Abstract

This present study investigates the role of adding sugarcane bagasse biosilica (SBB) fine particle on Opuntia dilleniifibre (ODF)-reinforced epoxy resin composite and its mechanical, thermal and laminar shear strength properties. In this study, the biosilica particles were prepared from Indiana sugarcane bagasse via thermo-chemical process. The fibre and particles were silane surface-treated (SST) using 3-aminopropyltrimethoxysilane via acid hydrolysis process. Hand layup was used to create the composites, which were then post-cured at 120 °C for 48 h. The composites were characterized using ASTM standards in order to evaluate the mechanical, thermal and laminar shear strength properties. The tensile strength of SST fibre and particle produced the highest strength of 178 MPa for 40 vol.% of fibre and 2 vol.% of particle in epoxy resin. Similarly, the SST fibre and particle retained high thermal stability than as-received fibre and particle in the composite. The laminar shear strength of SST fibre shows the highest value of 33 MPa against shear load. The SEM morphology shows highly adherence surface between SST fibre and resin. Thus, in the process of making biocomposites using plant-based fibres, the silane treatment is mandated in order to achieve high performance.

Abstract

In this study the experimental investigation of mechanical behaviour of Multi-Walled Carbon nanotubes (MWCNTs) and Aluminium Oxide (Al2O3) reinforced with EGlass/ Epoxy nanocomposites at 0.5%, 1.5% and 2.0% of weight rated with 225 GSM, 300 GSM and 450 GSM glass fibres were studied. Test specimens were prepared at the standardof ASTM D638 for tensile specimen ASTM D256 for impact specimen. Testspecimens were prepared at the ratio of MWCNTs: Al2O3 is 1:4. 1.5 wt. % of Multi- Walled CNTs filledE-Glass/Epoxy nanocomposites showed improved mechanical properties than glass fiber reinforced epoxy composites.450 GSM reinforced glass fiber epoxy composites containing 1.5wt. % of MWCNTs improved 36.27 % of higher tensile value and 28.57 % of impact value than the glass fibre reinforced epoxy composites. 225 and 300 GSM reinforced glass fibre epoxy composites with 1.5 wt. % of MWCNTs composites also has improved tensile and impact value than glass fibre reinforced epoxy composites. But, overall 450 GSM reinforced fibre nanocomposites showed enhanced mechanical properties than the other GSM reinforced nanocomposites. This proves Multi- Walled Carbon Nanotubes is a successful reinforcement for E-Glass/Epoxy matrix and it improves its properties and performance. [ABSTRACT FROM AUTHOR]
