Hybrid composite structures for ballistic protection

a composite structure and ballistic protection technology, applied in the direction of protective equipment, weapons, armour, etc., can solve the problems of reducing the mobility and speed of the vehicle, reducing the stiffness of the resulting structure, and the existing type of two-layer composite armor has poor structure integrity and less multi-hit resistance, so as to improve the ability to withstand multiple impacts/hits, improve the structural integrity, and absorb high-impact energy.

Benefits of technology

[0008] In still another embodiment, the hybrid composite armor of the present invention comprises at least one hard ceramic face/layer to blunt a projectile, at least one backing layer, and at least one intermediate layer positioned between the one or more face layers and the one or more backing layers. Either the one or more intermediate layers or the one or more backing layers is/are designed to primarily provide structure integrity and to impart multi-hit capacity to the armor of the present inven

Problems solved by technology

Traditional armor vehicle is protected by heavy metal armor which not only produces fuel energy and transportation problems, but also reduces the mobility and speed of the vehicle significantly.
Due to intensive fracture and delamination in composite backing plate after

Description

FIELD OF THE INVENTION [0001] The present invention relates to hybrid composite structures with improved ballistic protection properties. More specifically, the present invention relates to hybrid composite structures with improved ballistic protection properties that comprise at least three sub-layers. BACKGROUND OF THE INVENTION [0002] The recent anti-terrorism war in Iraq and other US military missions have demonstrated the advantages of well-prepared, small, mobile and lethal combat forces that can rapidly respond to a broad range of tasks in limited regional conflicts. The new strategy of US military forces presents an urgent need for “leap frogging” technologies. Weight reduction for present and future army combat systems is critical to the rapid deployment of military contingencies under the requirement of this new strategy. Traditional armor vehicle is protected by heavy metal armor which not only produces fuel energy and transportation problems, but also reduces the mobilit...
