It has passed one century since French G. Charpy proposed the Charpy impact test in 1901. Instrumented impact test recording load history during fracture has been attempted since 1920's. It has become possible to obtain various information from this method. However, succeeding development of fracture mechanics has made it also as a qualitative screening .
Therefore the present work evaluates the Charpy impact resistance of epoxy matrix composites, reinforced with 10, 20 and 30% in volume of continuous and aligned malva fibers (Urena Lobata, L).
