摘要：

This paper reports on the properties of microscale water hyacinth fiber pulp (WHF) filled tapioca starch biopolymer (TSB) composites. The volume fraction of WHF in the TSB matrix is varied, that is, 1%, 3%, 5%, and 10%. A casting method is used for making sample films of the biocomposites. Scanning electron microscopy (SEM) of the fracture surface of the biocomposite for the tensile samples displays good fiber distribution in the matrix, and interface bonding between WHF and TSB. The 10% fiber biocomposite deliveres the highest value of tensile strength (TS) of 6.68MPa, and tensile modulus (TM) of 210.95MPa; however, this combination also has the lowest fracture strain of 7.30%. In this case, there was 549% improvement of TS and 973% of TM in comparison to TSB. The biocomposite with 10% WHF content also showes the highest thermal resistance and the lowest moisture absorption. It shows potential for future commercial applications.
