Embodiment Construction

[0015] The present invention will be further described below in conjunction with embodiment:

[0016] Such as figure 1 As shown, the carbon fiber composite handle for a lawn mower includes a thin-walled metal layer 1, an adhesive layer 2, a carbon fiber cloth layer 3, and a film layer 4 arranged in sequence from the inside to the outside. Among them, the thin-walled metal layer 1 is a titanium alloy sheet of 0.1-0.3mm, and the adhesive layer 2 is a modified epoxy resin of the type J133. J133 has a large cohesive force and a high bonding strength, which can ensure that the adhesive structure can withstand A certain degree of shock, vibration and long-term dimensional stability, the film layer 4 is a PET film with a thickness of 12-20 μm.

Abstract

The invention relates to a carbon fiber composite grip for mowers, belonging to the technical field of carbon fiber composite materials. The carbon fiber composite grip for mowers comprises a thin-wall metal layer, an adhesive layer, a carbon fiber cloth layer and a film layer which are sequentially arranged from inside to outside, wherein the thin-wall metal layer is a titanium alloy sheet; the adhesive layer is a J133 modified epoxy resin; and the film layer is a PET (polyethylene terephthalate) film with the thickness of 12-20 mu m. The carbon fiber composite grip is formed by simultaneously rolling the carbon fiber cloth and titanium alloy sheet, thereby saving the production cost, and greatly enhancing the strength of the grip. When the people need drilling the grip so as to make connection with the mower head, the strength of the drilling position is supplied by the isotropic titanium alloy sheet, thereby avoiding damaging the overall mechanical strength. The carbon fiber composite grip for mowers has wide market popularization prospects.

Description

technical field [0001] The invention relates to a carbon fiber composite handle for a lawnmower, belonging to the technical field of carbon fiber composite materials. Background technique [0002] Carbon fiber is an inorganic polymer with a carbon content of more than 90% made from organic matrix fibers (polyacrylonitrile, viscose or pitch, etc.) at a high temperature of 1000°C-3000°C and an inert gas environment, after pyrolysis and carbonization. fiber. The mechanical properties of carbon fiber are excellent, the specific gravity is less than 1 / 4 of steel, and the tensile strength of its composite material is 7 to 9 times that of steel, and the Young's modulus is 3 times that of traditional glass fiber. -49) twice. In addition, carbon fiber also has excellent properties such as chemical corrosion resistance, electrical conductivity, small expansion coefficient, shock absorption, and low density. It is an indispensable strategic new material for national economy and natio...
