Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2-3, a reinforced carbon fiber structure includes a carbon fiber reinforced outer layer 1 having a containing cavity therein, wherein the carbon fiber reinforced outer layer 1 is formed by alternately weaving a plurality of first carbon fiber ropes 11 wound in a forward direction and a plurality of second carbon fiber ropes 12 wound in a reverse direction; wherein, at least 1 first carbon fiber rope 11 or at least 1 second carbon fiber rope 12 is formed by splicing a plurality of twisted yarns 101, and the twisted yarns 101 are twisted carbon fiber yarns. The carbon fiber rope (first carbon fiber rope, second carbon fiber rope) formed by splicing a plurality of twisted yarns 101 has good friction resistance and good fracture resistance. And carbon fiber reinforcement skin 1 adopts the mode of first carbon fiber rope 11 and the mutual weaving of second carbon fiber rope 12 to make carbon fiber reinforcement skin 1 can adopt the mode of establishing of cover to fix on the object that the needs of correspondence strengthen the intensity, can remove traditional fixed mode that needs to adopt the carbon fiber viscose to fix the carbon fiber structure on the object that needs strengthen the intensity from.
Fig. 3 shows an application of the twisted yarn 101 as the first carbon fiber rope 11, and the twisted yarn may be applied to the second carbon fiber rope as needed, or the number of the twisted yarns may be increased or decreased as needed.
Preferably, a plurality of twisted yarns 101 are pieced together in a flat plate shape, and a friction groove 102 is formed between adjacent twisted yarns 101. The plate surface of one side of the twisted yarns 101 which are spliced in a flat plate shape is just opposite to the containing cavity, the friction force between an object needing to be reinforced in strength and the reinforced carbon fiber structure is increased through the arrangement of the friction groove 102, and when the reinforced carbon fiber structure is used for filling the object needing to be reinforced in strength (such as a metal concrete bar), fillers of the reinforced carbon fiber structure can be correspondingly filled in the friction groove 102, so that the reinforced carbon fiber structure is not easy to slide on the object needing to be reinforced in strength.
