When 3D fabric is impregnated with a thermoset resin, the fabric absorbs the resin and rises to the preset height. After cured,it became a sandwich panel. This panel made by 3d woven fabric has superior resistance against delamination comparing with traditional honeycomb and foam cored materia,thanks to the integral woven structure,
Main Advantages：
1、Light weight but high strength;
2、Great resistance against delamination;
3、High design-versatility;
4、Space between decklayers can be multi-functional (embedded with sensors,wires or infused with foam);
5、Simple and effective lamination process
6、Thermal and sound insulated.; Fire retardant; Wave transmittable.
The sandwich structure can be used in building of Double Wall Tank & Sump,Railway,Bus,Ship ,Construction,Radome etc.For its great advantages,it will have more and more applicaiton.
