下記、試験装置、試験片、試験条件で試験を行った。
・試験装置名:精密万能試験機 (島津製作所製:オートグラフ)
・試験片:板状部材11と樹脂部材12の接合部から幅40mm×長さ50mmの試験片を切り出した。
・チャック間距離:30mm
・クロスヘッドスピード:1.6mm/min。
樹脂部材12における立ち壁19(図1参照)から板状部材11との接合部に対して、直角にL型のステンレス製の定規を立てて当て、該ステンレス製定規と接合部の表面との間に隙間ゲージを挿入して、間隙の有無およびその大きさ、すなわち、接合部の反りを測定し、各サンプルの最も反りの大きい箇所の数値を、接合部反りとした。
射出成形により成形された複合成形品10の凹凸形状接合面における凹凸の繰り返し単位の長さを、定規による測定および計算によって求めた。凹凸形状の輪郭線の一部に丸みを有する線分が存在する場合は、その丸みの半径または直径を測定し、その値から円周を求める公式により、実際の接合線の長さを計算した。各凹凸の繰り返し単位における接合線の長さの合計を、直線からなる凸部通過線の長さ、すなわち、平行方向長さで割って、凸部通過線の長さ、すなわち、平行方向長さ1mm当たりの実際の接合線の長さとした。
射出成形により成形された複合成形品10の凹凸形状接合面における凹凸の繰り返し単位の長さを、定規による測定および計算によって求めた。凹凸形状の輪郭線の一部に丸みを有する線分が存在する場合は、その丸みの半径または直径を測定し、その値から円周を求める公式により、実際の接合線の長さを計算した。凹凸の繰り返し単位毎に、凸部が1個存在するため、その繰り返し単位当たりの凸部通過線の長さを定規で測定し、100mmを、繰り返し単位当たりの凸部通過線の長さで割って、凸部通過線の長さ100mm当たりの凸部の数とした。
射出成形により成形された複合成形品10の凹部の深さを定規で測定した。
