Abstract

The study investigates the vibration and mechanical properties of rice husk silica (RHS) in enhancing the properties of Polydimethylsiloxane (PDMS). The PDMS/RHS composites panel were fabricated by using casting technique and cured at room temperature. PDMS panels were filled with 2 – 12 wt% of RHS. Vibration analysis of PDMS/RHS composites panel were guided by ISO 8662 standard in evaluation of hand arm vibration for hand grinder machine. The vibration exposure analysis showed that application of PDMS/RHS as a vibration absorber successfully decreased the vibration exposure to 46%. Tensile properties analysis conducted using ASTM D412 standard showed that the PDMS/10 wt% RHS properties increased to 9.6% compared to PDMS without RHS. Thus it is concluded that the addition of RHS had improved both properties of PDMS. RHS has successfully acts as a reinforcement when load is applied to the panel and during vibration exposure, RHS has acts as an absorber and distributed the vibration.
