Intelligent carbon fiber composite board

The invention discloses an intelligent carbon fiber composite board. The intelligent carbon fiber composite board mainly comprises a plurality of bundles of CFRP (composite fiber reinforced plastics) filaments, resin and fiber gratings, wherein the CFRP filaments are bi-directional orthogonal CFRP filaments, the fiber gratings are arranged in the middle part of each bundle of CFRP filaments, the fiber gratings are parallel to the CFRP filaments, and the resin fills between each bundle of CFRP filaments and each fiber grating. Each fiber grating is a germanium-silicon fiber bragg grating. The resin is vinyl ester resin. The CFRP filaments are used as a reinforcing material, the resin is used as a reinforcing basal body of the board, the germanium-silicon fiber bragg grating is used as an intelligent monitoring material, and each fiber grating is parallel to the CFRP filaments, so that a resin-enriching area is prevented from forming near the fiber grating, the non-uniform stress area surrounding the sensor can be maximally reduced, the loss of the measurement precision of the fiber grating can be reduced, the performance of the composite board is better than each fiber board in the prior art, and the requirement of a steel structure reinforcing repairing technology can be met.
