ABSTRACT
A uni-direction (UD) laminate and three-dimensional (3D) orthogonal woven fabric made
of ultra high molecular weight polyethylene (UHMWPE) are used as main reinforced units
combined with aluminum alloy plates to form a reinforced sandwich structure. Penetration
tests are carried out on four composite reinforced structures with different structure forms by
a 7.62mm steel core projectile. The target plate size is 150mm×150mm. Besides, Ansys/LS-
Dyna software is applied to simulate the penetration process, and the simulation results are
in good agreement with the test results. All the results demonstrate that with the same total
thickness of UD laminates, 20mm UD laminates have better penetration resistance than
four 5mm UD laminates. The less the number of UD laminates, the better anti-penetration
performance of the overall structure. The 3D orthogonal woven fabric has the advantage of
spatial integrity, which can effectively restrain deformation of laminates and absorb energy
behind UD laminates, so as to obtain better anti-penetration performance. In the core
structure with a total thickness of 28mm, when the thickness ratio of 3D orthogonal woven
fabric is between 30% and 35%, the protection ability and lightweight requirements of the
sandwich structure can be better considered.
