る。 2. Description of the Related Art A method of manufacturing a ship body is conventionally known in which a woven fabric of reinforcing fibers such as glass fibers and a resin such as polyester are laminated and then integrally molded in a mold.
However, in the conventional method, the woven fabric is pressed against one side of the mold due to the pressure during resin injection, and the resin does not reach the back side of the woven fabric, so injection molding cannot be used. It was virtually impossible. This is because if the woven fabric is lopsided, the desired strength will not be obtained and the appearance will be impaired.
本発明は樹脂の圧力注入に際しても織布の移動
が少なくかつ樹脂を一様に行きわたらせることが
でき、したがつて射出成形法を採用しても前述の
問題が生ぜず強度的に優れた製品を作り得る船体
の製造方法を提供することを目的とする。 In the present invention, even when resin is pressure-injected, the movement of the woven fabric is small and the resin can be uniformly distributed. Therefore, even if the injection molding method is adopted, the above-mentioned problems do not occur and the resin is excellent in strength. The purpose is to provide a method for manufacturing hulls that can be used to manufacture products.

脂製船体の製造方法が提供される。 According to the present invention, a mold having a recess formed in a part is used, and a core material such as a resin is wrapped with a reinforcing fiber body in which a nonwoven fabric of reinforcing fibers is arranged on one side of a woven fabric of reinforcing fibers, and the core material such as resin is inserted into the recess. There is provided a method for manufacturing a fiber-reinforced resin hull, which comprises injecting a resin into the mold after insertion, integrally molding a core material, and forming reinforcing bones by the recesses.
この場合、前記不織布は長繊維のものを使用し

ましい。 In this case, it is preferable that the nonwoven fabric be made of long fibers to ensure resin distribution and strength.
以下図面を参照して本発明の繊維強化樹脂製船
体の製造方法を説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for manufacturing a fiber-reinforced resin hull according to the present invention will be described below with reference to the drawings.

印Ａ方向へ加圧して注入される。 A mold for molding the hull includes a male mold 12 and a female mold 14, the periphery of which can be sealed during molding via a seal 16 made of rubber or the like. An injection hole 18 for injecting the resin in the mold is provided at a desired location of the male mold 12, and the resin is injected under pressure in the direction of arrow A.
雄型１２と雌型１４との間に形成される成形空
間は船体例えばボート等の小型船舶の船体の形状
を有する。 The molding space formed between the male mold 12 and the female mold 14 has the shape of a ship's body, for example, the hull of a small vessel such as a boat.

挾持される。 In the manufacturing method of the present invention, first, a woven fabric 20 made of reinforcing fibers and a nonwoven fabric 22 made of reinforcing fibers positioned in an overlapping relationship on one side of the woven fabric are arranged in the molding space. The peripheries of these woven and non-woven fabrics are clamped by the packing seal 16 at the same time as the mold is sealed.
また、雄型１２の一部には凹み２４が形成され
該凹み内には樹脂等で作つた芯材２６をガラス繊

が好ましい。 Further, a recess 24 is formed in a part of the male die 12, and a core material 26 made of resin or the like wrapped with a nonwoven fabric 28A and a woven fabric 28B made of glass fiber or the like is inserted into the recess. As the core material 26, it is preferable to use a relatively lightweight material such as foamed plastic.
次いで成形型の周辺をクランプして密閉した後
前記注入孔１８を通して樹脂が射出注入して繊維
強化樹脂すなわちFRP製の船体を成形する。 Next, after the periphery of the mold is clamped and sealed, resin is injected through the injection hole 18 to form a hull made of fiber-reinforced resin, that is, FRP.

織布のいずれか片側面に不織布２２の層を設ける
ようにする。 The woven fabric 20 is preferably formed into a single layer, and a layer of nonwoven fabric 22 is provided on either side of the woven fabric.
本発明の樹脂製船体の製造方法は以上述べた要
領で行なわれるので、次のような作用効果が得ら
れる。 Since the method for manufacturing a resin hull of the present invention is carried out in the manner described above, the following effects can be obtained.
先ず、射出成形に際し、織布２０は不織布２２

圧力によつて織布が大きく移動することはない。
また、注入された樹脂は織布２０の織目を通して
浸透し不織布２２内へ入る。該不織布２２内へ浸
出した樹脂は該不織布に沿つて成形型内へ広くか
つ均一に行きわたる。こうして、本発明の樹脂製
船体の製造方法によれば、強化繊維は成形空間内
の所定位置に保持されると同時に樹脂は成形空間
全域に一様に行きわたるので、従来実施化が困難
であつた射出成形法によつても強度及び外観に優
れた安定した品質の船体を成形することができ
る。 First, during injection molding, the woven fabric 20 is replaced with a non-woven fabric 22.
Because the fabric is pressed against one side of the mold, that is, the inner surface of the male die in the case shown, by the elasticity of the fabric, the woven fabric does not move significantly due to the injection pressure of the resin.
Further, the injected resin permeates through the weave of the woven fabric 20 and enters the nonwoven fabric 22. The resin leached into the nonwoven fabric 22 spreads widely and uniformly into the mold along the nonwoven fabric. In this way, according to the method of manufacturing a resin hull of the present invention, the reinforcing fibers are held at a predetermined position within the molding space, and at the same time, the resin is uniformly distributed throughout the entire molding space, which is difficult to implement in the past. It is also possible to mold a hull of stable quality with excellent strength and appearance using the injection molding method.
さらに、型の一部に凹みを形成し該凹み内に繊
維を巻き付けた芯材を挿入しておけば、浮体付き

の芯材としては比較的強度に優れた材質を選ぶべ
きであろう。 Furthermore, by forming a recess in a part of the mold and inserting a core material around which fibers are wound into the recess, it is possible to easily mold a ship body with a floating body. In the case of a floating body, it is preferable to use a material with relatively low specific gravity, such as resin foam, as the core material 26 . In addition,
By providing recesses 24 corresponding to parts of the hull that require reinforcement in the same manner as in the molding of the floating body, a reinforced bone hull can be easily molded. In the case of reinforced bone, a material with relatively high strength should be selected as the core material.

型の数も軽減することができる。 As explained above, according to the method for manufacturing a resin hull of the present invention, it becomes possible to mold a fiber-reinforced resin (FRP) hull by employing an injection molding method that has been virtually impossible to implement in the past. Therefore, not only can productivity be greatly improved, but also FRP hulls of a certain quality with excellent strength and appearance can be manufactured in large quantities. Furthermore, the number of molds required to produce a certain quantity can also be reduced.
