Resumen:
In order to understand materials behavior structural observations must be correlated with materials 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.
