Determination of static and fatigue characteristics of carbon fiber reinforced polyester composites for automobile applications

Abstract

In this research, suspension through carbon fiber reinforced polyester fiber has given importance because of its adaptability. Leaf springs were moulded the usage of 20% short carbon fiber reinforced polyester (SF), 20% length carbon fiber reinforced polyester (LF) as well as Unreinforced polyester (UP) are evaluated for the joint strength. For determining energy storage, capability and strain rate sensitiveness of moulded leaf spring static overall performance assessments had been completed. Check joints had been subjected to absolutely reversed fatigue loads, at fixed frequency fatigue; leaf spring performance changed into evaluated, with diverse loads until 2 × 107 cycles. The tensile surface failure morphology of the cracks has exhibited via the Scanning Electron Microscope (SEM). The results confirmed the suitability of carbon fiber reinforced polyester fiber for load utility over other taken into consideration materials.
