Examination of Mechanical Tests of CFRP Composite Material with Different Orientation Angles Used in the Automotive Industry

Abstract

Carbon fiber reinforced polymer (CFRP) composites, which have good mechanical properties, are widely used in many sectors today. Carbon fabrics/epoxy composites are materials used in the production of various components in many professional in-dustries such as aerospace, construction, textile and automotive. The use of CFRP composite lightweight materials has begun to increase in the automotive industry to reduce emissions, increase crash resistance and save fuel. In order to evaluate mate-rials in these industrial areas, it becomes important to know their mechanical proper-ties such as tensile strength and three-point bending. In this study, carbon fiber rein-forced polymer (CFRP) [0°/0°], [0°/90°], [±45°] and [0°/90°/+45°/-45°/-45°/+45°/90°/0°] four different types of orientation CFR materials were used.Tensile and three-point bending tests were performed on the samples produced with 4 differ-ent orientation angles. Three-point bending tests were carried out in accordance with ASTM D7264 standards and tensile tests were carried out in accordance with ASTM D 3039 standards. Stress-strain and force-strain curves were drawn. It has been ob-served that the material type that withstands the maximum force the most is the C48 structured CFRP material with an 8-layer [0°/90°/+45°/-45°]s arrangement. However, it was concluded that the carrying capacity of the C48 sample was higher than the samples with different fabric orientation.
