Abstract

The invention discloses a method for preparing a fiber composite material concrete board, which comprises the following steps: laying a first layer of slurry in a mould; laying a first layer of glass fiber grid cloth on the laid first layer of the slurry; laying a second layer of slurry on the laid first layer of the glass grid cloth; laying a second layer of glass fiber grid cloth on the laid second layer of the slurry; laying a third layer of slurry on the laid second layer of the glass fiber grid cloth; vibrating the mould by a vibration device; putting the mould into a steam autoclave; and performing autoclave leaving, demoulding, airing and final treatment to form the concrete board made of the fiber composite material. The invention also discloses a concrete board made of a fiber composite material. The method has the advantages of simple manufacturing process, little capital and equipment input and low cost; and the concrete board made of the fiber composite material has the advantages of low water absorbing rate, high strength, good toughness, high durability, and the like.

Description
