Abstract
Description
積層体のz軸補強のために、複合積層体に固定性のない補強繊維を挿入する方法は、z軸繊維の配置材料を必要とする。頂部プレートと底部プレートとの間の、x−y軸材料が送り込まれるチャンバに側部プレートが形成される。チャンバの側部プレートは、x−y軸材料の縁を制限する。複数のz軸繊維が、同時にx−y軸材料内に配置され得るような、複数の側方に間隔を空けたz軸繊維配置機が存在する。この各々は、頂部プレートと底部プレートにそれぞれ独自の開口部を有し、そして、これらは、整列している。底部プレート内の各開口部の下には、テーパ付けされた前先端部を有する、細長の固体ロッドがある。このロッドは、「通路配置プローブ(PDP)」として知られる。PDPは、モータにより回転され、次いで、底部プレート内の開口部、x−y軸材料、そして頂部プレート内の開口部を通って上向きに動かされる。頂部プレート内の開口部の各々の上には、可動性の中空管が設置され、この最初の位置では、その底端部が頂部プレート内の開口部内にわずかに挿入されている。z軸繊維束が、静置されたロールに収容され、そして、この束は、このロールから連続的に自由に引き出される。z軸繊維束の各々の前端部は、可動性の中空管の1つを通って下向きに、その底端部に隣接する位置まで通される。新しい長さが必要になると、可動性の中空管の各々に、規定の長さのz軸繊維束を再供給するための構造体が存在する。
ここで、図面の図1〜6を参照して、複合積層体にz軸補強繊維を挿入する方法が説明される。
一旦、せん断プレート25が、繊維束7から配置されたz軸繊維を切断すると、繊維束7の端部は、内側管16の下方にわずかに伸ばされる。次に、繊維クランプ12Aが解放され、そして繊維クランプ12Bが起動されて、クランプされる。内側管16は、繊維束7の端部が図1に示される位置と同じ相対位置にくるまで、図1に示されるように、z軸方向で上方にさらに起動される。次に、クランプ12Aが起動されてクランプされ、そしてクランプ12Bが解放され、クランプを解除される。これに続いて、内側管16が、図1に示される位置まで、z軸方向で下方に動かされ、これによって、可動内側管16の端部と繊維束7の端部との相対位置が、図1に示されるような位置になる。このサイクルは、ここで、繰り返されるように設定される。
