Understanding the effects of altering impact velocities and temperatures on basalt textile: An experiment approach

Abstract

Basalt textiles are finding new applications in several industries due to less complicated composition, high elastic modulus and remarkable tenacity. Present study examines the low-velocity impact (LVI) performance of basalt textile at four distinct incidence velocities: 1, 2, 3, and 4 m/s. The effect of changing external temperatures, particularly −50, 0, 25, and 100 °C, are also investigated. To evaluate the low-velocity impact response, two types of surface coated basalt textiles were tested (i) single-layer basalt textile or SLBT and (ii) double-layered basalt textile or DLBT. Different parameters such as first-crack load, deflection at first-crack, peak impact load, ultimate deflection, energy absorbed at peak load, total energy absorption are considered and compared. The temperature influence factor (TIF) was measured and compared with the reference sample at room temperature to assess the influence of external temperature variations on SLBT. The cumulative failure probability of textile under LVI at varied loads and temperatures revealed a substantial variation in mechanical performance. The failure patterns and microscopic morphologies of fractured textiles demonstrated that two layers of textiles give superior damage resistance under LVI condition.
