Natural fibers are increasingly used as a reinforcement in fiber reinforced composite, due to their low cost, low density, sustainable availability compared to the traditional fibers. In addition, natural fibers are environmentally friendly materials. In this paper, low velocity charpy impact tests on coir, glass and hybrid coir-glass/epoxy were carried out. Hand lay-up method was used to fabricate the specimens with the dimensions of 50 mm x 10 mm x 10 mm. Impact specimens of a square, semi-circular and v-notch forms were fabricated and tested. Impact tests were conducted for a temperature range of -40°C to 40°C in intervals of 10°C. Effect of testing temperature, notch form, fibre volume fraction and span length to depth ratio on the impact energy were investigated. Failure mechanism of the fractured specimens was examined. Results show that impact energy of the composite specimens increased with increasing the temperature for the range of -40°C to 40°C. The glass/epoxy specimens with semi-circular notch form absorbed energy higher 19.22% and 26.83% than the v-notch and square notch form specimens. The impact energy of semi-circular notch glass/ epoxy specimens is found higher respectively 28.14% and 54.55% than that obtained from the hybrid coir-glass and coir/ epoxy specimens. The impact energy decreased significantly with increasing the span length to depth ratio from 6.88 to 11. The increase in the fibre volume fraction from 0.45% to 0.65% increased the impact energy of the tested specimens.
