Mechanical characterization of basalt fibre reinforced composites using energy methods

Abstract

The use of basalt fibres is gaining increasing attention due to their relatively low cost, favourable mechanical properties, and reduced environmental impact. In particular, basalt fibre composites are being explored as potential substitutes for fiberglass, given the significant environmental footprint of glass fibres. However, ensuring the structural integrity and reliability of structures that incorporate basalt composites is crucial. This requires a detailed understanding of both their static and fatigue mechanical behaviour. Energy release analysis offers valuable insights into the mechanical performance of the materials. In this study, basalt-vinylester specimens were mechanically characterized using both Thermographic and Static Thermographic Methods. Results indicate that energy methods are effective for the characterization of complex materials like basalt composites, with consistent findings between the two techniques.
