Review on Mechanical and Thermal Properties of Pineapple Leaf Fiber (PALF) Reinforced Composite

Synthetic fiber composites are used in diversified applications because of their high strength-to-weight ratio. The energy associated with the production of synthetic fibers and their non-degradable characteristics is a major factor of concern looking from an environmental point of view. Natural fibers are derived from plants and animals, are biodegradable, and have properties similar to synthetic fibers. Pineapple leaf fibers (PALF) are obtained from pineapple leaves and can be effectively used as a reinforcement in the polymer matrix. PALF-based composite can be used in automobile, aerospace, sports, biomedical and furniture industries. Utilizing pineapple leaves for producing fibers which will be used in composites will not only reduce the associated environmental problems but also will give lucrative income opportunities to farmers and industries. This review paper deals with surface treatment methods for PALF. Mechanical and thermal properties of PALF reinforced composite are discussed in detail. The hybrid composite formed by PALF as one element is discussed. Overall, this review article highlights the previous work and identifies the gap for future research in the field of PALF reinforced composites.
