Open-Hole Compression Test of Composite Material

Introduction

Carbon fiber reinforced plastic (CFRP) has gained attention due to their strength and low weight, and have quickly been adopted for use in aeronautics and astronautics. CFRP has excellent strength characteristics in terms of specific strength and high rigidity, but lose much of their strength when a cutout is made. Consequently, composite materials used in aeroplanes must be evaluated by tests that use specimens with a hole cut out of their center. We performed open-hole compression testing of a CFRP according to ASTM D6484.
