される成形用素材自体の優れた流動性を利用しにくくなる。そのため、所望の３次元形状への成形を容易に行うことが困難になる場合がある。   On the other hand, Patent Document 2 discloses a technique in which a rib forming portion and other forming portions are formed in advance with different forming dies, and both are integrated by pressing. However, in this method, the preformed members are integrated by pressing, so that the boundary between the two integrated members tends to have breaks and interfaces in the reinforcing fibers present in that portion, especially ribs. There is a possibility that a sufficient reinforcing effect by the reinforcing fiber cannot be obtained at the root portion of the portion. In addition, since both members are once formed in advance before the press working, it is difficult for a relatively large flow of the material to flow between the two members during the press working. Usually, the entire general molded body is press-molded and integrally formed. It becomes difficult to utilize the excellent fluidity of the molding material itself that is manifested in some cases. Therefore, it may be difficult to easily form the desired three-dimensional shape.

そこで本発明の課題は、上記のような従来技術における問題点に着目し、プレス成形におけるプレス圧を適切に抑えつつ、リブ等の立設部分を備えた所望の３次元形状を有する成形体を容易にかつ確実に成形でき、しかも、その立設部分とその他の部分との境界部においても強化繊維による十分な補強効果を発現させて成形体全体として高い機械特性を有する繊維強化熱可塑性樹脂成形体の製造方法を提供することにある。 Accordingly, the object of the present invention is to pay attention to the problems in the prior art as described above, and to provide a molded body having a desired three-dimensional shape having standing portions such as ribs while appropriately suppressing the pressing pressure in press molding. Fiber-reinforced thermoplastic resin molding that can be easily and reliably molded, and that exhibits a sufficient reinforcing effect by reinforcing fibers at the boundary between the standing part and other parts, and has high mechanical properties as a whole. It is in providing the manufacturing method of a body.

上記課題を解決するために、まず、本発明において製造目標とする繊維強化熱可塑性樹脂成形体の基本構成は、プレスによって成形され、面形状形成部分から面外方向に立ち上がる少なくとも一つの立設部分を有する繊維強化熱可塑性樹脂成形体において、該成形体が、強化繊維がランダムに配向された強化繊維層を有する繊維強化熱可塑性樹脂層から構成され、該繊維強化熱可塑性樹脂層の前記強化繊維層が、前記面形状形成部分と前記立設部分の内部との間で連続して延在しているものからなる（第１の繊維強化熱可塑性樹脂成形体と言うこともある）。ここで、強化繊維層を構成する個々の強化繊維は、流動性を良好に保つために、後述の如く所定長さの不連続繊維でよいが、それらによって構成される強化繊維層が、上記面形状形成部分と上記立設部分の内部との間で連続して延在していることが重要である（以下の別の形態においても同じである）。 In order to solve the above problems, first, the basic configuration of a fiber-reinforced thermoplastic resin molded article to Oite production target in the present invention is shaped by press, standing from the surface shape forming part of at least one rise in out-of-plane direction In the fiber reinforced thermoplastic resin molded article having the provided portion, the molded article is composed of a fiber reinforced thermoplastic resin layer having a reinforced fiber layer in which the reinforced fibers are randomly oriented, and the fiber reinforced thermoplastic resin layer reinforcing fiber layers, (sometimes they referred to as a first fiber-reinforced thermoplastic resin molded article) of the surface shape forming portion and the standing continuously between the interior of the provided portion consisting of even that not extend . Here, in order to maintain good fluidity, the individual reinforcing fibers constituting the reinforcing fiber layer may be discontinuous fibers having a predetermined length as will be described later. It is important that it continuously extends between the shape forming portion and the inside of the standing portion (the same applies to other forms described below).

このような第１の繊維強化熱可塑性樹脂成形体においては、成形体を構成する繊維強化熱可塑性樹脂層の強化繊維層が、面形状形成部分と立設部分の内部との間で（つまり、面形状形成部分と立設部分の内部とにわたって）連続して延在しているので、面形状形成部分と立設部分との間に実質的に強化繊維層の境界部が存在せず、この部分も他部分と同様、強化繊維の存在により十分に補強されることになる。したがって、全体として高い機械特性を有する繊維強化熱可塑性樹脂成形体が実現される。 In such a first fiber reinforced thermoplastic resin molded body, the reinforced fiber layer of the fiber reinforced thermoplastic resin layer constituting the molded body is between the surface shape forming portion and the inside of the standing portion (that is, Since it extends continuously (over the surface shape forming portion and the inside of the standing portion), there is substantially no boundary of the reinforcing fiber layer between the surface shape forming portion and the standing portion. Like the other parts, the part is sufficiently reinforced by the presence of the reinforcing fibers. Therefore, a fiber reinforced thermoplastic resin molded article having high mechanical properties as a whole is realized.

