Evidently, in mix 4 composites (4 wt% PSS), it is observed that KF loading demonstrated an uptrend in tensile strength from 5 to 20 wt%. The coexistence of 4 wt% PSS/10 wt% KF in PP matrix had an improvement of 15.2% over values on the infusion of 4 wt% PSS/5 wt% KF. The choice of polypropylene is on the dint of low cost and its availability in the Nigerian market. Intermix of 5, 10, 20, and 30 wt% kenaf fiber and 10 wt% PSS led to a reduction in compressive strength (Fig. If you find something abusive or that does not comply with our terms or guidelines please flag it as inappropriate. In comparison, mix 4 composite samples blended with 4 wt% (PSS) performed better than mix 2 counterparts (2 wt% PSS) when 5 and 10 wt% KF was infused. The control mix was produced as pure polypropylene (PP) with no KF and PSS admix. 264265, 743747. Kenaf/polypropylene composite was developed by authors Lee et al.26.

Findings from Haque et al.59, Haque et al.60, Haque and Islam61 revealed that fiber inclusion in polymer matrix up to 20 wt% ensued enhancement of tensile strength. Further addition of 30 wt% KF manifested slight depreciation in strength. Further intermix of 4 wt% PSS with 20 and 30 wt% KF resulted in a 7.0 and 17.5% reduction in strength relative to the value obtained when 4 wt% PSS and 10 wt% KF was infused; though the value was still an enhancement of 43.8 and 27.6% over pure PP. This is responsible for low performance of the mix 10 samples.
