Research of carbon fibre grille reinforced composites in airport pavement snowmelt

摘要

In this paper, the method of melting snow on airport pavement with carbon fibre grille reinforcedcomposites is presented to avoid the adverse effects of snow-melting chemicals. The strengthand resistance of different composites are analysed. The field snow-melting experiments ofpavement in which carbon fibre grilles are embedded in different depths are conducted whenthe snow is heavy. The temperatures along the depth of pavement are analysed at differenttimes. It is shown that, with an input power of 300 W m~(-2), the 2.6 cm thick snow can be meltedwithin 4 hours, which is just for melting snow at this condition. The snow-melting of 5 cmembedded depth of carbon fibre grille is better. The findings indicate that the method of meltingsnow on airport pavement containing the grille made of carbon fibre heating wires and steel baris feasible in the snowy weather condition.
