Polydicyclopentadiene building template material and its preparation method

The invention discloses a polydicyclopentadiene building template material. The polydicyclopentadiene building template material is obtained through blending polymerization of 80-99.99wt% of dicyclopentadiene and 0.01-20wt% of a glass fiber. The polydicyclopentadiene building template material selects the glass fiber as a reinforcement material to undergo blending polymerization with the dicyclopentadiene to synthesize the composite material, so the impact strength and the tensile strength of the polydicyclopentadiene material can be substantially improved only through adding a small amount of the glass fiber. The impact strength of the composite material is improved to 180-350J/m from original 100J/m of the single polydicyclopentadiene material, and the tensile strength of the composite material is improved to 30-35MPa from original 25MPa of the single polydicyclopentadiene material. The polydicyclopentadiene building template material enables building templates to be 1/6-1/7 lighter than templates prepared
