Interface Strength of Overmolded Thermoplastic Composites
Overmolding of thermoplastic composites is a technology in which a fiber reinforced thermoplastic blank is thermoformed and subsequently injection overmolded. Although the feasibility of the process has been demonstrated, it is acknowledged that there is a lack of proper design tools that can be used for a right-the-first-time design strategy. A model is proposed for the prediction of the bond strength between a polymer or composite insert and an injected polymer. A test method has been developed to validate this bond strength under tensile and shear loading conditions.
