Resumen:
In order to understand material’s behavior structural observations must be correlated with material’s properties. In this work a combination of microscopy techniques – transmition optical microscopy (TOM), scanning electron microscopy (SEM) complemented with backscatterd electron images (BEI) and electron probe microanalyses (EPMA) – was used to elucidate wear and fracture failure mechanisms of thermoplastic composites. High density polyethylene/molybdenum disulphide composites were investigated. Different features were elucidated: composites morphology, relationship between MoS2 content and microstructure, and the correlation structure/damage mechanism/property. Results demonstrate that wear and fracture failure mechanisms strongly depends on composites’ microstructure and morphology.
