Characteristic of thermoplastics corn starch composite reinforced short pineapple leaf fibre by using laminates method

Abstract

In recent years, the increased demand of biodegradable polymers has sparked the research interest in the development of alternatives to conventional polymers. As such, starch considerably one of the best substitutes to the non-degradable polymers owing to its advantages. The main purpose of this study is to investigate the mechanical, physical and environmental characterization of bio-composites, which is in this case the thermoplastic corn starch (TPCS) reinforced with a 2 mm length of pineapple leaf fibre (PALF). The selection of different weight percentages in the range of 20 to 60 weight percentage (wt.%) of PALF contents were applied in this work. The mixtures of TPCS with different wt.% of PALF were made by using a hot compression moulding at 165 °C for 15 minutes. Several testing has been performed to determine the bio-composites characteristics. The results show that by incorporating 40 wt.% loading of PALF, the tensile and modulus strength has increased to the maximum. It is also seen that there is an inverse relationship between the moisture content and the wt.% loading of PALF. However, the water and moisture absorption show a direct relationship with wt.% loading of PALF. Meanwhile, the soil burial decreases when the wt.% loadings of PALF increase while the results for water solubility suggest vice versa. It is also found that the TPCS with 40 wt.% of PALF have a good miscibility between matrix/fibre in the bio-composites.

State of Knowledge on Starch as an Alternative Solution to Petrochemical Resources—A Review

“…The results show that for an addition by weight of cassava bagasse relative to the mass of starch of 3%, 6% and 9%, the physical parameters such as thickness, water content and rate of water absorption of composites increases with the addition of fibers; on the other hand, the density and the degree of solubility decrease. These results are similar in most publications that make the same observation [1] [8] [25].…”

“…A composite film can be defined as a combination of several immiscible materials of intrinsic characteristics, the mixing of which produces a material of improved performance of small thickness, which can be in the order of less than 3 mm. Film composite is used nowadays in several industries such as food packaging, production of electrical and electronic equipment [1].…”

“…Plastic is used nowadays in several industries such as food packaging, production of electrical and electronic equipment [1]. Plastic production was 299 million tonnes in 2013 and is expected to increase by 3.9% per year [2].…”

“…TPS has poor mechanical and water barrier properties and must be reinforced with mineral, organic fillers or fibers [6] [7]. This is how thermoplastic starch (TPS) has been reinforced with Kenaf fibers [8], banana leaves [9], cassava fibers [10], kaolinite [7], pineapple leaf fibers [1] chitosan [11], two-and three-dimensional loads [6].…”

“…percent to have good plasticization, this is justified through the percentage of glycerol used in the work[1] [8][9] [25]-[29].…”
