Abstract
A composite product substantially reduced the impact force imposed by hard impactor which travelled at the speed in the range of 400 m/s to 1400 m/s simultaneously damping the vibrations and shocks appeared therein is disclosed. At the same time it is light weight with the weight lower than that of 22 to 38 kg/m2and is flexible to adopt the shape suitable for the end applications. A method of manufacturing the composite product of the invention is also disclosed.
Claims13
A composite product comprising:
- at least three layers selected from a thermoset layer, a glass layer, a composite layer, and a planar layer, wherein,
- the thermoset layer is made of a powder of waste hybrid composites or waste ceramic, wherein the thermoset layer is planar and made up of interlocked, shaped blocks,
- the glass layer includes,
- at least one glass sublayer having a plurality of hexagonal units of glass fabric impregnated with an epoxy resin system, wherein the hexagonal units are surface treated with a bonding agent, arranged in an X-Y plane, and fused with a layer of compounded rubber, or
- at least two of the glass sublayers including the plurality of hexagonal units fused with a middle layer of the compounded rubber,
- the composite layer includes,
- a first composite sublayer having, multiple fused layers of HDPE with a solvent-based elastomeric adhesive layer, or multiple stitched layers of HDPE, and
- a second composite sublayer of the composite layer having multiple stitched layers of PET, and
- the planar layer is made of a composite core of synthetic polyester felt impregnated with a first resin system, wherein the core is encapsulated between bi-directionally and/or uni-directionally-oriented synthetic fabric selected from at least one of, polyester, carbon, aramid, glass, and basalt, and impregnated with a second resin system;
- and
- an upper superior layer of a fabric encapsulating the at least three of the thermoset layer, the glass layer, the composite layer, and the planar layer, wherein the composite product is configured to reduce impact force of high-speed projectiles and damp vibrations and shock from impact of the high-speed projectiles.
