Abstract

This study investigates the degradation of carbon fiber-reinforced plastic composites, fabricated via non-autoclave molding, under tropical climatic conditions across three regions over three years. Forty specimens (10 control, 30 exposed) with 2x2 twill weave and 0°/90° fiber orientation were subjected to tensile and compressive testing, microscopy, and X-ray computed tomography. Control specimens established baseline properties, while exposed specimens underwent three-year weathering. Statistical and principal component analyses revealed significant mechanical degradation, with tensile strength decreasing by up to 16.1% (p
