Impact Characteristics of CFRP Hat-Shaped Members According to Changes in Outer Layer under the Hygrothermal Environment

Abstract:

CFRP composite material, which is reinforced with carbon fiber, features superior heat and corrosion resistance, and these benefits enables the gradual applications on aerospace industries and sports-entertainment business. However, guarantee on superior strength and rigidity on harsh condition, such as hot moisture environment and collision load is extremely difficult. Therefore, in study moisture absorption test was conducted until complete moisture absorption in test specimen using hygrothermal heat chamber to evaluate strength degradation in CFRP composite under hygrothermal environment. As a result, the effect of moisture absorption and impact loads of approximately 50% reduction in strength are shown.
