Engineered short-cut fibers are utilized as reinforcement in a variety of matrix composites, metal matrix composites to deliver tensile and flexural strength, improve modulus of rupture, cold crush strength, good wear resistance, surface porosity, and promote specialty properties such as making composites radiopaque. Engineered short-cut fibers are essential for the functioning of composites at harsh conditions, such as high temperatures, ultra-high vacuum, and aggressive chemical media.
