Research On Capability Of Carbon Fiber-glass Fiber Grating And It’s Appliance On The Pavement’s Ice And Snow Melting

Based on the research of electric melting snow method and studied the high cost performance of carbon fiber-glass fiber grating conductive body. First, studied carbon fiber-glass fiber grating different weave scheme in the grill have what influence on the mechanics properties; Again according to the power requirements on the road melting snow ice, carbon fiber-glass fiber grating in the wiring of electrical conductor arrangement and the ice melting snow pavement structure scheme; Finally, going a step further research of carbon fiber-glass fiber grating pavement on the site of snow melting ice test and rutting test. Get the following conclusion:(1) According to unidirectional fiber bundle tensile test, the breakage strength of carbon fiber-glass fiber grating fiber bundles of tensile not only the different fiber bundle fineness have influence it, but also the different effects of coating material. Determine the grille to the fiber materials for carbon fiber and glass fiber’s mixture, fine degrees for1600Tex (CF)+2200Tex (GF); The zonal fiber materials for pure glass fiber, fine degrees for4400Tex. Case rib tests and numerical test results show that the carbon fiber glass fiber grating’s tensile strength meet the national standard GB/T21825-2008requirements.(2) According to the carbon fiber-glass fiber grating used in road melting snow ice’s and the power requirements, and deduced the electric grid of the carbon fiber and it’s line resistance, grille nets holes, width and in the areas of unit fever the number of carbon fiber root quantitative relationship, this can determine the power requirements of different carbon fiber wiring schemes. And grille lays on the asphalt concrete road surface5cm, can guarantee the middle surface temperature in the heating process can quickly rise to0℃and it’s above. At the same time, in the process of heating the electric resistance basic remain unchanged.(3) Making the carbon fiber-glass fiber grating of melting snow ice road surface model, using the road surface model to make a outdoor snowmelt test. Visible, conductive body after electrify can achieve the purpose of melting snow. Carbon fiber-glass fiber grating to lay on the asphalt concrete pavement can improve the in the dynamic stability, strengthen the stability of the pavement. In the rutting circumstances, the carbon fiber-glass fiber grating conductive body resistance in basically no change, which can provide for the process of heating temperature melting snow process of the more stable power.This study for the path of snow melting ice provides a safe and reliable, green, simple construction of the new method, it’s have guiding significance on the carbon fiber-glass fiber grating research and development and engineering application.
