図4の概略図又は図7の写真に表したような、15mmの内径Di及び外径Deを有する螺旋を、50回/mの撚りで撚った200テックスの3K炭素糸(Tenax製HTA5131)を配置することにより製造する。連続平均二経路間の配置間隔pは0.98mmである。糸は、硬化剤を含有するエポキシ樹脂(Hexcel製E01)で15g/m2に粉末処理したシリコンペーパー上の螺旋に従って配置する。得られた層は0.2mmの厚さを有する。
上記装置に相似の、糸23本の同時配置が可能な装置を用いて、図3の概略表示に図示されるような、ドアコーナー強化用の「撚糸のウェブ」の層を得る。すなわち、角度90°で、内径95mm及び外径475mmを有する円弧を、17回/mの撚りで撚った446テックスの12K炭素糸(Hexcel製IM7−6000)を配置させることにより製造する。連続する糸2本の中央繊維間の間隔である配置間隔は1.65mmである。配置は、表面密度72g/m2のエポキシ樹脂フィルム(Hexcel製Hexply8852)上に行う。
本発明の方法に従って部品を製造し、その機械的性質を他の方法で得た3種の他の部品と比較する。
図9A及び図9Bに表した部品に一致する部品を、一方向ウェブ層及び例1に従って製造した「撚糸のウェブ」の層を、2つの開口部100及び101において繊維配向50/40/10が得られるようにドレープさせることにより製造する。
図11に示した部品に一致する部品を、織物の層を、繊維配向50/40/10が得られるようにドレープさせることにより得る。
■ 織物B(Hexcel E01で10g/m2に粉末処理した、縦糸及び横糸が3K HR炭素糸の205g/m2のタフタ)
■ 織物C(Hexcel E01で2×10g/m2に粉末処理した、縦糸が6K HR炭素糸、横糸がガラスE 34テックスの、290g/m2の一方向タフタ)
図11に示した部品に一致する部品を、一方向ウェブの層を、例3a)に記載したように、シーケンスAを19回重ね合わせることにより、繊維配向50/40/10が得られるようにドレープさせることによって得る。
図9A及び図9Bに表した部品に一致する部品を、2つの開口部100及び101における「撚糸のウェブ」の層を、205g/m2の織物B(タフタ205g/m2、3K HR)E01 2×10g/m2の織物ウェブから切り出した、22mmの内径を有し、図12に示すように外径を変化させた円板で置き換え、例3a)に従い、繊維配向50/40/10が得られるように製造する。
