| Abstract: | The design theory of intraply hybrid composite laminate with in-plane 2D zero thermal expansion coefficient was studied in order to meet the thermal stability of FRP in space alternating temperature field.The influence of fiber content,hybrid ratio and orientation angle of fibers on thermal expansion coefficient of laminate was analyzed with the use of micromechanical analysis and classical lamination theory.A design theory about the in-plane 2D thermal expansion of hybrid composites was proposed.According to the theoretical analysis and experimental results,the in-plane 2D zero thermal expansion can be achieved through proper design of fiber content,hybrid ratio and layering of laminate. |

| Keywords: | thermal expansion coefficient hybrid ratio in-plane 2D zero expansion |
