Preparation method of carbon fiber reinforced resin matrix composite plate

Abstract

The invention provides a preparation method of a carbon fiber reinforced resin matrix composite material. According to a carbon fiber reinforced resin matrix composite material plate processed by thepreparation method, in the machining process, the self-adaptive mold pressing action is innovatively adopted, and during the mold pressing of a carbon fiber reinforced resin-based composite material blank, a pressing head can perform corresponding actions in a manner of self-adapting to the surface of the blank; in the whole mold pressing process, the pressing head can be dynamically adjusted to adapt to the surface of a continuously-changed blank, stress in the carbon fiber cloth layer obtained after the action is absorbed, resin between the layers is fully and evenly impregnated, and therefore, the mechanical property of the carbon fiber reinforced resin matrix composite plate obtained after model forming is remarkably improved.

Description

technical field [0001] The invention relates to the field of composite material plate preparation, in particular to a method for preparing a carbon fiber reinforced resin matrix composite material plate. Background technique [0002] As a new type of composite material, carbon fiber reinforced resin matrix composites have the advantages of low specific gravity, high strength, high tensile elastic modulus, small thermal expansion coefficient, good vibration resistance and vibration absorption performance, etc., so it has been a research hotspot. The preparation method of carbon fiber reinforced resin matrix composites has a crucial influence on the performance of carbon fiber reinforced resin matrix composites. In the prior art, compression molding is generally used for the preparation of carbon fiber reinforced resin matrix composites. However, in the prior art The focus of the preparation method is temperature and airtight environment, and there is no special requirement fo...
