Description
以下、本開示の第1実施形態に係る複合材成形方法について、図面を参照して説明する。図1は、本実施形態に係る複合材成形方法により成形される複合材300を示す斜視図である。図2は、本実施形態に係る複合材成形方法で用いる成形型10を示す斜視図である。図3は、図2に示す成形型10のA-A矢視断面図である。
本実施形態の複合材成形方法によれば、成形型10の第1成形面11に形成される凹所12に第2繊維基材FB2が設置され、第2繊維基材FB2が設置された凹所12を覆うように、第1繊維強化部FB11が第1成形面11に固定される。第1繊維強化部FB11は、第1繊維基材FB1に含まれる複数の繊維強化シートの一部であるため、第1繊維基材FB1よりも柔軟性が高く軽量である。そのため、第2繊維基材FB2に位置ずれや皺の発生を生じさせることなく、第1繊維強化部FB11を第1成形面11に固定することができる。
次に、本開示の第2実施形態に係る複合材成形方法について図面を参照して説明する。本実施形態は、第1実施形態の変形例であり、以下で特に説明する場合を除き、第1実施形態と同様であるものとし、以下での説明を省略する。
次に、本開示の第3実施形態に係る複合材成形方法について図面を参照して説明する。本実施形態は、第1実施形態の変形例であり、以下で特に説明する場合を除き、第1実施形態と同様であるものとし、以下での説明を省略する。
本開示に係る複合材成形方法は、板状に形成される第1繊維基材(FB1)と第2繊維基材(FB2)とを一体化して複合材(300)を成形する複合材成形方法であって、第1方向(LD)に沿って延びる第1成形面(11)を有する成形型(10)の前記第1成形面に形成される凹所(12)に、前記凹所に対応する形状に形成された前記第2繊維基材を設置する設置工程(S102)と、前記設置工程により前記第2繊維基材が設置された前記凹所を覆うように、前記第1繊維基材に含まれる複数の繊維強化シートの一部である第1繊維強化部(FB11)を前記第1成形面に固定する固定工程(S103)と、前記固定工程により固定された前記第1繊維強化部に、前記第1繊維基材に含まれる複数の前記繊維強化シートの他の一部である第2繊維強化部(FB12)を積層する積層工程(S104)と、前記第1繊維基材と前記凹所に設置された前記第2繊維基材とを樹脂材料により一体化して硬化させて前記複合材を成形する成形工程(S106,S107)と、を備える。
本構成の複合材成形方法によれば、例えば、離型フィルム等のシート材を第1成形面と第1繊維強化部との間に挟んだとしても、第1繊維強化部を第1成形面に固定した後は、シート材が他の部材と接触することがない。そのため、積層工程において、第1繊維強化部に第2繊維強化部を積層する際に、シート材が移動して第1繊維基材と第2繊維基材との間に挟まれることが防止される。