上記第１の繊維強化熱可塑性樹脂成形体は、少なくとも２層以上の繊維強化熱可塑性樹脂層の積層構造を有する形態とすることが好ましい。すなわち、複数の繊維強化熱可塑性樹脂層の強化繊維層が、面形状形成部分と立設部分の内部との間で連続して延在している構成とされることにより、立設部分やそれと面形状形成部分との境界部分の、さらには成形体全体としてのより高い機械特性が確保される。 The first fiber-reinforced thermoplastic resin molded body preferably has a laminated structure of at least two or more fiber-reinforced thermoplastic resin layers. That is, the reinforcing fiber layers of the plurality of fiber-reinforced thermoplastic resin layers are configured to continuously extend between the surface shape forming portion and the inside of the standing portion, thereby allowing the standing portion and the Higher mechanical properties of the boundary portion with the surface shape forming portion and further as the entire molded body are ensured.

上記第１の繊維強化熱可塑性樹脂成形体においては、上記強化繊維層を構成する強化繊維としてはとくに限定されず、例えば、炭素繊維、ガラス繊維、アラミド繊維のいずれかから選ばれる１つ以上である形態を採用できる。 In the first fiber-reinforced thermoplastic resin molded body, the reinforcing fiber constituting the reinforcing fiber layer is not particularly limited. For example, the reinforcing fiber layer may be one or more selected from carbon fiber, glass fiber, and aramid fiber. A certain form can be adopted.

また、上記強化繊維層を構成する強化繊維の繊維長としては、例えば１０ｍｍ〜１００ｍｍの範囲にあることが好ましい。このような範囲の繊維長としておくことにより、プレス成形の際の良好な流動性が確保され、強化繊維による優れた補強効果を得つつ、良好な成形性が得られる。   Moreover, as a fiber length of the reinforced fiber which comprises the said reinforced fiber layer, it is preferable to exist in the range of 10 mm-100 mm, for example. By setting the fiber length in such a range, good fluidity at the time of press molding is ensured, and good moldability is obtained while obtaining an excellent reinforcing effect by the reinforcing fibers.

そして、本発明において製造目標とする繊維強化熱可塑性樹脂成形体は、プレスによって成形され、面形状形成部分から面外方向に立ち上がる少なくとも一つの立設部分を有する繊維強化熱可塑性樹脂成形体において、該成形体が、強化繊維がランダムに配向された第１の強化繊維層を有する第１の繊維強化熱可塑性樹脂層と該第１の繊維強化熱可塑性樹脂層の少なくとも片面に積層され第２の強化繊維層を有する第２の繊維強化熱可塑性樹脂層とから構成され、前記立設部分において前記第２の繊維強化熱可塑性樹脂層が破断されているとともに、前記第１の繊維強化熱可塑性樹脂層の前記第１の強化繊維層が、前記面形状形成部分と前記立設部分の内部との間で連続して延在しているものからなる（第２の繊維強化熱可塑性樹脂成形体と言うこともある）。 And, the fiber reinforced thermoplastic resin molded body that is the production target in the present invention is a fiber reinforced thermoplastic resin molded body that is molded by a press and has at least one standing part that rises in the out-of-plane direction from the surface shape forming part. The molded body is laminated on at least one side of a first fiber-reinforced thermoplastic resin layer having a first reinforcing fiber layer in which reinforcing fibers are randomly oriented and the first fiber-reinforced thermoplastic resin layer. A second fiber reinforced thermoplastic resin layer having a reinforced fiber layer, the second fiber reinforced thermoplastic resin layer being broken at the standing portion, and the first fiber reinforced thermoplastic resin. said first reinforcing fiber layers of the layer, the surface shape forming portion and the standing continuously between the interior of the provided portion consisting of even that not extend (the second fiber-reinforced thermoplastic resin molded article When Ukoto also).

