The advantages of fiberglass stitchbonded fabrics are as follows:
1/ It can increase the ultimate tensile strength of FRP laminated products, the delamination resistance under tension and the bending strength;
2/ reduce the weight of FRP products;
3/ The surface is smooth to make the surface of the FRP smooth;
4/ Simplify the hand lay-up operation and increase labor productivity. This reinforcing material can replace continuous strand mat in pultrusion FRP and RTM, and can also replace gingham in the production of centrifugal glass tubing.
