  Abstract

  This research addresses the challenge of the extended duration and high number of tests required to predict the fatigue life stress of materials. To tackle this issue, a methodology is proposed based on the intrinsic viscoelastic effects of thermoplastic and thermoset-based materials and composites. The approach utilizes thermographic techniques to monitor the temperature generated during the application of a test protocol aimed at reducing the time required to predict material fatigue life. This has key applications in sectors such as automotive, aerospace, and wind energy, enhancing both testing efficiency and quality control. Furthermore, it aligns with sustainability and circular economy strategies, contributing to advances in innovative materials and industrial processes.

  Abstract

  This study analyzes the influence of accelerated aging on the fatigue properties of high-performance thermoplastic matrix composites, specifically carbon fiber-reinforced PEEK. Unidirectional and bidirectional laminates were manufactured from commercial tapes and subjected to xenon arc exposure following Cycle 1 of Method A in the UNE-EN ISO 4892-2 standard. The work combines thermal and mechanical testing to assess polymer matrix degradation and its effect on fatigue behavior. A self-heating approach is also applied as an accelerated method for estimating fatigue performance. The findings aim to enhance the understanding of the durability of these materials under service-representative conditions, with applications in aerospace, automotive, and renewable energy sectors.
