Effect of moisture absorption on the thermo-mechanical properties of carbon/epoxy composites with SiC reinforcement

Popis výsledku v původním jazyce

Carbon fiber reinforced polymer (CFRP) composites have many applications in civil engineering, aircraft industry and in many other areas. They are lightweight composite materials with outstanding mechanical properties. In this study, the testing specimens were made from the carbon fabrics impregnated with epoxy resin which had been reinforced with the silicon carbide (SiC) microparticles or SiC microfibers. The four-layered composite samples were fabricated by means of hot compression and curing of epoxy resin. The thermal, tensile and impact properties of the untreated specimens were compared with the ones that underwent the water absorption in duration of 72 hours, followed by desorption. The treated specimens containing the SiC particles and SiC microfibers demonstrated 3.4% and 8.8% of the reduction in the tensile energy absorption, correspondingly, compared to their untreated counterparts. Opposed to this trend of results, the tensile energy absorption value of the treated carbon/epoxy specimens, experienced an increase of 84.4% compared to the dry carbon/epoxy specimens. The additional test results showed that the water treated carbon/epoxy composites went into a certain decline in their thermal, tensile and impact properties. The obtained results provide some significant pieces of information for the future practical use of the presented composites.
