Time Dependent Behaviour of PMMA-Toughened Siliconized SiC Strengthened Glass-Epoxy Composite

The objective of this study was to look at the time-dependent behaviours of a PMMA toughened SiC particle added glass-epoxy composite. The primary goal of this study was to look at time-dependent behaviours including fatigue, fracture toughness, and viscoelasticity following toughening using PMMA and SiC fine fillers. The SiC particles used as a strength compensator were siliconized in an aqueous solution using 3-Aminopropyltriethoxysilane. All of the composites were made by hand layup process and characterised according to ASTM standards. The addition of PMMA to the epoxy resin increased energy absorption and release, according to the findings. Similarly, the SiC particle enhanced the composite’s total energy storage. The scanning electron microscope images demonstrated that the SiC particles were uniformly dispersed and adhered to the matrix. These high toughness glass-epoxy composites might be employed in high-damping-load applications, such as structural component fabrication, and vehicle body assembly.
