Abstract
A lightweight, ballistic and blast-resistant multi-phase composite armor material based on a high-toughness heterogeneous interfacial layer, including a crack-arresting layer, a bullet-breaking layer, an energy-absorbing layer, and a support layer. The crack-arresting layer, the bullet-breaking layer, the energy-absorbing layer, and the support layer are stacked in sequence from a bullet-accepting side to the inside. Adjacent two layers are bonded with an adhesive film layer. The crack-arresting layer and the support layer are both made of a carbon fiber composite. The bullet-breaking layer is made of ceramic. The energy-absorbing layer is made of an ultra-high molecular weight polyethylene fiber composite. The adhesive film layer is made of a high-toughness heterogeneous interfacial adhesive.
