Abstract
The effects of integrating micro-Al2O3 onto carbon fiber surface and its contents on mechanical properties of carbon fiber reinforced polymer composites were investigated. Mode II interlaminar fracture toughness, impact strength, flexural properties and initial modulus were determined by mechanical test machines and dynamic mechanical analyzer. The reason for performance improvement was discussed based on scanning electron microscopy. The mode II interlaminar fracture toughness, impact strength, and flexural strength of composites without addition of micro-Al2O3 were 348Â J/m2, 118Â kJ/m2 and 682Â MPa, respectively. However, the mechanical properties of modified composites were improved significantly. The mechanical properties were optimum when the areal density of micro-Al2O3 particles reached 15Â g/m2 at which the mode II interlaminar fracture toughness, impact strength, and flexural strength reached 522Â J/m2, 161.7Â kJ/m2 and 759Â MPa, respectively. Furthermore, these composites with addition micro- Al2O3 in the layers showed an improvement in thermal property.
