The adhesive liquid quantity of every square metre of control is brushed to the surface of carbon fiber layer in the range of 450-650g；
（2）After the fiber in intermediate layer is laid on lower carbon fiber layer, vacuum imports microballon formation microbead layer；
（3）Alternately laying fibrous layer and microbead layer, then spread carbon fiber layer；
（4）Hot press is opened, 50-130s is combined in carrying out roll-in under 90-110 DEG C, 0.3-1MPa, takes out and obtains carbon after cooling
Fiber sandwich boards.
