プレス加工による難加工アラミド繊維積層材の新しい穴あけ加工法

抄録

The purpose of the present research is to develop a simple and convenient method of punching in intractable AFRP (aramid fiber reinforced plastics) laminated composites. An aramid plate is tightly restrained around the punched region as well as the bottom of the sample, and subsequently it is punched by a specially designed hollow punch. The present improved technique of press working has led to an excellent processing of intractable AFRP composites, which has never been achieved by any other technology such as water jet cutting or vibration press.
