The appropriate parameter and reasonable process of technics is the key for autoclave molding of
composite. The technical simulation of virtual autoclave make for the prediction of curing process, and the improvement
of technical efficiency and reduction of manufacture cost. The paper show a software of autoclave simulation:
COMPRO, and the typical model of curing process analysis: thermochemical model, flow-compaction model and
stress deformation model. At last,the key parameter effect on COMPRO analysis have been shown, and a conclusion
about accuracy of COMPRO analysis can be done through the comparison between the data of spar prototype and
COMPRO simulation.
