Abstract

The effect of interlayer materials on the damage of ceramics in the SiC/Al compositestructure was analyzed through experiments and simulation. Using 0.25 mm thermoplasticpolyurethane (TPU) as a reference, a 0.5 mm aramid fabric (AFRP) or a 0.5 mm carbon fiberreinforced epoxy matrix composite (CFRP) was added to the interlayer, respectively. Through theimpact tests, it was discovered that the ceramic damaged area in the TPU composite structure wassevere. With the addition of AFRP, the damaged area of the ceramic layer was reduced by 73%under the same impact conditions. The addition of CFRP also reduced the damage of ceramics. Theevolution process of the tensile stress on the ceramic rear surface was presented by simulation. Thetensile evolution process analysis can explain the experimental phenomenon well and can be usedto predict the damage of the ceramics.
