& Akanegbu, H. A. Thermo-mechanical properties of unsaturated polyester reinforced with coconut and snail shells. This linear hydrocarbon resin is the lightest polymer among all commodity plastics. Statistical analysis on impact strength is represented by ANOVA (Table 4) and Pareto chart (Fig. These proportion yielded 14.4, 29.2, 47.0, and 53.4% improvement in flexural strength respectively, with respect to pure PP41. In the present investigation, the presence of KF in mix 2 composites reflected a consecutive rise in flexural strength with fiber loading which occurred on the dint of fiber-matrix chain network formed, coupled with enhanced adhesion between KF and PP matrix (Fig. Figure12f shows that kenaf fiber at 10 wt% and particulate snail shell at 4 wt% respectively showsoptimum combined properties.

Meanwhile, the Pareto chart detected that B, AB, and A are in the order of the significant parameters (Fig. World J. The mechanical properties were assessed and the result revealed progressive appreciation in tensile, impact, and flexural strengths. The reason for this is stress concentration as a result of fiber entanglement and particulate agglomeration between fibers as revealed in Fig. 1b), were collected, oven-dried at 50 C for 2h. 25m size was adopted on account of observations noted in Udhayasankar et al.21. Sci. https://doi.org/10.1177/0731684407086506 (2008). The infuse of 5, 10, 20, and 40 wt% KF in mix 10 composites led to 13.3, 21.7, 12.8, and 3.7% depreciation in strength. 6(60), 110. Sci. Adediran, A. 12b, the combination of 10% KF and 10% PSS yielded optimum impact strength. Figure3eh depict the mix 5 composites containing 5 wt% of the particulate.

These classes of material find application in various aspect of engineering and the choice are based on their properties. Taguchi optimization revealed an optimum mix proportion of 4 wt% PSS/10 wt% KF. Treated fiber (Fig. Taguchi optimization revealed that the collage of 4 wt% PSS and 10 wt% KF presented optimum mix for hybrid bio-PP composite. The poor performance of PSS on tensile strength is reported by Okafor et al.62 in which 5, 10, 15, 20, and 25 wt% led to the progressive decrease in strength associated with possible stress concentration at particulate/matrix boundary. Chelliah, A. J. Adhesi. Meanwhile, tensile strength was also improved with 34.80.5MPa as compared with that of PP (32.60.3MPa). Husseinsyah, S., Amri, F., Husin, K. & Ismail, H.

The result of tensile strength against KF/PSS is as presented in Fig. In this paper, we wanted to improve the PP/high density polyethylene (HDPE) impact strength by increasing the compatibility of PP/HDPE with gamma irradiation process that the un-irradiated ones were also used for comparison. These features serve as points of stress concentration eventually reducing the strength of the materials. >> Browse among more than 13 000 commercial grades by 300+ suppliers to find your perfect PP plastic. developed composite in this study showed better performance than their counterpart reinforced with hydroxylapatite and chitosan which are mostly used in reinforcement of biopolymers. https://doi.org/10.1002/vnl20268 (2011). Kenaf fiber dosage of 5, 10, 20, and 30 wt% in the presence of 2 wt% PSS demonstrated uptrend in impact strength; yielding 11.1, 28.3, 38.6, and 46.4% upgrade respectively relative to the value of pure PP. In this study, we examined the differences in the tensile strength and drop-weight impact response between polypropylene reinforced with flax fibers and that reinforced with pinewood short fibers, as both fibers differ in composition (cellulose, hemicellulose, and lignin) and . In the Charpy impact test, the impact strength for PP homopolymer was higher than those of the two PP/PE blends at both 20 and 0C. Polypropylene may be used to manufacture single layer films or as a component in multilayer films via both cast and blown film processing. Studies from Onuegbu and Nwanonenyi19 examined the mechanical properties of PP by adding pulverized groundnut husk at 2, 4, and 6%. Simultaneous Improvement in the Tensile and Impact Strength of Google Scholar. CAS Further observation revealed that 25m treated coir particles performed optimally. Surface treatment of kenaf fiber revealed a rough surface of the fiber occasioned on account of the removal of wax and impurities. Flexural strength was enhanced by admix of 5 and 10 wt% KF even as further addition of 20 and 30 wt% KF led to a depreciation in strength. Water Absorption. Mater 19(2010), 91106. Rep. 6(24326), 111.
