Abstract

This research is focused on investigating the effect of fibre loading of PALF reinforced cornstarch biodegradable plastic composite to the physical and mechanical properties. Recently, a lot of research are performed related to the development of biodegradable material especially in green technology. Natural fibre has seen to be the most suitable substitute for replacing the synthetic fibre due to many advantages such as low cost, variety and redundant of sources and its bio-degradability properties. By selecting the PALF, it can help in creating a new eco-friendly polymer and reducing the percentage of PALF waste. The objective of this research is to investigate the effect of PALF fibre loading to the cornstarch reinforcement in term of physical, mechanical and morphological properties. During the research, fibre loading of 5 wt%, 10 wt%, 20 wt%, 30 wt%, 40 wt %, 60 wt % and 70 wt % has been used as the sample. The composites is being fabricated using the hot-press machine. Testing of the composite are divided into two phases. First phase consist of physical and mechanical testing while the second phases consists of morphological analysis. The result from the physical testing, the value each physical properties; density, water absorption and moisture content shows that these properties are affected by the percentage, wt%, of PALF fibre loading. The mechanical testing result shows that PALF with 30 wt% has the highest reading for both tensile and flexural strength. For morphological analysis, composite sample of 30 wt% PALF fibre loading did not has gap between matrix and fibre .For this research, it can conclude that, 30 wt% of fibre loading is the most optimum fibre loading for 3cm length PALF compared to other composition ratio. Further study on characteristic of cornstarch as matrix is recommended in order to analyse the reaction of the matrix and fibres.
