Comparative Study of the Effect of Basalt Fiber on Dynamic Damage Characteristics of Ceramics Cement–Based Porous Material

Abstract

Cementitious materials, ceramic aggregates, and fiber are used as basic materials; ceramics cement–based porous material (CCPM) and basalt fiber-reinforced ceramics cement–based porous material (BFRCCPM) are prepared on the basis of Closest Packing Theory. After the tests, the internal relation between the average change rate of incident energy and the physical essence of the ensemble damage modes is discussed, and the change law of energy is probed. BFRCCPM’s compression energy properties during the dynamic deformation damage process are analyzed, and based on that, the effect of basalt fiber on the dynamic damage characteristics are studied. Results show that the damage level and energy absorption of CCPM and BFRCCPM get more serious or increase with the average change rate of incident energy; the damage level of BFRCCPM is obviously lower than that of CCPM. Moreover, BFRCCPM possesses better energy absorbing properties than CCPM. This advantage is more obvious when the average change rate of incident energy is very high; the impact-damage resistance of CCPM and BFRCCPM increases with impact strength. The impact-damage resistance of BFRCCPM is stronger than that of CCPM. Thus it can be seen that basalt fiber can prevent microdamages from developing and evolving, which can enhance the impact-damage resistance of CCPM.
