A study on Impact Absorbing Performance of CFRP Crash Box

(Fundamental Consideration on Unidirectional Continuous Fiber Laminate Composition)

Abstract

In recent years, there has been a significant increase in the widespread utilization of carbon fiber reinforced plastic (CFRP) due to its remarkable specific strength and rigidity. This material finds extensive application in various mechanical products, particularly in components that experience minimal or static loads, such as outer panels and structural elements. Moreover, researchers have been investigating the impact response of CFRP and have discovered its potential for exceptional shock absorption properties. By altering the orientation of carbon fibers and adjusting the number of layers, the structural strength of CFRP can be customized according to specific requirements. Based on these characteristics, the researchers conducted a drop weight test on test specimens with varying layer configurations to elucidate the shock absorption performance of the material.
