Abstract
An high-velocity impact-resistant wave-transparent composite, including an upper composite layer, a lower composite layer, and a bio-inspired nacre-like toughening structure arranged therebetween. The toughening structure has a soft-hard alternating nacre-like structure, and is made from a low dielectric constant sheet material and a resin. The upper composite layer and the lower composite layer are each independently made of a fiber-reinforced resin composite, a foam material, or a honeycomb material. A preparation method of the high-velocity impact-resistant wave-transparent composite is further provided.
