Effect of Laminates Orientation on Impact Properties of Fiberglass and Kevlar Composite Panels

This paper presents the study of the effect of laminates angle on impact properties of a composite panel made of glass and Kevlar fibers using finite element modelling. In this research, the composite panel consists of a skin panel, specifically the front left wing, from an automotive vehicle having multiple configurations. A distributed pressure on the composite package represents the loading on the selected panel modelled as one uniform distributed abuse loading case and the stress variation within the composite panel for each configuration is determined. The results of these analyses are used for the determination of mathematical models for tensions, longitudinal and shear tensions, as functions of laminate angle for each configuration.
