Abstract
The effect of thermoset resin type and geothermal silica loading on the mechanical properties and water sorption of geothermal silica/thermoset composites are determined. Thermoset resin type has significant effect on the flexural strength, hardness, water uptake and weight loss of the composites. Composites based from isophthalic polyester resin has higher flexural properties and hardness and lower water uptake and weight loss over other types. Geothermal silica loading has significant effect on the hardness and water uptake of composites. The highest hardness and water uptake were observed at 5%w/w geothermal silica loading.
