Description

에폭시 수지제 테니스 라켓Epoxy Resin Tennis Racket

제1도는 본 고안의 일부 파절사시도.1 is a partially broken perspective view of the present invention.

제2도는 제1도의 가-가'선 확대단면도.2 is an enlarged cross-sectional view of FIG.

제3도는 본 고안의 구성층을 보인 일부 확대도이다.3 is a partially enlarged view showing the constituent layers of the present invention.

본 고안은 탄력성이 크고 질기면서 변형이 없는 유리섬유로 제직된 테이프상 포지에 에폭시 수지액을 흡침하에 라켓형상으로 성형된 심재표면에 균등히 권착하여 경화시키고, 최종 표면에 에폭시 수지액을 외면이 평활하게 도포하여 완전 경화시켜 얻어지는 테니스 라켓에 관한 것이다.The present invention is hardened by uniformly wound on the surface of the core formed in the racket shape under the absorption of the epoxy resin liquid on the tape-shaped paper fabric made of glass fiber woven with elasticity and toughness without deformation. It relates to a tennis racket obtained by applying smoothly and completely cured.

종래에도 여러 가지 제질의 테니스 라켓트가 고안되어 사용된바 있으나, 에폭시수지를 주재로하여 만들어진 것은 없었고, 목제나 금속제가 대부분이었기 때문에 변형이 많고 제질자체의 강점을 오래 간직하지 않는등 단점이 있었던 것인데, 본 고안은 위와같은 종래의 불편을 시정하기 위하여 안출한 것으로 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Conventionally, various tennis rackets of various materials have been devised and used, but none were made mainly of epoxy resins, and most of them were made of wood or metal, which had many disadvantages such as many deformations and lack of strength of materials. If the present invention is described in detail based on the accompanying drawings to devise to correct the above conventional inconveniences as follows.

합성수지(P.V.C나 P.V.E수지등)를 사용하여 라켓형태로 성형한 중공 심재(1)표면에 에폭시 수지액을 홉침시킨 테이프상의 유리섬유 직포(2)를 소정의 두께가 되도록 다중으로 균등히 권착하여 경화시키고, 이를 완성형틀속에 삽입한후 표면전체에 외면이 평활하도록 일정한 두께의 수지(3)를 피복하여서 일체가 되게 경화시킨 구조이다.Tape-shaped glass fiber woven fabric (2), which is made of synthetic resin (PVC or PVE resin, etc.) in a racket-shaped hollow core material (1), which is doped with epoxy resin liquid, is evenly wound in multiples to a predetermined thickness and cured. After inserting it into the finished mold, the entire surface is coated with a resin 3 having a certain thickness so as to smooth the outer surface thereof, and then hardened to be integral.

이와같이된 본 고안은 에폭시 수지액을 유리섬유 직포(2)에 흡침하여 이를 심재외면에 다중으로 권착경화시킨후 표면에 다시 에폭시 수지 피복층(3)을 섬성했기에 경화되면 완전한 일체가 되어 형태의 변형이 없고 내구적이며, 에폭시 수지특유의 충격완화 작용이 있어 라켓트로서의 기능이 원등한 장점이 있는 것이다.In this way, the present invention was made by absorbing the epoxy resin liquid into the glass fiber woven fabric (2) and wound and hardening it on the outer surface of the core material in multiple layers. It is durable, and has a shock-absorbing effect peculiar to epoxy resins, so that it functions as a racket.

Claims (1)

도면에 표시한 것과 같이 라켓트형상태의 중공심재(1) 외면에 에폭시 수지액을 흡침시킨 테이프상의 유리섬유 직포(2)를 다중으로 적층되게 권착하여 경화시키고 표면에 다시 일정한 두께가 되도록 에폭시 수지액(3)을 피복하여 일체로 경화시킨 에폭시 수지제 테니스 라켓.As shown in the figure, the glass fiber woven fabric (2) on the outer surface of the hollow core material (1) in the racket-shaped state was absorbed and laminated in multiple layers so as to be laminated and cured. (3) An epoxy resin tennis racket coated and cured integrally.
