The invention discloses a kind of preparation methods of the modified gymnasium suspended absorber of graphene, using staple fiber needle nematophore as precast body skeleton, the technique progress cure process that is impregnated using resin, solidify, carbonize.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, the modified gymnasium suspended absorber of graphene is made.The present invention is using Carbon fibe as skeleton, resin carbon matrix is as reinforcement and by the modified low-density of graphene, porous charcoal/charcoal sound absorber, 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. |
