Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the glass fiber used in the existing fiber metal laminates has low tensile strength, is easy to wear, and the fiber is brittle, and the processing and weaving entanglement is weak during use, and the skin-friendly property to the human body is poor; The carbon fiber has low shear strength, is easy to break, and has low elongation after breaking. Although it can be mass-produced, the market price remains high all the year round; using a hot press for the hot-pressing preparation process of the laminate, the hot-pressing time is long and the preparation efficiency is high. Low, unable to perform high-volume and high-efficiency production tasks, the overall preparation cost of laminates will be high

Abstract

The invention relates to an ultrahigh molecular weight polyethylene (UHMWPE) fiber reinforced fiber metal laminate. The UHMWPE fiber reinforced fiber metal laminate is formed by alternately superposing metal thin plates and UHMWPE fiber reinforced prepregs; and the metal thin plates and the UHMWPE fiber reinforced prepreg sheet materials are formed through adhesion of adhesive and rolling. The UHMWPE fiber reinforced fiber metal laminate is high in tensile strength, not liable to wear, high in fiber tenacity, high in processing, weaving and winding properties and high in skin friendliness; the fiber is high in shear strength and not liable to break, and the cost of the fiber is greatly reduced as compared with that of carbon fiber; preparation equipment is high in work efficiency and can be competent for a mass and high-efficiency production task, and the total preparation cost of the laminate is low; manufacturing devices are clever in design, and a metal thin plate guide device, a prepreg guide device and an adhesive spray-coating device cooperate with each other to complete high-efficiency and high-quality production work.

Description

technical field [0001] The invention belongs to the technical field of composite material manufacturing, and in particular relates to a fiber metal laminate reinforced by ultra-high molecular weight polyethylene fibers and a preparation method thereof. Background technique [0002] Fiber metal laminate is a kind of interlayer hybrid composite material formed under certain temperature and pressure after alternate lamination of metal sheets and fiber-reinforced prepregs. Fiber metal laminates have been successfully applied in the aerospace field due to their high specific strength and specific stiffness, excellent fatigue crack growth resistance and impact resistance. [0003] Chinese Invention Patent Publication No. CN 103029376 A, published on April 10, 2013, the patent document titled "A metal-fiber composite laminate and its manufacturing method" discloses a glass fiber or carbon fiber reinforced, using Fiber metal laminates formed by heat press. The glass fiber used in ...
