Influence of Temperature on the Fatigue Behaviour of Glass Fibre Reinforced Polypropylene

: The behaviour of a composite with a polymeric matrix subjected to fatigue was analysed. The study was conducted at ambient temperature, as well as at 50 and 100 °C. The material was observed to behave differently at each temperature. Furthermore, a statistical analysis was performed using Castillo’s model. Although certain similarities in behaviour were observed at ambient temperature and 50 °C, the material behaved differently at 100 °C. Structural modifications were found in the thermal analysis that justify these differences.
