Abstract :Carbon fiber reinforced composite materials (CFRP) are being widely used in aircraft parts and unmanned air vehicle (UAV) airframe production due to their high specific stiffness and strength. Besides their superior characteristics, they have a disadvantage of poor electrical conductivity when used in UAV airframes which subjected to lightning strike during their service life. In order to protect UAV airframe from lightning strike damage, adding a metal wire to CFRP composite is an alternative method. Moreover, UAV and aircraft airframe materials subjected to solid particle erosion damage during their service life also.Surface damage induced by solid particle erosion cause aerodynamic losses and result with increase in specific fuel consumption or shortening of maximum air vehicle range. Also worn body could be lost its lightning strike residence. It is evident that there is no much literature study about CFRP - metal wire hybrid reinforced composites solid particle erosion behavior. The aim of this study is to characterize the solid particle erosion behavior of CFRP - metal wire hybrid reinforced composite and analyze the post wear damage induced in the surface of the samples. Solid particle tests were performed according to ASTM G 76 standard in a specially designed test rig.Mass loss and erosion rate measurements after tests were done and damage mechanisms were discussed. Surface roughness analysis of specimens before and after solid particle erosion tests were performed by using 3D non-contact laser profilometer.
