Mechanical Properties of Pineapple Leaf Fibre Reinforced Polypropylene Laminated Composites

Pineapple leaf fibre which is rich in cellulose,relatively inexpensive and abundantly available has the potential to be used as reinforcement in polymer composite.The present research investigates the tensile, flexural and impact behaviours of pineapple leaf fibrepolypropylene(PALF-PP) composites a...
