Thermal Analysis of a Uniaxial Carbon Fabric Reinforced Silicone Resin

Abstract

This study, which focuses on carbon fibre (CF) reinforced silicone matrix composites (CFRS-C), an alternative to conventional polymer matrix composites, aims to understand their thermal properties better. Silicone elastomer’s high elastic deformation capability is the primary factor in the choice of silicone matrix. The aforementioned materials are particularly appealing in the design of deployable systems used in the aircraft sector due to their folding capability. Better adhesion of silicone elastomer and plain weave carbon fibre fabric was succeeded by modifying the surface of the fabrics inside 20 wt.% nitric acid solution. Thermal Gravimetry (TG) and Differential Scanning Calorimetry (DSC) were used to examine the materials’ thermal properties in this study’s scope. Thermal tests showed that composite materials exhibited thermal resistance up to 368◦C. The silicone components utilized in the study can form carbon fibre-reinforced composites that exhibit thermal stability up to the specified temperature. The use of carbon fibre enhanced the thermal stability of silicone elastomers. Additionally, a change in the number of layers impacts the composite’s thermal stability.
