In recent years, the interest in recycled and sustainable materials in engineering applications has grown due to the need to reduce environmental impact and industrial scrap wastes, especially in composite material applications. Among the reinforcements that can be used in composite production, non-woven random mat carbon fibers are one of the most interesting solutions, since they allow the use of the scraps coming from the production of carbon fibers using a very easy and low energy consuming method. In this study, the mechanical properties of non-woven carbon fiber/epoxy matrix composites have been investigated by means bending, compression, tensile, and shear tests.
