【発明の詳細な説明】 補強プラスティック材料の製品の製造方法本発明は押圧加工によって熱可塑性シ ートから補強プラスティック材料の製品を製造する方法に関する。[Detailed description of the invention] Method for manufacturing products made of reinforced plastic materials The present invention is a method for manufacturing products made of reinforced plastic materials. The present invention relates to a method for producing products of reinforced plastic material from sheets.

補強プラスティック材料の製品は、先ず最初にシートを軟化温度に加熱し、然る 後にシートをモールド内に移動して先ずプレスを行い、次にモールドの内部で硬 化させることによってシートから製造することができる。強力な押圧力および固 いモールドを必要とする補強シートの成形には大きな成形圧力が要求されるので ある。補強プラスティック材料の大きな部片の製造は特に大きい設備を含み、従 って１つの部片当りの過大な製造費用を回避するために広範囲な一連の製造工程 が要求されるのである。Products made of reinforced plastic materials are manufactured by first heating the sheet to a softening temperature and then Afterwards, the sheet is moved into the mold and first pressed, then hardened inside the mold. It can be manufactured from a sheet by converting it into a sheet. Strong pressing force and firmness The molding of reinforcing sheets requires a large mold, so a large molding pressure is required. be. The manufacture of large pieces of reinforced plastic material involves particularly large equipment and Extensive series of manufacturing steps to avoid excessive manufacturing costs per piece is required.

非繊維性プラスティックシートは例えば真空成形技術によって低い成形圧力で成 形することかできるが、このようなシートから作られた製品の強度は小さい。Non-fibrous plastic sheets can be formed at low molding pressures, for example by vacuum forming technology. Although it can be shaped, the strength of products made from such sheets is low.

本発明の目的は、従来よりも低い成形圧力でシートから補強プラスティック材料 の製品を成形する方法を提供することである。従って、そのための工具の費用は 減少され、時によって要求される試験成形は少ない費用で迅速に製造されること ができるのである。The object of the present invention is to produce reinforced plastic materials from sheets with a lower molding pressure than before. The object of the present invention is to provide a method for molding products. Therefore, the cost of tools for this is Reduced and sometimes required test moldings can be produced quickly and at low cost This is possible.

本発明によって、６０重量？６から９０重量９６の熱可塑性材料（ｔｈｅｒｍｏ ｐｌａｓｔ　）および１０重量％から４０重量９６、望ましくは２０重量％から ３ｏ重量％で、１３μｍの直径を有し、長さか６から１６ｍｍの補強繊維を含む 補強プラスティック材料のシートであって、補強繊維か前記シート内に分散され るようになされている前記補強プラスティック材料のシートが成形され、然る後 にこのシートかモールド内に移動されて、このモールド内でＩＭＰａ、望ましく は０．６ＭＰａよりも低い成形圧力で形成／財形されるのである。According to the present invention, 60 weight? 6 to 90 weight 96 thermoplastic materials (thermo plast　) and from 10% by weight to 40% by weight96, preferably from 20% by weight 30% by weight, containing reinforcing fibers with a diameter of 13 μm and a length of 6 to 16 mm. a sheet of reinforced plastic material, wherein reinforcing fibers are dispersed within said sheet; The sheet of reinforced plastic material adapted to This sheet is then moved into a mold, and within this mold IMPa, preferably is formed/shaped at a molding pressure lower than 0.6 MPa.

シートが大気圧以下の圧力（ｕｎｄｅｒｐｒｅｓｓｕｒｅ　）で多孔性モールド 内で成形されるのが望ましい本発明の方法は、適当な費用で、成る部分は薄く、 他の部分は厚（、また大なる表面の平滑性に加えて、大なる強度および剛性を要 求されるような大きい部片を製造できる能力を与えるものである。The sheet is molded into a porous mold under pressure The method of the present invention, which is preferably formed in Other parts require greater strength and stiffness in addition to greater thickness (and greater surface smoothness). This provides the ability to produce large pieces as required.

本発明の方法に使用される繊維補強シートは英国特許第１１２９７５７号および 第１３２９４０９号に記載されている方法によって形成されるのが望ましいが、 この方法は繊維の甚だ均一な分散を与えるものである。しかしこのようなシート を他の従来技術の湿式または乾燥成形方法によって製造することも可能である。The fiber reinforced sheet used in the method of the present invention is disclosed in British Patent No. 1129757 and No. 1,329,409, preferably formed by the method described in This method provides a very uniform distribution of fibers. But a sheet like this It is also possible to produce by other conventional wet or dry molding methods.

