AbstractIn this study carbon aerogels and phenolic resin were used to prepare nano polymer resin. Poly ethylene oxide (PEO) was used as the modifying agent for phenolic resin, to improve it mechanical properties and surface conductivity. The prepared nano polymer resin and carbon cloth were fabricated by compression molding. The nano-prepreg composite material via ultrasonic impregnation was prepared by the laminate was cut into test pieces to measure its mechanical (tensile, flexural and impact) properties, and surface electrical conductivity. The effect of the temperature and humidity (85 ℃/ 168hr and 85℃/ 85%RH/ 168 hr) on the mechanical properties were investigated. Results reveal that the surface conductivity increased by 64.55%, the tensile strength measured at room temperature increased by 35.7%, the flexural strength increased by 18.4%, and the impact strength increased by 101%. In a hot environment (85℃/168hr), the tensile strength was reduced by 23.8%; the flexural strength was increased by 3.1%, and the impact strength was increased by 84.6%. In a high temperature-high humidity environment (85℃/ 85%RH/ 168hr), the tensile strength was reducted by 29.6%; the flexural strength was increased by 17%, and the impact strength was increased by 95.7%.
