process of obtaining an anti-trauma layer for application in an impact attenuation and energy dispersion system

摘要

For the joining, in a single loom stage, of at least two sheets of fabric (2) and (3) through the interlacing of their faces by means of fibers concurrent to the plane of the fabrics (4), forming an anti-trauma ballistic layer (1). The spacing of the fabric sheets (2) and (3) occurs according to the length of the competing fibers (4), determining the desired thickness for the anti-trauma ballistic layer (1), according to the type of protection in which it will be applied. . At the moment of the impact by the projectile, the energy of the shock wave of the impact disperses along the length of the competing fibers (4) between the sheets of fabric (2) and (3), and by these same fibers (4) , through its compression, energy is absorbed, the expansion of the shock wave and the stretching of the tissue sheets (2) and (3). With this effect, there is less deformation of the bulletproof vest, for example, avoiding traumatic shock and maintaining control of the trauma caused by the impact and the recorded BFS deformation (BackfaceSignature).
