Pineapple leave fibre (PALF) is one of the abundantly available waste materials in India and has not been studied yet as it is required. A detailed study of chemical, physical, and mechanical properties will bring out logical and reasonable utilization of PALF for various applications. From the socio-economic prospective, PALF can be a new source of raw material to the industries and can be potential replacement of the expensive and nonrenewable synthetic fibre. However, few studies on PALF have been done describing the interfacial adhesion between fibres and reinforcement compatibility of fibre but a detailed study on PALF properties is not available. In this review, author covered the basic information chemical, physical, and mechanical properties of PALF. Furthermore, it summarizes the recent work reported on physical, mechanical, and a thermal property of PALF reinforced polymer based composites with it is various applications.
