Experimental evaluation of bamboo fiber/particulate coconut shell hybrid PVC composite

Abstract

Bamboo fibers (BF) treated in 1.3 Molar NaOH and particulate coconut shell (PCS) sieved to − 45 µm were incorporated into polyvinyl chloride (PVC) matrix towards improving the properties of PVC composite for ceiling boards and insulating pipes which sags and degrade with time needing improvement in properties. The process was carried out via compression moulding applying 0.2 kPa pressure and carried out at a temperature of 170 °C. Composites developed were grouped according to their composition. Groups A, B, C, and D were infused with 2, 4, 6 and 8 wt% PCS at constant amount, respectively. Each group was intermixed with a varying proportions of BF (0–30 wt% at 5% interval). Tests carried out on the samples produced revealed that the yield strength, modulus of elasticity, flexural strength, modulus of rupture were enhanced with increasing BF proportion from 0 to 30 wt% BF at 2 wt% constant PCS input. Thermal and electrical properties trended downward as the fiber content reduced even as the hardness was enhanced with PCS/BF intermix which was also reflected in the wear loss index. Impact strength was highest on the infix of 4 wt% PCS and 15 wt% BF. Compressive strength was better boasted with increasing fiber and PCS amount but 8 wt% PCS amounted to depreciation in trend. It was generally observed that PCS performed optimally at 2 wt% incorporation while beyond that resulted in lowering of strength. Blending of the two variable inputs; 0–30 wt% BF and 2 wt% PCS presented better enhancement in properties.

Preparation and ultrasonic characterization of modified epoxy resin/coconut shell powder biocomposites

“…Salmah, et al 3 reported the same relationship between PLA and treated CSP with AA. Similarly, the agglomerations that reduce the values of elastic constants of materials were reported in the research carried out by Adediran, Akinwande, Balogun, Olasoju, and Adesina 64 . In addition, Olumuyiwa, et al, 10 reported a decrease of homogeneity between the CSPs and the matrix system with an increase in the CSPs content.…”

Mechanical and optimization studies of polypropylene hybrid biocomposites

“…Additionally, hybrid polymer composites of fiber and particulate fillers blend had been a subject of investigation for years; as investigated by Balaji et al 29 which entailed a study on bagasse fiber/coconut shell hybrid biocomposites. On the other hand, hybridized polypropylene with coir fiber and yam peel particulate as reported by Adediran et al 30 , showed an improvement in impact strength as well as tensile and flexural properties. In Adeosun et al’s work 31 , hybrid polyester composite with the blend of coconut and snail shell particulate in unsaturated polyester was reported.…”

Optimization of Flexural Strength of Recycled Polyethylene-terephthalate (PET) Eco-Composite using Response Surface Methodology

“…Results had shown that with increasing rPET proportion, the properties are reduced owing to degradation of the recycled plastic during the process [11]. Based on records of achievement of reinforcing additive in property enhancement of base-polymer [12,13], their incorporation into rPET/vPET matrix should be studied for property enhancement of the blend.…”
