Effect Of Silane Coupling Agent On Inflorescence / Crab Shell Composites

Abstract

The treatment of inflorescence fiber and crab shell particles with silane coupling agents is an effective method to enhance their compatibility and interaction with polymer matrices in composite materials. Silane treatment reduces the hydrophilicity of both inflorescence fiber and crab shell particles by reacting with hydroxyl (-OH) groups on the surfaces. This creates a more hydrophobic interface, improving adhesion to polymer matrices. The thermal decomposition temperature of the treated fibers/particles increases due to the removal of weak surface components (like hemicellulose or impurities) and better fiber-matrix bonding. SEM imaging often reveals a smoother interface between the matrix and silane-treated fillers compared to untreated ones.

Specification

Description:The effects of silane coupling agent treatment on inflorescence fiber and crab shell particles, focusing on the changes in their physical characteristics. Silane treatment is a surface modification process that enhances the compatibility of these materials with polymer matrices by chemically altering their surfaces. The treatment reduces hydrophilicity, improves thermal stability, and increases dimensional stability by reducing moisture absorption. Additionally, it enhances mechanical properties like tensile and flexural strength due to better interfacial bonding and stress transfer.
The process modifies the microstructure of the materials, often removing amorphous substances and increasing the crystallinity index of the fibers. It also introduces functional groups that promote covalent bonding with the polymer, thereby improving the composite's overall performance. The treated materials show improved thermal stability, mechanical strength, and interfacial adhesion, making them suitable for advanced applications in eco-friendly and high-performance composite materials for automotive, construction, and marine industries.
This study underscores the potential of silane-treated natural reinforcements as sustainable alternatives in composite fabrication
