補強材料は、予熱された(150℃)型に入れられ、次いで、型は、部分的に閉鎖され、数分で約350℃の温度に加熱される(工程(c))。型のキャビティの温度は、325℃で1.5分間維持される(工程(d))。ポリマー組成物は、335℃(工程(e))及び0.1MPa未満の圧力において、2〜10cm3/秒の速度で注入されて、空いているキャビティを満たす。注入を停止し、所望の最終部品の厚さに達するまで、0.003〜0.05MPa・s−1の圧力速度を使用して型を徐々に閉鎖する(工程(f))。冷却を開始する。型の温度は、約150℃に下げることができる。型が開放され、複合物品が取り出される。
手順Aの手順を、型の温度が200℃に設定されたことを除いて使用した(即ち米国特許出願公開第2013/0001817A1号明細書に開示されているように、成形組成物の溶融温度より低い)。

手順A〜Dのいずれかで作製された複合物品は、オーバーモールドにそのまま使用されるか、又はこの手順Fに従い、事前に0.2〜2.5ミリメートルの厚さのポリマー被覆でオーバーモールドされた物品として使用される。本発明によるオーバーモールドされた複合物品は、以下に記載される手順により、複合物品(厚さ1.75mm:4つのプライ)に対して約1〜1.5mmの厚さのオーバーモールド樹脂組成物(ポリマーA−7)を射出成形することによって作製された。
手順Fで作製したオーバーモールドされた複合物品を、ダイヤモンドブレード及び水冷を使用して、幅1.25cm、長さ6.5cmの試験片に切断した。試験片の引張り側(外側のスパン)でビームを支持することによる4点法を使用して、複合構造へのオーバーモールドされた樹脂組成物の接着/結合強度を特性評価した。
