The invention discloses a kind of KTV preparation methods of Carbon fibe low-density composite acoustic board, using staple fiber needle nematophore as precast body skeleton, are impregnated using resin, the technique that solidifies, carbonize carries out cure process.This method are as follows: one, using Carbon fibe needle nematophore as preform material；Two, the configuration of resin maceration extract；Three, resin impregnates；Four, curing process；Five, charing process；Six, after being machined, KTV Carbon fibe low-density composite acoustic board is made.The present invention is using Carbon fibe as skeleton, low-density, porous charcoal/charcoal acoustic board of the resin carbon matrix as reinforcement, with waterproof, fire prevention, anti-aging, impact resistance is good, with material low energy consumption, environmental protection, discarded rear no pollution to the environment, in use, the advantages that sound absorption effect is good. |
