Compression and Flexural Response of Carbon/Epoxy-Nanoclay Nanocomposites Subjected to UV Radiation and Condensation (original) (raw)

Abstract

ABSTRACT Compressive and flexural properties of carbon fiber reinforced composites (CFRC) infused with montmorillonite nanoclay exposed to UV radiation and condensation was examined in this study. Nanoclay contents in samples used in this study were 0 (control), 1, 2 and 3 wt%. Samples were exposed to 15 days UV radiation and condensation using QUV/SE accelerated weathering system. Compressive properties were characterized using quasi-static and dynamic loadings before and after exposure. Flexural properties were also characterized through three point bending test according to ASTM standards. Compressive and flexural properties were monitored every 5 days of exposure in each conditioning. UV exposed samples with nanoclay showed a different trend after 5 days compared to neat samples, showing an increase in strength and modulus after 10 days of exposure. Samples exposed to condensation did not follow any specific pattern, although there was a decrease in mechanical properties in all samples.
