Abstract

A reinforcement of the interface between the fiber and polymer matrix using reactive polymer colloids were investigated by the acoustic emission (AE) method. The correspondence between the fracture mechanisms, fracture types and AE signals parameters during tensile loading of composites using the discrete wavelet transform (DWT) and the energy criterion for identification of fracture type based on the continuous wavelet transform (CWT) of AE signals were established. The investigated composites were ranked by the estimation of the initial and final fracture stress, AE activity, energy parameter of AE signals, and distribution of the different fracture types.
