Polyolefin fiber, polyolefin fiber reinforced composites and their applications: a review

Fiber reinforced polymer composites (FRPC) are widely used in current developing world due to their huge advantages of high specific strength, durability, low cost and weight reduction. But, major issue with this composite is their recyclability. To overcome this, researchers are considering polyolefin fiber for reinforcement purpose which can be reused and recycled and can be used as a reinforcement for concrete for industrial pavement to improve their tenacity. Polyolefin fibers also offer exterior impact strength to the composite because of their ductile nature. Due to their excellent impact property, they are used in high ballistic armor. This review paper contains the details about the FRPC, their processing technique, recent advancement in the processing technique VARIM, polyolefin fiber, properties of polyolefin fibers like polyethylene fiber and polypropylene fiber, polyolefin reinforced polymer composite, hybrid composite and their applications.
