Performance advantages:
In comparison with the traditional GFRP, 3-D spacer fabric and sandwich construction provide excellent specific stiffness, specific strength, light weight and superior durability. Using such materials on the nose cone and nacelle cover can reduce the product weight by 30-50 percent versus the GFRP materials. And the shrinkage deformation and cracking during the postcure have been solved.

Cost advantages:
Using 3-D spacer fabric and sandwich construction can greatly save raw materials consumption, shorten the production cycle, and improve work efficiency.
