Manufacturing method of composite material product coil stock core mold

The invention relates to a manufacturing method of a composite material product roll material core mold, which is formed by pouring and room temperature curing a finished composite material product as a mold by using a double-component liquid silicone rubber cured material capable of being cured at room temperature. The double-component liquid silicone rubber condensate is addition polymerization type room temperature curing double-component silicone rubber or polycondensation type room temperature curing double-component silicone rubber, the room temperature initial preparation viscosity is 10-1000000 cps, the viscosity doubling time is 10-120 min or above, and the hardness of the condensate is 20-70 A degrees, so that the double-component liquid silicone rubber condensate can have good flowability and filling performance in the room temperature state, and the double-component liquid silicone rubber condensate can be used for preparing the high-performance silicone rubber. And the method has a relatively goo
