This study presented the effect of different fibre length and seawater treatment on mechanical properties of the fabricated composites. The composite was reinforced with fixed 30wt.% of fibre loading. Sugar palm was treated using sea water for 30 days and have been cut into three different lengths by 5cm, 10cm and 15cm. The mechanical properties of the untreated and treated fibre with different fibre length composites were characterised includes tensile test and flexural test. Treated sugar palm fibre composites with 15cm fibre length exhibited higher tensile strength at 18.33 MPa. However, it shows the lowest value for the tensile modulus at 4251.96MPa. The flexural strength shows an increasing trend as the fibre length increased up to 15cm and the maximum flexural strength was exhibited by treated sugar palm fibre with 5 cm at 80.80MPa.Effect of Fibre Length and Sea Water Treatment on Mechanical Properties of Sugar Palm Fibre Reinforced Unsaturated Polyester Composites

This research was conducted to evaluate the potential of sugar palm residue as a raw material to produce the new green composites. The physical properties of sugar palm fibre reinforced unsaturated polyester composites from different part which are sugar palm frond (SPF/PE), sugar palm bunch (SPB/PE), sugar palm trunk (SPT/PE) and black sugar palm fibre (ijuk/PE) were studied. Samples were submerged in distilled water for 24 hours. The water absorption and thickness swelling were investigated in order to determine the dimensional stability of the composites. It is found that SPF/PE showed the higher value of water absorption and thickness swelling which are 1.57%, and 1.56% followed by SPB/PE (1.35%, 1.11%), ijuk/PE (0.65%, 0.76%) and SPT/PE (0.39%, 0.50%). Generally, this investigation is valuable for researchers in order to evaluate the potential and some possible application of sugar palm residues as a new natural composites product.

The aim of this study is to investigate the effect of impregnation pressure on physical and tensile properties of sugar palm (Arenga pinnata) fibres. The fibre was impregnated with phenol formaldehyde (PF) and unsaturated polyester (UP) with different impregnation pressures (1000, 900, 800, 700, 600 and 500 mmHg) at constant impregnation time of 5 min. Significant improvement in physical properties was observed due to reduction of moisture content (MC) and water absorption (WA) after being impregnated from 1000 to 500 mmHg while PF-impregnated fibre was showing more superior. Improvement in mechanical properties was also observed after being impregnated where much better tensile properties and toughness were found at UP-impregnated fibres while PF-impregnated fibres were found to be very much lower in toughness. This study concluded that in order to obtain a high toughness and better physical properties of sugar palm fibre, the fibre should be impregnated with UP resin with impregnation pressure of 600 mmHg.

This investigation is done to select the best composite on bending strength and stiffness derived from different parts of sugar palm fibre reinforced unsaturated polyester composites. Sugar palm tree is one of the most popular natural fibres. The fibre was obtained from the sugar palm tree and mixed with unsaturated polyester (PE). All of the composites are labelled as SPF/PE for sugar palm frond composite, SPB/PE for sugar palm bunch composite, SPT/PE for sugar palm trunk composite and ijuk/PE for black sugar palm fibre composite. The bending strength and stiffness tests were done according to ASTM D 790-(2000). The higher value of bending strength and stiffness obtained by SPT/PE which is 41.906 MPa and 3.363 GPa respectively followed by SPF/PE (38.906 MPa and 3.001 GPa), SPB/PE (35.168 MPa and 2.749) and ijuk/PE (33.742 MPa and 2.424 GPa)

The aim of this paper was the effects of different fiber size on tensile and flexural properties. Preparation of thermoset unsaturated polyester reinforced with particle Bertam (Eugeissona tristis) was done by hand layout method. Bertam/polyester composites containing Bertam fiber of different sizes, i.e., 15, 120 and 284 μm were prepared. For each composite, eight specimens were tested to evaluate the mechanical properties. It was found that composite reinforced with Bertam having the shortest fiber length, i.e, 15 μm showed the highest tensile and flexural modulus, which were 204.14 MPa and 1826.78 MPa, respectively.
