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.

通过估计其断裂的类型和机制对纤维复合材料进行排名

摘要 通过声发射 (AE) 方法研究了使用反应性聚合物胶体增强纤维和聚合物基体之间的界面。利用离散小波变换（DWT）建立了复合材料拉伸加载过程中断裂机理、断裂类型和声发射信号参数之间的对应关系，以及基于声发射信号连续小波变换（CWT）的断裂类型识别能量准则。通过估计初始和最终断裂应力、AE 活动、AE 信号的能量参数以及不同断裂类型的分布，对所研究的复合材料进行排序。
