Nowadays, the interest in using natural fibers reinforced plastic have been increased dramatically in many engineering applications due to its distinctive properties such as low density, good Energy-absorbing capacity, and is considered environmentally friendly. In the present paper investigated experimentally the crashworthiness characteristics and corresponding energy-absorbing capability of different geometrical shapes under quasi-static loading of natural tubular jute mat/epoxy composite structures. The purpose is to determine the appropriate design of natural compounds, which can provide the potential to substitute conventional structures currently in use. Two different geometrical shapes (corrugated and circular tubes) were fabricated by a combination manual lay-up and vacuum-bagging moulding techniques, specimen thickness (2, 3 and 4 laminate plies), tulip triggering and 100mm in length, and then the post-curing has been conducted on graded temperature treatment. The influence of cross-section shape, number of laminate plies, and temperature treatment on crashworthiness characteristics under quasi-static loading were examined and discussed. From this unique study, Laboratory results indicate that most of the specimens failed in a stable and progressive manner. However, the corrugated cross-sectional shapes with three layers are considered optimum design in terms of energy-absorbing, peak load, average load, and crushing efficiency for crashworthiness tubes application
