Project Background:

 

Fiber reinforced polymer (FRP) materials, with light-weight, high strength, corrosion resistance, and superior uni-directional mechanical properties along the fiber direction can effectively solve the problem of corrosion in civil engineering. However, the disadvantage of low modulus (only 70-75GPa) of the glass fiber reinforced polymers (GFRPs) produced from conventional glass fibers is prominent, and their modulus will further decrease with increasing temperature. How to solve this problem has become particularly 


Aims & Goals:
1. To obtain the structural origin of the Elinvar effect in oxide glasses, and realize the controllable preparation of high-modulus oxide glasses with Elinvar effect and glass fibers;
2. To dope SiO2, TiO2 or graphene into epoxy resin to achieve its toughening modification;
3. To prepare the high-modulus GFRP with Elinvar effect by compounding the produced glass fibers and modified epoxy resin;
4. To realize the integrated design of members and joints in truss structures of GFRP through optimized the connection efficiency of the components.