シートの製造方法の如何に拘わらず、繊維材料はシート内で分散されて、それぞ れ単一の別々の繊維の形態になされなければならない。Regardless of how the sheet is manufactured, the fibrous materials are dispersed within the sheet and each must be in the form of a single, separate fiber.

例えば、鉱物性および炭素繊維はこの目的に好適てあ個々の繊維は６ｍｍよりも 短くてはいけない。何故ならばこれよりも短い繊維は製品中に充分な補強作用を 与えないからである。またこれらの繊維は１６ｍｍよりも長くてはいけない、何 故ならばこれよりも長い繊維は適当に分散せず、従って製品を補強しないからで ある。For example, mineral and carbon fibers are suitable for this purpose; the individual fibers are larger than 6 mm. It can't be too short. This is because fibers shorter than this have sufficient reinforcing effect in the product. Because you don't give. Also, these fibers must not be longer than 16mm, no Therefore, fibers longer than this will not disperse properly and therefore will not strengthen the product. be.

繊維は直径が７μｍよりも小さくてはいけない。何故ならば７μｍよりも小さい 直径の繊維は成形された製品に適当な補強を与えないからである。またこれらの 繊維は直径が１３μｍよりも大きくてはいけない。何故ならばこれよりも大きい 繊維は充分平滑な表面を与えないからである。The fibers should not be smaller than 7 μm in diameter. Because it is smaller than 7μm This is because the diameter fibers do not provide adequate reinforcement to the molded product. Also these The fibers should not be larger than 13 μm in diameter. Because it's bigger than this This is because fibers do not provide a sufficiently smooth surface.

長さが平均１２ｍｍで、直径がｌｌＡｔｍのガラス繊維を使用するのが望ましい 。It is preferable to use glass fibers with an average length of 12 mm and a diameter of 11 Atm. .

プラスティック材料の比率は６０重量％よりも少なくてはいけない。何故ならば これよりも少ない比率のプラスティック材料は繊維間間隙を充分に充填すること がなく、多孔性構造を生じさせるからである。またプラスティック材料の比率は ９０重量％よりもおおきくてはいけない。何故ならばこれよりも大きい比率は充 分な量の補強繊維を含まないからである。The proportion of plastic material must not be less than 60% by weight. because Plastic materials with a smaller proportion than this should sufficiently fill the interfiber spaces. This is because there is no porosity, resulting in a porous structure. Also, the proportion of plastic materials is It must not be greater than 90% by weight. This is because a ratio larger than this is This is because it does not contain a sufficient amount of reinforcing fiber.

適当なプラスティック材料は、例えばポリエチレン、ポリプロピレン、ポリ酢酸 ビニル、ポリ塩化ビニルまたはその他の若干の熱可塑性材料である。Suitable plastic materials include, for example, polyethylene, polypropylene, polyacetic acid. Vinyl, polyvinyl chloride or some other thermoplastic material.

シートの構造は一体的に固められないで（ｕｎｃｏｎｓｏｌｉｄａｔｅｄ）　、 透過性を有し、これによってこの構造体を通過する加熱空気によって加熱できる ようになされるか、または部分的または全体的に一体的に固められるようになす ことができるが、この場合にはシートは例えば赤外線加熱方法によって加熱され るのである。The structure of the sheet is unconsolidated, Permeable so that it can be heated by heated air passing through the structure made so as to be solidified in one piece or partially or wholly but in this case the sheet is heated, for example by an infrared heating method. It is.

It is.

第１図は内部に分散されたガラス繊維を存し、それ自体公知の方法で熱および圧 力によって一体的に固められた熱可塑性材料より成るシート１を示している。FIG. 1 has glass fibers dispersed therein and is heated and pressed in a manner known per se. 1 shows a sheet 1 of thermoplastic material consolidated together by force.

このシートｌは赤外線炉２内に移送され、この中でシートは放射装置またはラジ ェーター３によって成形温度まで加熱されて、ガラス繊維の内部応力によって、 シートの直径か大きくなるまで（第１ｂ図）膨張（ｅｘｐａｎｄ）されるのであ る。This sheet l is transferred into an infrared furnace 2, in which the sheet is It is heated to the molding temperature by the water heater 3, and due to the internal stress of the glass fiber, The sheet is expanded until its diameter increases (Figure 1b). Ru.

