The Given

Pultruded Kenaf Fiber Reinforced Unsaturated Polyester Composites (PKRC) was produced successfully using pultrusion technique at 70 wt% of fiber loading. Kenaf fiber 1400, 2200 and 3300 tex were used to produce PKRC with and without surfacing veil (SV). The aim of this study was to compare the properties of PKRC with and without SV after 200 days of natural weathering exposure. For natural weathering exposure study, PKRC 1400 specimen absorbed the least moisture followed by 2200 and the highest was 3300 tex. PKRC with SV showed lower moisture uptake than PKRC without SV in all the given environments.

In this work Tribological property of luffa fiber reinforced unsaturated polyester composites are carried out. The composites were fabricated using the compression moulding technique with optimum pressure of 150Mpa. The fabricated specimens were cut as per the ASTM standard of the wear test and ASTM G99 as followed for the entire testing of the wear. In this work, the applying load and velocity of the rotating disc was considered as a process parameter. The fiber loading was taken for the specimen to be fabricated as 30%. The test on the specimen was conducted for 10N, 20N, 30 N and velocity of 1m/s, 2m/s, 3m/s respectively. The result shows that coefficient of friction increase when increases in sliding distance..

<p>Natural fiber reinforced composites is one materials potentially developing in Indonesia. One of biggest problem with composites specimen is its void. One properties to find out void of composites is composites density value. The objective of research is to investigate the effect of fiber alkali (NaOH) treatment and microcrystalline cellulose (MCC) addition on density value of cantala fiber reinforced unsaturated polyester composites. Firstly, cantala fibers was submerged into alkali (NaOH) 6% solution for 0, 3, 6, 9, and 12 hours. Furthermore, the fiber was washed using acetid acid and then using clean water to reach pH 7. Thereafter, cantala fiber was dried in the oven for 10 hours at temperature 60<sup>0</sup>C. Composites was composed of cantala fiber, unsaturated polyester polymer matrix, and microcrystalline cellulose according to the composition with volume fraction 30%. Composites was casted using compression molding method with compressive strength of 10 MPa for 12 hours. All specimens of composites undertake post cure for 2 hours at 60<sup>0</sup>C. Density test was conducted using densimeter by calculating the density of composites in the air and the water. The result of research showed that the longer the alkali treatment time and the more addition of microcrystalline cellulose (MCC) filler, the higher is the composites density. The higher density value of cantala fiber reinforced unsaturated polyester is alkali treatment 6 hours, which was 1.223 gr/cm<sup>3</sup>.</p>

Counterface Roughness

This study examined the optimal abrasive wear performance of kenaf-reinforced polymer composite under different sliding conditions. Three different fiber loadings i.e. 43.05, 49.30 and 55.33 vol.% of kenaf fiber was reinforced into a polyester resin using the pultrusion technique. Optimal responses of wear rate and average coefficient of friction (COF) for kenaf fiber-reinforced polyester composites, based on different levels of control factors (fiber loading, applied load, counterface roughness and sliding speed) were determined by the Taguchi Design of experiment (DOE) with L9 (34) orthogonal array and Analysis of variance (ANOVA) methods. The wear behaviour of kenaf fiber-reinforced composites were investigated using DUCOM pin-on-disc tester with three levels of applied loads (10-30 N), sliding speeds (0.42-1.3 m/s) against different grit sizes of silicon carbide abrasive papers (average grain size~2.2-25.2 μm) under dry sliding condition. The optimization of S/N ratio and degree of significance of the control variables to minimize the wear rate and average COF of kenaf fiber-reinforced polyester composites was carry out. The results showed that the counterface roughness is the most significant factor in affecting the wear rate, followed by applied load, sliding speed, and fiber loading. For average COF, the fiber loading is the most significant factor followed by applied load, sliding speed and counterface roughness.
