Abstract

Nowadays,increasing in researches about renewable natural fibre had been done in order to become one of the elective arrangements in supplanting the synthetic fibre. Besides,the natural fibres have minimal effort of production yet have a good set of mechanical properties and natural well disposed.Among of the natural fibre resources is pineapple leaf fibre (PALF) that had been widely planted in Malaysia.For the current study,PALF contain high cellulose and exhibit great mechanical properties particularly from Josapine family.Therefore in this study,the PALF from Josapine was used as reinforced materials and the binder was thermoplastic corn starch (TPCS) and the effect of the PALF loading and PALF fibre length on the mechanical,physical and environmental properties of treated PALF/TPCS composites also have been analysed.Fibre loading was fixed since 20/80,30/70,40/60, 50/50 and 60/40 followed by 10 mm and 30 mm of PALF length.PALF has been undergoing alkaline treatment to increase the strength of fibre than proceed to hot press forming process.All samples have been undergoing nine different tests to determine the mechanical,physical and environmental properties of PALF composites.The test has been conducted to determine the mechanical properties including tensile test,flexural test and impact test and the physical properties are density measurement,moisture content,moisture absorption and water absorption.The test to determine environmental properties are soil burial and water solubility.On the mechanical properties of the fibre,50% of the PALF loading with 10 mm in length shows the higher values of tensile strength and flexural strength which are 15.18 MPa and 25.26 MPa.Result from 30 mm in length also shows the same pattern which 50% PALF loading is the highest value,but lower compared to 10 mm fibre length which is 13.47 MPa and 18.70 MPa.
