Comparative analysis of physical properties of laminated composites and 3-D woven reinforced composites under elastic impact

Glass fiber was used as warp and weft yarn of 3-D woven fabric, aramid fiber was used as Z-yarn to prepare 3-D orthogonal woven fabric, basalt fiber was used as warp and weft yarn of laminated fabric, and these two fabrics were used as reinforcing bodies, and vinyl resin was used as matrix to prepare reinforced composites. The ballistic impact tests of the two composite materials were carried out in the range of 310~790 m/s bullet initial velocity, and their anti-elastic energy was compared. The results show that the energy absorption value of the 3-D orthogonal woven composite is much larger than that of the basalt laminated composite, the residual velocity of the bullet after impacting the composite target is linear with the initial velocity.
