Abstract: Tensile performances of the laminated plates made from T700 Carbon Fiber/Glass Fiber and T700 Carbon Fiber/Basalt Fiber with different ratios were studied. The study found that tensile performance of hybrid fiber composite laminated plates was proportional to the content of the carbon fiber. High fracture displacement of fiber could improve the elongation at break of hybrid fiber composite materials. The theoretical value from mixed composite modulus formula was close to the actual measure value, and the reliability of new hybrid fiber formula was verified. The toughness of pure carbon fiber composite was improved by adding glass fiber or basalt fiber, and the costs would be saved at the same time.
