Continuous basalt fiber unidirectional fabric is a kind of high performance engineering material, which is coated with sizes compatible with polyester, epoxy, phenolic, and nylon resins, which improve the reinforcing effect of basalt fiber unidirectional fabric. Because of basalt fibre surface activity, the outstanding surface bonding property combined with the resin, furthermore, the basalt fibre belongs to the silicate home, and has the same thermal expansion coefficient, which makes it become the best alternative of the carbon fibre applied in the bridge, construction reinforment and repair. And its CFRP has the outstanding comprehensive property and the cost effectiveness.
