To being impregnated with completely, then sample is exposed in wet environment and carries out precuring.
Described wet environment, for the water vapor atmosphere of relative humidity more than 95%.
The time of described precuring is 24h.
The temperature of described precuring and maintenance is 20-25 DEG C.
Described it is immersed in the water maintenance to the most fully hardened.
Compared with prior art, the invention has the beneficial effects as follows: it is multiple that the present invention has gained carbon-fiber cement
Condensation material thermoelectricity capability is stable, good mechanical performance, molding and the simple feature of maintaining process.The present invention
The PAN base chopped carbon fiber tensile strength used is high, electrical conductivity is high, thermal conductivity is low and stable chemical performance,
It is possible not only to increase substantially the mechanics of Carbon Fiber Cement-based Composites and thermoelectricity capability, and avoids
The problem that the composite material strength using expanded graphite to bring reduces.The present invention is dry-pressing formed prepares carbon fiber
The method of cement-base composite material, owing to typed pressure is bigger, it is to avoid when pressure is less, the porosity is high
Problem.The maintaining process of the present invention, is placed on the sample after dry-pressing formed on the water saturated sponge sheet of suction,
Utilize capillarity to make it absorb water to completely to be impregnated with, then sample is exposed in wet environment and carries out precuring
Protect, the problem that precuring insufficient generation micro-crack can be prevented effectively from, make to prepare mechanics and thermoelectricity capability is excellent
Good Carbon Fiber Cement-based Composites is possibly realized.