すなわち、前述の第１の繊維強化熱可塑性樹脂成形体では、１種の繊維強化熱可塑性樹脂層から構成されていたが、上記本発明において製造目標とする第２の繊維強化熱可塑性樹脂成形体では、その繊維強化熱可塑性樹脂層を第１の強化繊維層を有する第１の繊維強化熱可塑性樹脂層として用い、その上に積層された第２の強化繊維層を有する第２の繊維強化熱可塑性樹脂層を用いて構成され、プレス成形時に立設部分においてその第２の繊維強化熱可塑性樹脂層が破断されて、第１の繊維強化熱可塑性樹脂層の第１の強化繊維層が、面形状形成部分と立設部分の内部との間で（つまり、面形状形成部分と立設部分の内部とにわたって）連続して延在している形態の成形体とされる。換言すれば、第１の繊維強化熱可塑性樹脂層の表面に積層されていた比較的弱い第２の繊維強化熱可塑性樹脂層が立設部分において破断されて、その破断部分を通して、第１の繊維強化熱可塑性樹脂層の第１の強化繊維層が、面形状形成部分と立設部分の内部との間で連続して延在している形態である。このような形態では、第２の繊維強化熱可塑性樹脂層が破断されるまでは、第１、第２の繊維強化熱可塑性樹脂層の積層構成により、最終成形前の所望の形態がより確実に維持され、第２の繊維強化熱可塑性樹脂層が破断されたときに、第１の繊維強化熱可塑性樹脂層がその破断部分を通して容易に立設部分の内部へと流動されることになるので、目標とするプレス成形がより容易に行われ、かつ、破断部分と立設部分の位置が対応しているので、最終成形形状もより容易にかつ正確に目標とする形状に成形されることになる。さらに、第２の繊維強化熱可塑性樹脂層の破断により、第１の繊維強化熱可塑性樹脂層の立設部分の内部への流動も容易化されているので、プレス成形におけるプレス圧の抑制も可能となっている。その結果、所望の３次元形状で所望の補強形態を有する繊維強化熱可塑性樹脂成形体が一層容易にかつ確実に得られることになる。 That is, in the first fiber-reinforced thermoplastic resin molded article described above, one had been constructed from fiber reinforced thermoplastic resin layer, the second fiber-reinforced thermoplastic resin to Oite production target to the present invention In the molded article, the fiber reinforced thermoplastic resin layer is used as the first fiber reinforced thermoplastic resin layer having the first reinforced fiber layer, and the second fiber having the second reinforced fiber layer laminated thereon. The second fiber reinforced thermoplastic resin layer is constituted by using the reinforced thermoplastic resin layer, and the second fiber reinforced thermoplastic resin layer is broken at the standing portion at the time of press molding, so that the first reinforced fiber layer of the first fiber reinforced thermoplastic resin layer is formed. The molded body is configured to continuously extend between the surface shape forming portion and the inside of the standing portion (that is, across the surface shape forming portion and the inside of the standing portion). In other words, the relatively weak second fiber-reinforced thermoplastic resin layer laminated on the surface of the first fiber-reinforced thermoplastic resin layer is broken at the standing portion, and the first fiber passes through the broken portion. The first reinforcing fiber layer of the reinforced thermoplastic resin layer has a form extending continuously between the surface shape forming portion and the inside of the standing portion. In such a form, until the second fiber reinforced thermoplastic resin layer is broken, the desired configuration before final molding is more reliably ensured by the laminated configuration of the first and second fiber reinforced thermoplastic resin layers. Maintained, when the second fiber reinforced thermoplastic resin layer is ruptured, the first fiber reinforced thermoplastic resin layer easily flows into the standing portion through the ruptured portion, Since the target press molding is performed more easily and the positions of the fractured portion and the standing portion correspond to each other, the final molded shape can be molded into the target shape more easily and accurately. . Furthermore, since the flow of the first fiber reinforced thermoplastic resin layer into the standing portion is facilitated by the breakage of the second fiber reinforced thermoplastic resin layer, it is possible to suppress the press pressure in press molding. It has become. As a result, a fiber-reinforced thermoplastic resin molded body having a desired three-dimensional shape and a desired reinforcing form can be obtained more easily and reliably.

