Effects of ultraviolet radiation and condensation on static and dynamic compression behavior of neat and nanoclay infused epoxy/glass composites

Abstract

Effects of ultraviolet radiation and condensation on the static and dynamic compressive properties of composites with and without nanoclay were investigated. Specimens were exposed to ultraviolet radiation (UV), and alternate ultraviolet radiation and condensation (UC) conditions for 5, 10, and 15 days, respectively. Compression test results showed an increase in strength and modulus with increase in strain rate and nanoclay weight percent loading. However, properties degraded upon conditioning with nanoclay infused systems showing less degradation. Scanning electron micrographs of fractured samples show better interfacial bonding in nanoclay infused composites in 2 wt. % system showing best properties.
