In order to study the influence of fiber hybridization on the low-velocity impact performance of 3D woven composites,two kinds of composites of T700 carbon fiber reinforced and E-glass/T700 fiber hybrid were fabricated based on the same interlock 3D woven structure.Low-velocity impact experiments were carried out, and the impact energies were set as 10 J,23 J and 40 J,respectively.The results show that under the impact energy of no more than 40 J,the two composites are not broken.Under the three kinds of impact energies, the peak forces of hybrid materials are smaller than that of all-carbon materials,but hybrid materials have better impact energy absorption capability and larger maximum displacement.Under the impact energy of 10 J and 23 J,the damage degree of hybrid materials is smaller than that of all-carbon materials. However,when the impact energy reaches 40 J,the damage degree of hybrid materials is greater than that of all-carbon materials.
