Influence of composite material components on laser irradiation effects of resin-based composites

Background: Resin-based composites with excellent properties are increasingly being utilized in laser environments, where the components of composites significantly influence the laser irradiation effects. Methods: This study investigates the influence of resin thermal stability and fiber type on the laser irradiation effects of resin-based composites under consistent laser parameters. The research results show the polyurethane-based composites, with the lowest thermal stability, exhibit the lowest back surface temperature under laser irradiation. In contrast, the boron phenolic-based composites, with the highest thermal stability, show the highest front and back surface temperatures. Moreover, quartz fiber-reinforced composites, with lower thermal conductivity, are more susceptible to penetration under laser irradiation compared to carbon fiber-reinforced composites with higher thermal conductivity. Significant findings: Therefore, the impact of different components on the laser irradiation performance of resin-based composites does not follow a single pattern. And the selection of appropriate material components should be based on specific requirements in practical applications. These studies bridge the knowledge gap on ablation mechanisms of diverse-structured composites under high-energy laser irradiation, offering crucial insights and theoretical backing to bolster the safety of resin-based composites in laser-heavy settings.
