Abstract

AbstractFiber reinforced polymer composites (FRPC) offer advantages including lightweight, flexibility of design, ease of fabrication, long service life, superior mechanical performance, etc., over conventional materials such as steel, aluminum, wood, etc. Their market has grown significantly ($101.6 billion by 2026) in automotive, aerospace, sports, and construction in the last decade. In spite of numerous benefits, these materials are complex and heterogenous in nature and have certain issues as well. Residual stress is one of these problems because two or more heterogeneous materials are present in a composite. This stress leads to deformation, fracture of the matrix, delamination, reduced strength, buckling of the fibers, etc. in a composite part. In this chapter, we discussed the factors that induce residual stress in composite material parts and its related issues. Methods for evaluation and simulation of residual stress in such materials are also discussed briefly.KeywordsFiber reinforced compositesResidual stressShape distortionSpring-inWarpage
