Abstract

Biocarbon in hemp composite alters its physical, thermal, and mechanical properties. Biocarbon from the spruce pellets was obtained at 450 °C through pyrolysis. 20 wt.% and 50 wt.% of biocarbon (below 53 microns particle size) were added to produce hemp fibre reinforced epoxy composite samples. The biocarbon in composite samples increased the glass transition temperature of the hemp-epoxy composites. Hemp fibre content is directly proportional to the resulting material’s impact energy. The impact energy of the hemp composites without biocarbon was 15 J/m, composite with 20 wt.% biocarbon was 10 J/m, and the composite with 50 wt.% biocarbon was 9 J/m. The hardness values of the composites without biochar, with 20 wt.% biochar and 50 wt.% biochar were 5.6, 16.3, and 23.7 HRLS, respectively. At saturation level, composite with no biochar was higher than the other two composites. 50wt.% biochar containing composite showed the least water absorbing behaviour.
