Abstract
Micron sized alumina particles (≤10 µm) are incorporated between the plies of a conventional glass fabric reinforced epoxy (GE) composite to improve the fracture toughness ( K IC ). The influence of the alumina filler content (0, 7.5, and 10 wt%) on K IC are investigated. These composites are prepared by hand layup assisted by the vacuum bagging method. The prepared composites are evaluated for K IC at room temperature, elevated temperature (100 °C) and at cryogenic temperature (−15 °C). The K IC test was conducted utilizing single notched edge bend specimen under mode I according to ASTM D5045 standard. The test results indicated that K IC of GE is improved by addition of alumina particles. Furthermore, these composites maintained higher K IC at −15 °C and decreased significantly at elevated temperature. The maximum K IC is recorded at particle loading of 10 wt% GE hybrid composite.
