Abstract
Abstract: For many applications, such as vests or parts of vests, the fibers are used in fabric, mat, or mesh. Ballistic resistance properties are also improved by the development of special fabrics architectures. It is known that heat and oxygen are the main factors in the aging process of polymers. The mechanisms of aging by oxidation can be investigated by monitoring the mechanical properties of a material exposed to prolonged aging in an oven, which is called the accelerated aging process by thermal oxidation. In previous studies, the epoxy matrix composite reinforced with 40% by volume of fique fabric, already tested and with good ballistic performance, was developed and proposed for individual ballistic protection applications. However, the impact of different environmental conditions on the dynamic properties of the composite has not been studied. Therefore, the present study, for the first time, aimed to apply accelerated weathering through high temperature to the composite, as well as to the epoxy matrix, aiming to evaluate the influence of aging.
