The effect of fabric weaves on the damping characteristics of woven fabric composites
Fibers Reinforced Polymers (FRPs) have gained an escalating technological importance because of their excellent strength to weight ratio, ease of fabrication, and better impact resistance. Deep knowledge of their dynamic parameters (natural frequency, mode shapes and natural frequency) is essential for their appropriate use in structural applications. In this research work, damping of woven fabric composites (WFCs), a separate type of fiber reinforced polymers (FRPs), is characterized based on three different 2D fabric weaves. WFC samples were fabricated by using vacuum assisted resin transfer molding (VARTM). These samples were tested by experimental modal (EMA) analysis and dynamic mechanical analysis (DMA). Based on the experimental results, it was revealed that plain weave composites possess higher damping properties than the satin weave composites. This research also investigated the effect of fabric weaves on the natural frequencies of the woven fabric composites through numerical and experimental testing.
