(2)実施形態では、移送装置が押圧装置を介してプリプレグを移送する。また、押圧装置は、移送されるプリプレグを順次熱成形する。このため、プリプレグのサイズに合わせて、製造設備を大型化する必要がない。換言すれば、実施形態では、巨大な設備がなくても、長尺の複合材部品を製造することが可能である。
(3)いくつかの実施形態では、プリプレグの積層体を形成する前に、各プリプレグが三次元形状に加工される。そして、三次元形状に加工されたプリプレグが他のプリプレグと積層される。このため、積層体を三次元形状に加工する場合と比較して、皺が発生しにくい。また、熱可塑性樹脂を含むプリプレグのように硬いプリプレグを使用する場合には、積層体をローラなどで予成形(プリフォーム)すると、ローラに大きな負荷がかかり、また、プリプレグが蛇行し易い。これに対し、プリプレグの積層体を形成する前に、各プリプレグが三次元形状に加工される場合には、ローラによる予成形を省略(または、一部省略)でき、かつ、プリプレグの蛇行も生じにくい。さらに、従来の引っ張り方式の成形法では、プリプレグの表面に離型フィルムを配置する場合に、予成形ローラと離型フィルムとの間の大きな摩擦力に起因して、離型フィルムの皺の発生および破損が発生しやすい。これに対し、実施形態では、プリプレグの積層体を予成形する必要がないため、予成形ローラと離型フィルムとの間の摩擦力を低減できる。その結果、離型フィルムの皺の発生および破損が発生しにくい。
(4)いくつかの実施形態では、押圧装置は、曲線軌道に沿って移動する。このため、曲率を有する複合材部品の連続成形が可能である。
