In, this research, the effects of adding silica and multiwall carbon nanotubes (MWCNT) nano particles on the low velocity impact response are experimentally studied. Vacuum assisted resin transfer molding (VARTM) method has been used to manufacture nano composite with 11 layers of plain weave carbon fibers 200 g⁄m^2 , resin R510 and hardener H515 with 66% fiber volume fraction. Samples made of nano silica and MWCNT particles have been dispersed with 1 wt. %. The prepared CARALL is made of two Aluminum 2024 facing sheets. Low velocity impact tests have been conducted using by drop weight device at the impact energy of 20, 40 and 60 j with velocity of 2.6, 3.68 and 4.5 m⁄s . The results of the low velocity impact experiments indicates that the MWCNT improves performance of fiber metal composite material and the effects of MWCNT in improving the impact properties of fiber metal laminate composite is better than of nano silica. Better adhering and dispersion of MWCNT and strong interfacial creation are some other effect factors of impact response sample reinforced with multiwall carbon nanotubes in comparison to nano silica.
