Abstract

The invention discloses an I-shaped beam imitating bird scapus fiber arrangement and a preparation method thereof. The I-shaped beam imitating bird scapus fiber arrangement comprises an I-shaped beam body, and a fiber layer with which the I-shaped beam body is covered and which is connected with the I-shaped beam body; the fiber layer is a fiber layer formed by arranging fibers imitating the scapus. According to the invention, the fiber layers distributed by imitating the scapus fibers are connected to the surface of the I-shaped beam, so that the mechanical property anisotropy of the fiber layers at different angles is fully exerted, the bending and torsional deformation resistance of the I-shaped beam is enhanced, the use amount of the I-shaped beam can be reduced, and the weight of the I-shaped beam is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of I-beams, in particular to an I-beam imitating the arrangement of birds' rachis fibers and a preparation method thereof. Background technique [0002] As a widely used load-bearing structure, the I-beam structure is widely used in construction and automobile and ship manufacturing industries. Since the I-beam is mainly used to bear bending and torsional loads, if the load exceeds the I-beam damage during work Tolerance, the I-beam will be permanently deformed or even broken, causing great economic losses and potential safety hazards. With the development of carbon fiber composite materials, the method of reinforcing I-beams with carbon fibers has been widely used. While enhancing the ability of I-beams to resist bending and torsional deformation, it can reduce the amount of I-beams and achieve a substantial reduction in I-beams. Heavy. [0003] In the prior art, the method of carbon fiber reinforced I-be...
