Abstract
The purpose of this study is to improve tensile behavior of no-impregnated (dry) carbon fiber sheets. First, tensile tests of dry carbon fiber sheets with different spans are carried out and it is confirmedthat the tensile strength is only about 30-40% of that of carbon fiber reinforced polymer (CFRP) sheets. Then, two countermeasures by means of partial impregnation with epoxy resin and hybridization with PBO (Poly-para-phenylene-benzo-bis-oxazole) fiber sheets which present high performance in energy absorption are examined to improve the tensile strength of dry carbon fiber sheets. Through a series of experiments, it is realized that the tensile strength ratios of dry carbon fiber sheets with a combination of the two countermeasures to CFRP sheets can be enhanced into 60-70%.
