This research investigated experimentally the effect of useing of 3D fiberglass fabric in the energy absorption in glass fiber metal laminate composite made by vacuum assisted resin transfer molding (VARTM) method. The prepared GLARE is made of two or three Aluminum 2024 facing sheets and E glass/epoxy as nano composite core. Composite core section for samples of glass fiber plain weave has been composed of plain weave glass fiber 200 g⁄m^2 , 3D fiberglass fabric samples consists of 3D fiberglass fabric to thickness of 5 mm, resin R510 and hardner H515. All panels fabricated using VARTM method in section glass fiber plain weave in fiber volume fraction of 71%. Low velocity impact tests were conducted using by drop weight device at the impact energy of 50 and 80 j. The results of the low velocity impact experiments show that the amount of resistance of impact plain weave samples in comparison to the 3D fabric in various energy levels is more and better. In applications where weight is an effective agent component, the weight of glass fiber plain weave base samples is less than 3D fiberglass fabric samples.
