Aiming to resolve the technical matters such as uneven pressure on products

pits on the panel

improvement of the inner quality

based on the analysis of co-curing method

the T shape stiffened panels were researched in this paper. The match condition

process parameters and orientation of the stringer are analyzed and optimized. The fabrication process of T shape stiffened panels and technical details are improved. The results show that the test product quality is excellent

the product inner is compact

the surface is smooth and the stringer axis is accurate.
