The interfacial reinforcement between polypropylene (PP) and a polyamide (nylon 6, Ny6) has been investigated by in-situ reactive compatibilization. The effects of bonding time, and temperature on the interfacial fracture toughness of the adhesive joint were studied. The fracture toughness increased after some induction time; then, it reached a plateau value. The fracture toughness increased with the bonding temperature, showed a maximum and then decreased at a higher temperature. The dependence of the fracture toughness on the bonding time is plausibly explained in terms of this fracture mechanism. The fracture mechanism change was checked using the adhesion system between a flexible folded chain polymer (functionalized polypropylene - maleic anhydride grafted polypropylene, MAPP) and a rodlike polymer (a themotropic liquid crystalline polymer, TCLP - poly(ester amide)). |
