| titleOfInvention | Preparation method of missile launching frangible cover |
| abstract | The invention belongs to the field of manufacturing of fragile covers and discloses a manufacturing method of a missile launching fragile cover. Weighing the following materials in parts by weight: 100 parts of epoxy resin, 50-150 parts of curing agent, 0.05-6 parts of accelerator, 0.2-5 parts of coupling agent and 10-40 parts of hollow glass microsphere, and then uniformly mixing all the materials; laying a layer of fiber cloth on the inner surface of the fragile cover die, uniformly coating a layer of coupling agent on the surface of the fiber cloth, and filling the prepared slurry into the fragile cover die; sealing the mold, and then pressing and molding; curing according to a curing process of firstly preserving heat for 1-3 h at 80-90 ℃, then preserving heat for 2-4 h at 100-120 ℃ and finally preserving heat for 1-3 h at 140-160 ℃; and demolding and taking out to obtain the missile launching frangible cover. The invention overcomes the defects of large mass, long opening time, high cost and the like of the traditional fragile cover, and the fragile cover prepared by the invention has the characteristics of simple and convenient operation, high reliability, light weight, high strength, wear resistance, high temperature resistance, oxidation resistance and the like. |
