Characterisation of Hand-Cast Polysiloxane-Silica Sheet Composite

Abstract

The study investigates the effects of various contents of rice husk silica (RHS) on mechanical properties of polysiloxane (POS) sheet composite. The polysiloxane sheet composites filled with 5wt%, 10wt%, 15wt% and 20wt% of RHS were fabricated using casting technique at room temperature. The polysiloxane sheet reinforced RHS (POS-RHS) composites were characterised using thermogravimetry analysis (TGA), Fourier Transformation Infrared Spectroscopy (FTIR) and tensile test to determine the thermal and mechanical properties. It was found that the RHS as filler in polysiloxane is improvement in mechanical properties and the curve degradation of POS and POS-RHS are similarly. By using FTIR was shown the affect of Si and O bonding from RHS as filler.
