Temperature Effect on Fatigue Performance of Thermoset and Thermoplastic Composites

The growing demand for lightweight, durable, and high-performance materials in industries such as aerospace, automotive, and energy has driven the development and evaluation of thermoset and thermoplastic composites. Within this framework the static and fatigue mechanical behavior of one thermoset material and two thermoplastic composites are investigated in the (-30° +120°C) temperature range, to simulate extreme environmental conditions. The results from the tensile tests show the different mechanical behavior of the investigated materials, while the cyclic test results highlight the significant impact of temperature on structural properties, offering useful insights for their application in temperature-sensitive environments. This research is partially funded by the Italian Ministry of Enterprises and Made in Italy (MIMIT) within the project ”New Generation of Modular Intelligent Oleo-dynamic Pumps with Axial Flux Electric Motors,” submitted under the ”Accordi per l’Innovazione” call (DM 31/12/2021, DD 10/10/2022, automotive sector).
