Abstract

When manufacturing large-sized products from polymer composite materials and special processes, the use of conventional metal molds becomes unprofitable because of the large metal, high labor intensity of production (the locksmith and machining) and the energy process.
To solve this problem is more efficient use of large tooling of polymer composite materials.
To improve the cleanliness of the surface shape of the snap-polymer composite materials, the project used the gel coat based on polyurethane or polyurea cold hardening.
As a result, studies were selected in the optimal ratio of polymeric materials in the construction equipment for various applications.
