The present analysis intends to look into the needlepunched nonwoven textile material reinforced polymer composites. The solid particle erosion wear behavior of needlepunched nonwoven fabric mat reinforced epoxy composites were assessed using silica sand particles with the size of 250, 350, and 450 μm. Taguchi analysis was also carried out on the basis of design of experiments (DoE) approach to establish the interdependence of operating parameters. Mechanical and physical properties of composites were also evaluated experimentally, and the storage modulus (E′), loss modulus (E″) and damping factor (tan δ) characteristics were analyzed with the help of dynamic mechanical analyzer (DMA) in the temperature range of 20–200°C. Surface morphology of the eroded surfaces of composites were also analyze by scanning electron microscopic (SEM) to discuss the feasible erosion mechanism on composite surfaces. The result reveals that fiber content and impact velocity has an invulnerable impact on the erosion rate of needlepunched nonwoven fabric mat‐epoxy composites. The mechanical and physical properties are meliorating with incorporation of fabric mat weight percentage in composites, and the measured damping factor (tan δ) peaks of T g for needlepunched nonwoven fabric mat epoxy composites ranged from 100 to 110°C.
