Energy Absorption of Basalt Filament Wound Rectangular Tubes: Experimental Study

Abstract:

The objective of this study was to determine the energy absorption of basalt filament wound rectangular tubes under crushing test. Basalt fibre gained a lot of potential in various application due to low cost of this material together with its capability to breaking the domination of e-glass as a reinforcement material. Coupon tensile and axial compression (crushing) test were performed to investigate the strength and energy absorption performance of basalt filament wound rectangular tubes. Both test have been conducted using [±70⁰]₃ winding angle of sample configuration and comparison have been made in coupon test in which the basalt sample shows 8.7% higher than e-glass while produced opposite results in modulus of elasticity. Crushing test was performed in 25mm displacement with different loading rate which are 5, 10 and 15mm/min. The results obtained from three different conditions were compared showing a higher energy absorbed in the lower loading rate. The comparable crashworthiness of basalt suggest possible applications such as automotive industry which is requires a good energy absorb materials in some particular components.