上記第２の繊維強化熱可塑性樹脂成形体においては、上記第２の繊維強化熱可塑性樹脂層の引張強度が上記第１の繊維強化熱可塑性樹脂層の引張強度の０．３倍以上１倍未満であることが好ましい。０．３倍未満では、第２の繊維強化熱可塑性樹脂層の破断前の第１、第２の繊維強化熱可塑性樹脂層の積層形態の維持が難しくなるおそれがあり、１倍以上であると、確実に第２の繊維強化熱可塑性樹脂層に所定の破断を発生させることが難しくなるおそれがある。 Upper SL In the second fiber-reinforced thermoplastic resin molded article, 1x 0.3 times the tensile strength of the second fiber-reinforced thermoplastic resin layer of the tensile strength in the first fiber-reinforced thermoplastic resin layer It is preferable that it is less than. If it is less than 0.3 times, it may be difficult to maintain the laminated form of the first and second fiber reinforced thermoplastic resin layers before the breakage of the second fiber reinforced thermoplastic resin layer. There is a risk that it is difficult to reliably generate a predetermined break in the second fiber-reinforced thermoplastic resin layer.

また、上記第２の繊維強化熱可塑性樹脂層の厚みが第１の繊維強化熱可塑性樹脂層の厚みの０．０１倍〜０．５倍の範囲にあることが好ましい。第２の繊維強化熱可塑性樹脂層は、自身の破断前の第１、第２の繊維強化熱可塑性樹脂層の積層形態の維持の役割を担うとともに、第１の繊維強化熱可塑性樹脂層に比べ確実に先に破断することが要求されるので、上記の範囲の厚みが適切である。上記厚みが０．０１倍未満であると、積層形態の維持が難しくなるおそれがあり、０．５倍を超えると、確実に第２の繊維強化熱可塑性樹脂層に所定の破断を発生させることが難しくなるおそれがある。   The thickness of the second fiber reinforced thermoplastic resin layer is preferably in the range of 0.01 to 0.5 times the thickness of the first fiber reinforced thermoplastic resin layer. The second fiber reinforced thermoplastic resin layer plays a role of maintaining the laminated form of the first and second fiber reinforced thermoplastic resin layers before breaking itself, and compared with the first fiber reinforced thermoplastic resin layer. Since it is required to surely break first, the thickness in the above range is appropriate. If the thickness is less than 0.01 times, it may be difficult to maintain the laminated form. If the thickness exceeds 0.5 times, the second fiber reinforced thermoplastic resin layer may surely generate a predetermined breakage. May become difficult.

また、この第２の繊維強化熱可塑性樹脂成形体においても、上記第２の強化繊維層を構成する強化繊維としてはとくに限定されず、例えば、炭素繊維、ガラス繊維、アラミド繊維のいずれかから選ばれる１つ以上である形態を採用できる。   In the second fiber reinforced thermoplastic resin molded body, the reinforcing fiber constituting the second reinforcing fiber layer is not particularly limited, and may be selected from, for example, carbon fiber, glass fiber, and aramid fiber. One or more forms can be employed.

また、前述の第１の繊維強化熱可塑性樹脂成形体と同様、上記第１の強化繊維層を構成する強化繊維の繊維長としては、例えば１０ｍｍ〜１００ｍｍの範囲にあることが好ましい。このような範囲の繊維長としておくことにより、プレス成形の際の立設部分内への良好な流動性が確保され、強化繊維による優れた補強効果を得つつ、良好な成形性が得られる。   Further, like the first fiber-reinforced thermoplastic resin molded body, the fiber length of the reinforcing fibers constituting the first reinforcing fiber layer is preferably in the range of 10 mm to 100 mm, for example. By setting the fiber length in such a range, good fluidity into the standing portion at the time of press molding is ensured, and good moldability is obtained while obtaining an excellent reinforcing effect by the reinforcing fibers.

また、上記第２の強化繊維層を構成する強化繊維の繊維長についても、０．１ｍｍ〜１００ｍｍの範囲にあることが好ましい。このような範囲の繊維長としておくことにより、全体として円滑な成形が可能になる。   Further, the fiber length of the reinforcing fibers constituting the second reinforcing fiber layer is preferably in the range of 0.1 mm to 100 mm. By setting the fiber length within such a range, smooth molding as a whole becomes possible.

