Nowadays, CFRP composite materials are receiving much attention because of their superior mechanical properties compared to metals and their lightweight, which has contributed to the high fuel efficiency of structures. However, the compressive strength of composite materials is lower than its tensile strength. Structures like airplanes and automobile are assembled with components such as bolts, pins, etc. and the strength of these components, or notches, can degrade. In this study, the compressive strengths of notched flat specimens were compared with those of unnotched flat specimens through compression tests. Also, the compressive strengths of differently shaped structures were compared and verified with those of the specimens Korean Society for Precision Engineering and Springer-Verlag Berlin Heidelberg, 2013 CFRP (Carbon fiber reinforced plastics) nationallicence Compressive strength nationallicence Hole notch nationallicence Point stress criterion nationallicence Notch strength nationallicence C shape structure nationallicence σ y : stress of y-axis nationallicence R : hole radius nationallicence σ N : notch strength nationallicence σ N ∞ : infinite notch strength nationallicence d0 : characteristic length nationallicence Y : correction factor of finite plate nationallicence k : shape factor nationallicence Ahn Sang Graduate school of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut Hong Suk Graduate school of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut Koo Jae Department of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut Seok Chang Department of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut International Journal of Precision Engineering and Manufacturing Korean Society for Precision Engineering 14/6(2013-06-01), 1103-1108 2234-7593 14:6<1103 2013 14 12541 https://doi.org/10.1007/s12541-013-0149-0 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1007/s12541-013-0149-0 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Ahn Sang Graduate school of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut NATIONALLICENCE 700 1- Hong Suk Graduate school of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut NATIONALLICENCE 700 1- Koo Jae Department of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut NATIONALLICENCE 700 1- Seok Chang Department of Mechanical Engineering, Sungkyunkwan University, 2066, Seobu-ro, Jangan-gu, 440-746, Suwon, South Korea aut NATIONALLICENCE 773 0- International Journal of Precision Engineering and Manufacturing Korean Society for Precision Engineering 14/6(2013-06-01), 1103-1108 2234-7593 14:6<1103 2013 14 12541 Metadata rights reserved Springer special CC-BY-NC licence nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-springer
