Publisher: | Pamukkale Univ | Abstract: | In this study, crushing and energy absorption behavior of carbon nanotube (CNT) reinforced glass fiber/epoxy (GFRP) and carbon fiber/epoxy (CFRP) composite tubular structures has been investigated. The study consists of two main parts. First part deals with the experimental studies. At this stage, functionalized multi-walled CNT added (at weight percentages of 0.1; 0.2; 0.3; 0.5; 1; 2%) and additive free GFRP composite plates were produced using hand lay-up method and tension, compression and shear tests were carried out to determine mechanical properties of the composite materials. As a result of these investigations, 0.5% CNT addition is determined to be most suitable rate for the composite in terms of tension, compression, and shear strength. The second part deals with the numerical studies. At this stage, quasi static crushing and energy absorption characteristics of circular and square cross-section GFRP and CFRP tubes were investigated numerically using the determined mechanical properties in a commercial finite element based software (ABAQUS). The mechanical properties of CFRP tubes were taken from the existing literature. As a result of numerical studies, the specific energy absorption capacity of circular CFRP tubes was found to be most efficient compared to the other tubes. | URI: | https://doi.org/10.5505/pajes.2021.68047 https://search.trdizin.gov.tr/yayin/detay/520119 https://hdl.handle.net/11499/46146 |
