Abstract
Description
図1は、本実施形態に係る引抜成形品の製造装置1の一例を模式的に示す図である。製造装置1は、強化繊維に熱硬化性樹脂が含浸された中間成形品Sを引抜成形することによって、引抜成形品Mを製造する。
図3は、本実施形態に係る成形型60を模式的に示す断面図であり、図1のA-A線断面矢視図に相当する。図4は、本実施形態に係る成形型60を模式的に示す断面図であり、図1のB-B線断面矢視図に相当する。
次に、本実施形態に係る引抜成形品Mの製造方法の一例について説明する。図5は、本実施形態に係る引抜成形品Mの製造方法の一例を示すフローチャートである。図6は、本実施形態に係る中間成形品Sの一部を模式的に示す図である。
以上説明したように、本実施形態によれば、中間成形品Sを加熱硬化するための成形型60が弾性変形可能な袋体100を有するため、成形型60に導入される中間成形品Sの厚みが変化したとき、中間成形品Sの厚みの変化に応じて、袋体100は弾性変形する。これにより、厚みが厚い中間成形品Sが成形型60に導入された場合、中間成形品Sに過度な応力が作用することが抑制される。また、厚みが薄い中間成形品Sが成形型60に導入された場合、中間成形品Sに対する加圧が不足することが抑制される。したがって、成形型60に導入される中間成形品Sの厚みが変化しても、製造される引抜成形品Mの品質の低下が抑制される。
なお、上述の実施形態においては、中間成形品Sの第1プレート部310及び第2プレート部320のそれぞれが、2つの袋体100で挟まれることとした。図7に示すように、第1プレート部310が2つの袋体100で挟まれ、第2プレート部320が袋体100とハウジング63の内面との間に挟まれてもよい。図7は、第1プレート部310が袋体101と袋体102とに挟まれ、第2プレート部320の一部が袋体101とハウジング63とに挟まれ、第2プレート部320の一部が袋体102とハウジング63とに挟まれる例を示す。また、ハウジング63の内面には、強化繊維シートFbと接触するように整形部材180が設けられる。
