A unit cell model based on a unit cell of plain weave carbon fiber/carbon nanotube/phenolic resin composite is present in this research. To simulate the effects of CNTs for the composites, Mori-Tanak a theory was used to calculate the mechanical properties of CNTs reinforced phenolic resin material. These results were adopted for unit cell model to simulate the tensile behavior of carbon fiber/carbon nanotube/phenolic resin composites. From the comparison between experimental and static analysis results, it may infer that when strain over 1%, the cracks will work for weaken the tensile strength of the composite.