上記のような第１の繊維強化熱可塑性樹脂成形体は、次のような方法によって製造できる。すなわち、第１の繊維強化熱可塑性樹脂成形体の製造方法は、面形状形成部分から面外方向に立ち上がる少なくとも一つの立設部分を有する繊維強化熱可塑性樹脂成形体をプレスによって成形する繊維強化熱可塑性樹脂成形体の製造方法において、強化繊維がランダムに配向された強化繊維層を有する繊維強化熱可塑性樹脂層を、下型と昇降可能な上型とからなるプレス成形型内に配置するとともに加熱溶融させ、しかる後に、前記上型を下降させて、前記繊維強化熱可塑性樹脂層の前記強化繊維層が前記面形状形成部分と前記立設部分の内部との間で連続して延在するようにプレス成形を行う方法からなる。 The first fiber-reinforced thermoplastic resin molded body as described above can be manufactured by the following method. That is, the first method for producing a fiber reinforced thermoplastic resin molded article is a fiber reinforced heat molding process in which a fiber reinforced thermoplastic resin molded article having at least one standing part rising from the surface shape forming part in the out-of-plane direction is formed by pressing. In the method for producing a plastic resin molded body, a fiber-reinforced thermoplastic resin layer having a reinforcing fiber layer in which reinforcing fibers are randomly oriented is placed in a press mold composed of a lower mold and an upper mold that can be raised and lowered and heated. After melting, the upper mold is lowered so that the reinforcing fiber layer of the fiber reinforced thermoplastic resin layer continuously extends between the surface shape forming portion and the inside of the standing portion. ing from the line cormorant way method press molding to.

また、上記第２の繊維強化熱可塑性樹脂成形体は、次のような本発明に係る方法によって製造できる。すなわち、本発明に係る繊維強化熱可塑性樹脂成形体の製造方法は、面形状形成部分から面外方向に立ち上がる少なくとも一つの立設部分を有する繊維強化熱可塑性樹脂成形体をプレスによって成形する繊維強化熱可塑性樹脂成形体の製造方法において、繊維長が１０ｍｍ〜１００ｍｍである強化繊維がランダムに配向された第１の強化繊維層を有する第１の繊維強化熱可塑性樹脂層と該第１の繊維強化熱可塑性樹脂層の少なくとも片面に積層され第２の強化繊維層を有する第２の繊維強化熱可塑性樹脂層とを、下型と昇降可能な上型とからなるプレス成形型内に配置するとともに加熱溶融させ、しかる後に、前記上型を下降させて、前記立設部分において前記第２の繊維強化熱可塑性樹脂層が破断され、かつ、前記第１の繊維強化熱可塑性樹脂層の前記第１の強化繊維層が前記面形状形成部分と前記立設部分の内部との間で連続して延在するようにプレス成形を行うことを特徴とする方法からなる。 The second fiber-reinforced thermoplastic resin molded body can be produced by the following method according to the present invention. That is, the method for producing a fiber-reinforced thermoplastic resin molded body according to the present invention is a fiber reinforced thermoplastic resin molded body having a fiber-reinforced thermoplastic resin molded body having at least one standing part rising in an out-of-plane direction from a surface shape forming part. In the method for producing a thermoplastic resin molded body, a first fiber-reinforced thermoplastic resin layer having a first reinforcing fiber layer in which reinforcing fibers having a fiber length of 10 mm to 100 mm are randomly oriented and the first fiber reinforcement A second fiber-reinforced thermoplastic resin layer having a second reinforcing fiber layer laminated on at least one surface of the thermoplastic resin layer is placed in a press mold composed of a lower mold and an upper mold that can be raised and lowered and heated. Then, the upper mold is lowered, the second fiber reinforced thermoplastic resin layer is broken at the standing portion, and the first fiber reinforced thermoplastic is melted. The fat layer first reinforcing fiber layer is made of a method which is characterized in that a continuous press forming so as to extend between the inside of the standing portion component and the surface shape forming portion.

このように、本発明に係る繊維強化熱可塑性樹脂成形体の製造方法によれば、リブ等の立設部分を備えた３次元形状を有する成形体を、その立設部分とその他の部分との境界部においても強化繊維による十分な補強効果を発現させて成形体全体として高い機械特性を有する繊維強化熱可塑性樹脂成形体として容易に成形できる。 Thus, according to the method for producing a fiber-reinforced thermoplastic resin molded article according to the present invention, a molded article having a three-dimensional shape with vertical portions of the ribs, etc., with its vertical portions and the other portions Even at the boundary portion, a sufficient reinforcing effect by the reinforcing fibers can be expressed and the molded body can be easily molded as a fiber reinforced thermoplastic resin molded body having high mechanical properties as a whole.
