Abstract
Description
これによれば、繊維構造体において、一方の糸の糸主軸方向に沿った最外糸より内側には目止め部を形成しない。このため、目止め部を形成することで発生する強化繊維の蛇行を最小限とすることができる。
これによれば、目止め部では、積層方向に重なり合う糸同士の間で非連続繊維が絡み合うこととなり、繊維が絡み合う箇所を多数形成でき、解れを効果的に抑止できる。
図1に示すように、繊維強化複合材10は、多層織物製の繊維構造体11にマトリックス樹脂Maを含浸させて構成されている。マトリックス樹脂Maとしては、例えば、熱硬化性樹脂のエポキシ樹脂が使用される。繊維構造体11は、織物20を複数積層して構成されている。
繊維構造体11が備える目止め部14により、第1の織端部12及び第2の織端部13の解れが抑止される。
(1)目止め部14は、積層方向に重なり合う糸の強化繊維同士を絡ませて形成されている。よって、別部材を追加することなく第1の織端部12及び第2の織端部13の解れを抑止でき、製造コストが嵩むことを抑制できる。
○ 経糸21及び緯糸31は非連続繊維11aから形成されていなくてもよく、連続繊維が数百〜数万本束ねられて形成された連続糸であってもよい。
○ 繊維構造体40において、積層する緯糸層及び経糸層の数は適宜変更してもよい。
次に、上記実施形態及び別例から把握できる技術的思想について以下に追記する。
