Description
実施形態1に係る成形治具及び成形方法は、平板形状となる積層体を三次元形状に折り曲げて成形するものである。先ず、図1を参照して、成形後の三次元形状となる積層体1について説明する。
図1は、実施形態1に係る成形治具により成形される積層体を模式的に表した図である。図1に示すように、積層体1は、強化繊維シートを複数積層したものとなっている。積層体1は、長手方向(図1の前後方向)に延在して成形されている。なお、図1において、積層体1の長手方向は、図1の前後方向となっており、積層体1の幅方向は、図1の左右方向となっており、積層体1の高さ方向は、図1の上下方向となっている。そして、長手方向、幅方向及び高さ方向は、相互に直交する方向となっている。
次に、図2から図4を参照して、図1の積層体1を成形するための成形治具10について説明する。図2は、実施形態1に係る成形治具を側面から見たときの模式図である。図3は、実施形態1に係る成形治具を正面から見たときの模式図である。図4は、実施形態1に係る成形治具の雌型を平面から見たときの模式図である。
次に、図7を参照して、実施形態2に係る成形治具10を用いた成形方法について説明する。なお、実施形態2では、重複した記載を避けるべく、実施形態1と異なる部分について説明し、実施形態1と同様の構成である部分については、同じ符号を付して説明する。図7は、実施形態2に係る成形治具を用いた成形方法に関する説明図である。
