Mechanical behavior characteristics of hybrid composites with non-woven carbon tissue are investigated under static tensile loading. This hybrid laminate consists of unidirectional prepreg and non-woven carbon tissue, made by inserting non-woven carbon tissue between prepreg layers. Static tensile test of CFRP and hybrid laminates are carried out. Chord shear modulus and 0.2%-offset shear strength of a CFRP laminates are obtained and compared with those of the hybrid laminates. The hybrid laminates, seem to be effective to improve the tensile characteristics. The fracture surfaces of the specimens are observed with SEM and an optical microscope, and the failure mechanism is discussed.