第１Ｃ図はこのシートを覆うようにシートｌの上に障壁層（ｂａｒｒｉｅｒ　１ ａｙｅｒ　）を附与するところを示している。FIG. 1C shows a barrier layer (barrier 1) on top of sheet l to cover this sheet. ayer) is shown.

このようにして覆っている障壁層を有する完全に柔らかな弾性的なシートは、次 に真空モールド５内に入れられ、このモールド内で、モールドを通って伸長して いる導管６（第１ｄ図）を通って与えられる吸引作用によってモールドの表面に 緊密に圧着されるようになされる。A completely soft elastic sheet with an overlying barrier layer is thus is placed in a vacuum mold 5, within which it is extended through the mold. on the surface of the mold by the suction applied through the conduit 6 (Fig. 1d). Made to be tightly crimped.

この障壁層は空気がシートを通って吸引されるのを阻止し、これによって所望の 圧力差を保持するのを容易になすのである。硬化した時にシートはモールドから 取出される。This barrier layer prevents air from being drawn through the sheet, thereby achieving the desired This makes it easier to maintain a pressure difference. The sheet is removed from the mold when cured. taken out.

第２図に示される本発明の変形実施例においては、成形温度まで加熱されたシー トｌは、上方部分８および下方部分５を存するモールド内て押圧加工される。こ の成形圧力はモールドの下方部分の導管６を通る吸引作用によって与えられ、こ の場合モールドの上方部分はシートを通って空気か吸引されるのを阻止する。大 気圧よりも低い圧力よりも高い成形圧力がモールドの上方部分をモールドの下方 部分に対して押圧することによって形成されるのである。In an alternative embodiment of the invention shown in FIG. The mold is pressed into a mold which has an upper part 8 and a lower part 5. child The molding pressure of is provided by suction through the conduit 6 in the lower part of the mold; In this case the upper part of the mold prevents air from being drawn through the sheet. Big The molding pressure is higher than the pressure lower than the atmospheric pressure and the upper part of the mold is lower than the lower part of the mold. It is formed by pressing against the part.

第３図に示される実施例においては、障壁層または圧力ベル１０の弾性層４が上 面に配置されるようになされたシートｌが、この障壁層または弾性層を介して圧 力ベル内にある過圧によってモールドの下方部分５に対して押圧されるようにな っている。In the embodiment shown in FIG. 3, the barrier layer or elastic layer 4 of the pressure bell 10 is A sheet l adapted to be placed on a surface is pressed through this barrier layer or elastic layer. The overpressure in the force bell causes it to be pressed against the lower part 5 of the mold. ing.

第４図に示された変形形態においては、障壁層または圧力ベル１０の弾性層４が 上面に配置されるようになされたシート１かこの障壁層によって圧力ベル内にあ る例えば０．５ＭＰａの過圧により、またモールドの下方部分の下方の吸引ドー ムｌｌ内の例えば０．０７ＭＰａの大気圧以下の圧力によってモールドの「呼吸 」する下方部分（“ｂｒｅａｔｈｉｎｇ″ｌｏｗｅｒ　５ｅｃｔｉｏｎ　）に対 して押圧されるようになっている。モールド５は金属、例えばアルミニウムによ って作られて、多孔性になされている。モールドの多孔性のために、著しく均一 な吸引作用が得られるのである。In the variant shown in FIG. 4, the barrier layer or elastic layer 4 of the pressure bell 10 is Sheet 1 adapted to be placed on top or inside the pressure bell by means of this barrier layer. Due to the overpressure of e.g. The pressure inside the mold, for example 0.07 MPa below atmospheric pressure, causes the mold to "breathe". ” for the lower part (“breathing” lower 5ection) It is now being pushed. The mold 5 is made of metal, for example aluminum. It is made of porous material. Remarkably uniform due to the porosity of the mold This provides a suction effect.

第２図および第３図に示される実施例においては、シートの形成は単に上方側か らの成形力または過圧により行われることかでき、また第４図の実施例において は圧力ベルを有しないで、単に大気圧以下の圧力によって行われることができる のである。In the embodiment shown in FIGS. 2 and 3, the formation of the sheet is simply from the upper side. The forming force or overpressure of can be carried out without a pressure bell, simply by subatmospheric pressure It is.
