Abstract

To study the hybrid effect of hybrid fiber sheets and its constitutive relation,uniaxial tensile tests of 1CnB(1 layer of CFRP sheet hybrid with n layers of BFRP sheets) hybrid fibers sheets with different hybrid ratio and two mixed modes are studied in this paper.The results show that when the volume ratio of BFRP is low,its damage mode still manifests in the form of linear elastic.But with the improving of the BFRP /CFRP ratio,the rupture strain become higher and higher,constitutive curve begins to showyield point elongationand the phenomenon of multi-level rupture;failure process is more gentle and with a clear sign,showing a certain degree of ductility and the shortcoming of brittle fracture of single fiber is overcome.The hybrid mode also has impact on the fiber hybrid effect,and the sandwich mixed mode is better than the outer layer mixed mode.Based on the test results,a formula of hybrid effect factor is put forward by regression analysis.Formula of critical volume ratio is derived,and further the constitutive relation of hybrid fiber is proposed.
