라켓프레임의 제조방법Racket frame manufacturing method

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음This content is subject to disclosure, so the full text is not included.

제1도는 종래의 제조 방법으로 된 라켓프레임의 부분적단면구조를 보인 입체도이고,1 is a three-dimensional view showing a partial cross-sectional structure of a racket frame using a conventional manufacturing method,

제2 및 3도는 각각 제1도의 단면 구조된 프레임에 외력 또는 가공에 의해서 받는 영향을 도시한 측단면도 이고,Figures 2 and 3 are side cross-sectional views showing the effects of external force or processing on the cross-sectional structured frame of Figure 1, respectively,

제4도는 본 발명의 실시예에 관한 배드민턴의 라켓 프레임을 성형한 금형과 대응하는 프레임 각부를 도시한 국부(局部) 절결 입체도이고,4 is a local cut-out three-dimensional view showing a mold for molding a badminton racket frame according to an embodiment of the present invention and corresponding frame parts,

제5 및 6도는 각기 제4도에 도시된 A-A'선과 B-B'선의 단면도.5 and 6 are cross-sectional views of lines A-A' and B-B', respectively, shown in FIG. 4;

제7 및 8도는 각기 본 발명의 완성품의 단면도이다.7 and 8 are cross-sectional views of the finished product of the present invention, respectively.

Claims (1)

유리섬유, 카본 섬유를 단독 또는 혼합해서 포상으로 직조하여 고분자 에폭시 수지 등의 플라스틱을 함침시켜서 된 함침물 시이트(FRP 또는 CFRP prepreg sheet)를 중공의 관상으로 감던지 혹은 그 섬유를 단독 또는 혼합해서 중공의 관상으로 엮어서 고분자 에폭시 수지등의 플라스틱을 함침시켜서 함침물 튜우브로 하는 공정과 그 관상 함침물의 중공부에 고체의 열가소성 플라스틱과 발포제를 혼합해서 봉상으로 성형된 고형분자 독립 발포재를 장전해서 프레임재 기초로 하는 공정과 그 기초를 링프레임과 슬로오트부와 샤프트와 손잡이로 된 각 구성부분을 일체로 한 금형내에서 동시에 가열성형과 연화발포를 시키는 공정으로 되고 그 섬유보강 플라스틱의 외광층과 발포체심부가 일체로 유착결합해서 되는 프레임에 의해서 각 부분이 구성되고 그 샤프트 부분의 단면 형상이 극단으로 가늘게 되는 배드민턴 라켓등에 있어서는 직경 약 1mmø정도의 연속되는 발포체심부를 형성하는 것을 특징으로 하는 라켓프레임의 제조방법.Glass fiber and carbon fiber alone or mixed and woven into a fabric, impregnated with plastics such as polymer epoxy resin, impregnated sheet (FRP or CFRP prepreg sheet) into a hollow tubular shape, or the fibers alone or mixed to be hollow The process of making an impregnated tube by impregnating plastic such as polymeric epoxy resin by woven into a tubular shape of the tubular impregnation, and a frame material by loading a solid molecular independent foaming material molded into a rod by mixing a solid thermoplastic plastic and a foaming agent in the hollow of the tubular impregnation The base process and the base is a process of simultaneously heating molding and softening foaming in a mold in which each constituent part of the ring frame, slot part, shaft and handle is integrated, and the external light layer and foam of the fiber-reinforced plastic In a badminton racket, where each part is constituted by a frame in which the core part is integrally bonded and the cross-sectional shape of the shaft part is extremely thin, a continuous foam core part with a diameter of about 1mmø is formed.
