Abstract
Description
貯留槽内で、図13に示すように、バサルト繊維を上流側に位置する二つの丸棒体に圧接させるようにすれば、バサルト繊維の扁平状態への圧し拡げをより効果的に行うことができる。なお、圧接部材は必ずしも丸棒体で構成する必要はなく、また棒体である必要もない。
Claims (7)
- 強化繊維材内に熱可塑性樹脂材が含浸されて一体化した筋金棒体を製造する方法であって、液状の熱可塑性樹脂材が貯留された貯留槽内に非扁平な束状の前記強化繊維材を通過させるとともに、通過する前記非扁平な束状の強化繊維材を貯留槽内で扁平状態に圧し拡げて当該強化繊維材間に熱可塑性樹脂材を浸透させ、熱可塑性樹脂材が浸透した扁平な強化繊維材を再び非扁平な束状に収束成形したことを特徴とする筋金棒体の製造方法。
- 前記貯留槽内に複数の棒体を横設して、前記束状の強化繊維材をこれら棒体の間に圧接状態で懸架し通過させることによって当該強化繊維材を扁平状態に圧し拡げるようにした請求項1に記載の筋金棒体の製造方法。
- 収束成形された前記強化繊維材の外周を他の熱可塑性樹脂材により所定の締め付け力で被覆した請求項1に記載の筋金棒体の製造方法。
- 前記収束成形した強化繊維材の外周に前記他の熱可塑性樹脂材の所定幅のフィルム材を所定の締め付け力で巻いて被覆した請求項3に記載の筋金棒体の製造方法。
- 前記他の熱可塑性樹脂材による被覆前に、前記収束成形された強化繊維材の外周の少なくとも一カ所に、当該強化繊維材の長手方向へ延びる、引張強度に優れた長尺体を一体的に溶着させた請求項3又は4に記載の筋金棒体の製造方法。
- 前記長尺体として糸状体を使用した請求項5に記載の筋金棒体の製造方法。
- 前記他の熱可塑性樹脂材によって被覆した前記強化繊維材の端部に連結具を溶着した請求項3ないし7のいずれかに記載の筋金棒体の製造方法。
