Performance of thin ply non crimp fabrics composites

Thin-ply composites are increasingly used in the composite industry due to the various design possibilities and the improved mechanical properties it exhibits when subjected to loading. In this project, two ways of improving the out-of plane properties of C-ply composites were studied. Resin transfe...
