▎ 摘　　要

NOVELTY - Metal composite material of biomimetic double penetration structure comprises integrally formed dense titanium, porous titanium, and integrally formed dense aluminum alloy and porous aluminum alloy. The metal intermediate layer of the bionic double penetration structure of composite material is a titanium/aluminum metal intermediate layer, which is composed of a titanium alloy porous lattice and an aluminum alloy porous lattice, and the titanium alloy porous lattice and the aluminum alloy porous lattice. The aluminum alloy is 2 series-7 series grades, the ceramic particles are aluminum oxide, boron carbide, silicon carbide, titanium diboride , aluminum nitride, silicon nitride or salon ceramic particles or carbon nanotubes or graphene. USE - The composite material is useful in aerospace, military equipment and ocean engineering.e used in anti-armour weapons, such as helicopters, armored vehicles and other vehicles. ADVANTAGE - The bionic double-penetration structure of metal composite material anti-multi-bomb striking ability is effectively improved. The method is simple and easy, the process is easy to control the short production period, it can realize mass production, and the whole performance of the material and the service behavior is optimized and improved. It solves the problem that the existing composite armor material is invalid due to adhesive layer, ceramic crushing and splashing, panel/back plate separation and structural integrity is bad. The titanium alloy porous lattice structure is complementary with the aluminum alloy, using titanium alloy porosity lattice to form strong constraint to the aluminum alloy structure. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of metal composite material with biomimetic double-penetration structure.
