Abstract: his paper describes a new technology of winding grain with compositematerials.In this technology,the grain,fore and aft domes, liner and insulation are assembled into a multipart mandrel which is wound with composite material into a generator.The remarkble advantage of this technology is its reliable quality,but the disadvantages are the dangerous winding process.Threrfore,before the winding process,thegrain performance must be well known and necessary individual test should be carriedout as well as the《Technical Safety Regulations on the Fire Work Preduction 》must bestrictly implemented so as to ensure safety in production.
