With the improvement of composite technology manufacturing level, the scale of production and automation progress. Composite materialismore widely used in aerospace, automobile, rail transportation, and other fields. Its application level has become an important symbol of a new generation of equipment advanced nature, composite materials in China accounts for about 30% of the global market share.
HP-RTM process is introduced in recent years, a response to mass production of high performance thermosetting composite parts of new RTM technology, using supporting premolding technology, through the high pressure mixture in airtight vacuum cavity injection of resin immersion and curing, can achieve low cost, short cycle (mass), high quality production.
