Abstract

Pineapple leaf fibre (PALF) is rich in cellulose,relative inexpensive and abundantly available.In this project, tensile strength and modulus of PALF reinforced polylatic acid (PLA) is investigated.PALF surface modified is using alkaline treatment order to improve the wettability between matrix.Fourier transform infrared spectroscopy are confirm the present of sodium hydroxide and removal of pectin from the surface of the fibre.PALF/PLA composites is produced various fibre content (40 wt. %, 50wt%,60 wt. % and 70 wt. %) using pre-pregging technique and compression moulding.In addition,1 wt. % of CNT is added to 70 wt. % of PALF/PLA composites to compare the influence of nanofiller to the composites system. Mechanical testing shows the maximum tensile strength and modulus is 232.264 MPa and 27.015 GPa is given by 70 wt. % PALF/PLA composite.Addition of 1 wt. % of CNT,further increased their properties to 243.092 MPa and 30.08 GPa for tensile strength and modulus respectively.The fracture behaviour of the composites is investigated by using Scanning Electron Microscopy (SEM),shown the composites have good bonding between matrix and fibres even at high fibre loading due to the effective of pre-pregging approach.
