Properties of Thermoplastic Starch/Kenaf Composite

Abstract

This paper reports on the physical and mechanical properties of the thermoplastic sago starch/kenaf fibre (TPSS/KF) composite. The composite was prepared through a compression molding technique at varying fibre contents of 0, 10, 20 and 30 wt.%, whilst the effect of the fibres incorporation was evaluated by physical and mechanical tests, as well as morphological analysis. Reduction of moisture content and denser composite were achieved with a higher fibre content. Meanwhile, the water absorption of the composite was lower than the thermoplastic with an increase in the kenaf fibre loading. Tensile testing improved strength and modulus with the increase of fibres content until an optimum was reached at 30 wt.% of fiber loading. Morphological analysis showed good wetting between the polymer matrix and fibres that provided the tensile improvement.

Physical, mechanical, and water absorption behavior of coir/glass fiber reinforced epoxy based hybrid composites

“…The reason may be due to the longer fibers tend to ball up resulting in low workability and decline in strength. The similar trend is also observed by previous researchers . As far as the effect of fiber loading is concerned, composites with 10 wt% fiber loading shows better flexural strength value as compared to 5 wt% fiber loading.…”

Processing and characterization of thermoplastic corn starch‐based film/paper composites containing microcrystalline cellulose

“…The main FTIR peaks of papers were at 3334 cm −1 (-OH), 2904 cm −1 (C stretching vibration of aliphatic groups) and 1639 cm −1 (O─H form free water contained in cellulose). 39 The FTIR spectra of TPS/paper and MCC@TPS/paper were very similar to that of paper. However, the -OH peak of TPS/paper appeared at 3335 cm −1 because, when the TPS composite films were compounded with paper, part of the melted TPS composite films flowed into the paper, resulting in a decreased bonding force between the hydroxyl groups of the TPS composite films, thus making the -OH stretching peak move to a high peak to form the weaker molecular interactions.…”

“…Furthermore, the interaction between fiber-matrix may also cause reduce the water uptake of the film. Strong interaction adhesion between the KCF and CS matrix may help to resist the water molecules from diffusing into the CS matrix [17]. De Carvalho et al [18], stated in his report that the KCF may also absorb some of the remaining glycerol within the CS matrix.…”
