Embodiment Construction
[0045] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.
[0046] see figure 1 As shown, embodiments of the present invention include:
[0047] A method for repairing a carbon fiber rod, the specific steps comprising:
[0048] (10) Plan analysis: analyze the repair plan of the bar according to the degree of fracture and damage of the bar, determine the thickness / direction of the layer, and consider how to disperse the stress concentration of the bar when it is stressed.
[0049] (20) Machining: according to the analysis plan, perform surface reduction processing; the connection of the carbon fiber rod to be repaired is processed into a ladder shape including at least three steps, and the step difference...

Abstract
The invention discloses a method for repairing a carbon fiber rod piece. The method specifically comprises the following steps of (10) analyzing the scheme; (20) machining, wherein surface reducing processing is carried out according to an analysis scheme; (30) assembling; (40) cutting parts; (50) paving layers, wherein the cut carbon fiber prepreg is paved according to the structure lamination sequence and the structure lamination direction; (60) solidifying, wherein a repairing area is wrapped by a high-temperature porous isolating film to a circle after the paving is completed, and the wrapped repairing area is put into a repair mold cavity of a repair device for heating and curing; and (70) coating, wherein after the repairing area is repaired and smooth, and the rod piece paint spraying is carried out. According to the method for repairing the carbon fiber rod piece, a method for combining the aluminum tube adhesive and the carbon fiber prepreg in a paving and solidifying mode isadopted, a special repairing device is adopted, so that on one hand, the size precision of the repaired rod piece is not lower than the size precision of the original rod piece, and on the other hand,the bonding between the product layers can be guaranteed; and the strength of the repaired products is not lower than the original strength of the rod pieces.
Description
technical field [0001] The invention relates to the field of carbon fibers, in particular to a method for repairing carbon fiber rods. Background technique [0002] Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1 / 4 of that of steel. The tensile strength of carbon fiber resin composite materials is generally above 3500MPa, which is 7-9 times that of steel. The tensile modulus of elasticity is 230 -430GPa is also higher than steel. Rods or tubes made of carbon fiber have the advantage of being lighter and stronger. [0003] The existing carbon fiber rods can only be discarded when cracks or fractures occur, which is a great waste and greatly increases the cost of using the carbon fiber rods. [0004] Therefore, there is an urgent need for a repair method for carbon fiber rods, which can repair the carbon fiber rods without affecting the mechanical properties of the carbon fiber rods, and can also ensure the accuracy of...
