PROCESS FOR OBTAINING ANTI-TRAUMA LAYER TO BE APPLIED IN IMPACT ATTENUATION AND ENERGY DISPERSION SYSTEM

摘要

For joining, in a single loom stage, at least two fabric sheets (2) and (3) by interweaving their faces by fibers concurrent to the fabrics plane (4), forming anti-trauma ballistic layer (1). The separation between the fabric sheets (2) and (3) occurs according to the length of concurrent fibers (4), determining the thickness desired for the anti-trauma ballistic layer (1), in accordance with the type of protection in which it will be applied. Upon the impact of the projectile, the impact shock wave energy is dispersed along the length of concurrent fibers (4) between fabric sheets (2) and (3), and these same fibers (4), by their compression, absorb the energy, shock wave expansion and the elongation of the fabric sheets (2) and (3). Due to that effect, there is lower deformation of the bullet-proof vest, for example, preventing the traumatic shock and controlling the trauma caused by the impact and registered by the BFS deformation (BackfaceSignature).
