In recent years, the use of natural fiber-reinforced composites in more advanced applications has grown substantially. Applications of high strength require high mechanical properties. An effective method for increasing the field of application and mechanical properties is the hybridization of natural fibers with synthetic fibers. In this research, the effects of recycled carbon fiber hybridizing flax (Linum ussitatissimum L.) and hemp (Cannabis sativa L.) fibers were investigated to identify trends in mechanical properties resulting from varied weight fractions. A new high-performance composite was demonstrated for injection molding applications by hybridizing bast natural fibers and recycled carbon fibers in a polyolefin thermoplastic. After reinforcing recycled carbon fiber with flax and hemp fibers, this study showed a 10-15% increase in tensile strength. After reinforcing recycled carbon fiber with hemp fiber, a 30-35% increase in flexure strength was observed. Impact strength for hemp fiber also increased by 60% compared to recycled carbon fiber.
