8/16/2023 0 Comments Carbon fiber suit of armor![]() ![]() Carbon-fiber/epoxy, one of the best structural materials available due to carbon’s stiffness, high tensile strength and extremely low elongation, is therefore a poor performer from a ballistics standpoint. Unfortunately, each is a failure mechanism that all good structural materials are supposed to avoid. These include spall formation, tensile fiber failure of primary yarns, fiber debonding, fiber pullout and interlayer delamination. Antiballistic materials, reinforced with aramid or various types of polyolefin fibers with superior elongation-to-break characteristics, absorb and dissipate the energy of a high-velocity impact through a number of energy-absorbing mechanisms. For example, a fiber reinforcement and matrix must, by design, capture and stop projectiles. Until recently, there were good antiballistic materials and good structural materials, and - materials engineers and end-users have usually assumed - never the twain shall meet.
