Compressive Behaviours of Oil Bean Shell and Wood Particulates/ Epoxy Composite Board

Abstract

The compressive behaviours (compressive strength, compressive energy, Young’s modulus, failure time, and compressive strain) of epoxy composite board, reinforced with oil bean pod shell particulates (OBPS) and mahogany timber saw dust (SD) were investigated in this research. The samples were prepared with five different fillers (OBPS and SD) percentage (10, 15, 20, 25 and 30 vol.%) in the ratio of 1:1. Both filler materials where treated with 5(w/v)% Sodium hydroxide solution to enhance their mechanical properties. All the composite samples were tested according to ASTM standards, by using the Universal Testing Machine. Results obtained from the research showed that fillers loading had significant (P ≤0.05) effect on all the compressive behaviours investigated. In addition, the results showed that the fillers significantly improved all the compressive parameters. The compressive strength of the composite increased from 14.54 to 48.19 MPa, as the fillers loading increased from 10 to 30 wt.%, while the Young’s modulus increased by 49%. The compressive energy increased from 21.4 to 146 Nm. Data gotten from this research can be useful in the production of composite boards for engineering applications.

Effect of Green Admixtures on the Mechanical Properties of Concrete Composite

“…The results revealed that the cassava starch, periwinkle shells and sawdust influenced the compressive strength of the concrete produced. It was noted that the compressive strength of the concrete non-linearly, as the cassava starch volume increases; such as the cassava starch increased from 0% to 2.5, Sample 1 (control sample) compressive strength increased from 25.2 to 28.4 MP; Samples 2, 3, 4, 5 and 6 compressive strength increased from 23.5 to 25.3 MPa, 19.9 to 21.2 AJINAS, 3 (2) Akwenuke and Edafiadhe, 2023 matrix (paste); hence creasing voids within the concrete, which can result in the development of concrete with lower compressive strength (Ettu et al, 2013;Edafiadhe et al, 2019).…”

Influence of Treatments on the Mechanical Properties of Epoxy Resin Hybrid Composites Reinforced with Pineapple Fiber and Snail Shell Particulates

“…Composites manufactured from natural fibers and fillers are being rigorously researched as substantial alternatives to synthetic composite reinforcement materials. Bio-based composites are gaining industrial attention, as these materials are widely used in a variety of industrial applications (Sivakumar et al, 2017;Asim et al, 2018;Edafiadhe et al, 2019;Obukoeroro and Uguru, 2021;Cionita et al, 2022). One of the significant advantages of natural materials is their biodegradable nature; which contrasts with synthetic materials, as they persist in the environment for much longer durations.…”

A comparative study on the tensile properties and environmental suitability of glass fibre/raffia palm/plantain fibres hybridized epoxy bio-composites

“…Bio-composites are one of the engineering materials used in engineering applications, and their popularity is rapidly increasing due to their lightweight, eco-friendliness, availability of the raw materials and good engineering properties (Puglia et al, 2004;Fogorasi and Barbu, 2017;Esegbuyota et al, 2019). Hence, they helped to reduce the negative impact of carbon emissions on the environment, through the reduction in fuel consumption, resulting from the production of light weight vehicles (Fogorasi and Barbu, 2017;Edafiadhe et al, 2019). Most organic reinforcement materials (fibres and fillers) used in bio-composite production have been proven to have adequate mechanical and thermal properties (Mir et al, 2012), which are critical factors usually considered during material selection in the automobile industry.…”

This is because they helped to reduce the negative impact of carbon emissions on the environment, through the reduction in fuel consumption (Fogorasi and Barbu, 2017;Edafiadhe et al 2019). Zah et al (2007) stated that bio-composites involved the utilization of at least one biodegradable material during composite production.…”
