Embodiment Construction

[0022] The inventive method comprises the following steps:

[0023] a) Put the main body resin of the fireproof coating in the glue tank of the film coating equipment, and coat it on the release paper to form a continuous fireproof film;

[0024] b) Lay materials on the mold, the laying order is: aluminum alloy plate, fireproof film, glass fiber prepreg layer, aluminum alloy plate, glass fiber prepreg layer, fireproof film, aluminum alloy plate to form parts preformed body;

[0025] c) Give the green body pressure and temperature to solidify the green body on the mold.

[0026] The thickness of the aluminum alloy plate is 0.2-0.5mm, and the glass fiber prepreg layer is composed of multiple layers of glass fiber prepreg. The nominal thickness of the glass fiber prepreg single layer is 0.125mm-0.200mm. Cured at 115°C to 125°C, the glass fiber volume fraction is 60% to 70%.

[0027] The thickness of the fireproof adhesive film is 0.2mm~0.3mm, and it is laid on the inner side o...

Abstract

The invention relates to a preparing method for fire-resistant glass fiber - aluminum alloy hybrid laminates. The hybrid laminates consist of fireproof film, glass fiber prepreg layer and aluminum alloy plate. The preparing comprises the following steps: coating a fireproof film, paving and curing molding. The fire retardant coating native resin is coated into a continuous fireproof film, and the fireproof film is led to the area between the glass fiber prepreg and the surface aluminum alloy plate. The thickness of the fire protection layer is 0.2 mm - 0.3 mm, with characteristics of fire resistance, which can effectively isolate the fire and heat shocks after fire. It can be used for aviation aircraft cabin cabinets, car fuel tank cover and other parts prone to fire.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a preparation method of a fireproof glass fiber-aluminum alloy hybrid laminate. Background technique [0002] Composite materials are more and more widely used in aerospace and civil vehicles. A large number of metal materials are gradually being replaced by composite materials. However, single resin-based composite materials are also hindered by anisotropy and poor impact resistance. its application in certain fields. Combining the advantages of composite materials and metal laminated structures, it has the characteristics of fatigue resistance, low density, high specific strength of resin-based composite materials and good toughness of metals. This material can widely replace traditional metal materials. [0003] At the same time, the safety performance of materials is the focus of engineers' consideration during the application process. Fire is an important factor c...
