3D glass fabric is a new materic, which consists of two decklayers bonded together by vertical piles,these piles are woven into the decklayers thus forming an integral sandwich structure. Warp direction shows 8 –shape as a typical st-ructure characteristic.
It represents a strong designability,piles density (both in x and y directions), the height of the piles, the types and th-ickness of Glass fibers all could be designed, based on this, it could be developed to a variety of products with different performances and functions according to customers’ specific requirements.
It overcomes many disadvantages such as delamination and poor impact resistance,which are shown on conven-tional honeycomb core and foam core materials. Furthermore, it has a series of advantages like light-weight, corrosion resistance, high specific strength and modulus ,high impact damage tolerance etc.
