Abstract

In this study, C-B-A and G-B-A new hybrid composites are produced by compression molding using Carbon (C), Basalt (B), Aramid (A), and Glass (G) fibers, and the produced samples are scanned using micro-computed tomography and Micro-CT. The coefficient of thermal expansion (CTE), glass transition temperature (Tg), and dimensional changes are determined by Thermomechanical Analysis (TMA) technique and thus the limits of thermal expansion and contraction dimensions, softening, and thermomechanical properties of newly produced hybrid composites are determined. In addition, the produced composites are exposed to UV radiation in different cycles and the results are compared with UV radiation non-exposed samples.
