Acrylonitrile butadiene styrene (ABS) resin has been applied as light and inexpensive materials. In order to reduce the cost, the ABS resin covered with high strength CFRP sheets (CFRP/ABS/CFRP) has been proposed. Concequently, small dose of homogeneous 100 keV class EB-irradiation perfectly improved the a_<uc> of CFRP. The maximum a_<uc> value at mid P_f (0.50) for the CFRP/ABS/CFRP is approximately equal to or less than that for CFRP. Therefore, the maximum a_<uc> value at mid P_f (0.50) after 0.30MGy irradiation for the CFRP/ABS/CFRP was approximately equal to that for CFRP. It was also about 21.4% higher than that of these CFRP before treatment. The use of ABS resin as the core reduced other mechanical properties of tensile and bending, whereas the price of CFRP was apparently higher than that of ABS resin. Thus, it is possible that the sandwich structural composites of CFRP/ABS/CFRP could be utilized for daily articles.
