The Impact

Polyamic acid (PAA) containing aromatic ester was synthesized and used to modify the epoxy resin (E-51)/PAA curing system. The mechanical properties, dynamic mechanical properties, fracture surface morphology, and thermal properties of the E-51/PAA curing systems were systematically investigated. Experimental results revealed that the impact strength of the cured systems modified with PAA are 3 to 4 times higher than that of the unmodified system, and enhanced the thermal decomposition temperature by about 15°C, while the storage modulus is also higher than that of the unmodified system, and the fracture surfaces of modified systems display tough fracture feature.
