Vacuum forming preparation method of helicopter fuselage composite material

Abstract

The invention relates to the technical field of composite material product manufacturing, in particular to a helicopter fuselage composite material vacuum forming preparation method which comprises the following steps: Sp1, preparing a required amount of prepreg, a vacuum bag with a vacuum pipe fitting and an air pump with a control vacuum gauge, Sp2, opening the vacuum bag, placing the prepreg in the vacuum bag, and carrying out vacuum forming on the prepreg; sp3, pasting and laying a drainage fabric on the perforated film layer, sealing a vacuum bag, and communicating a joint of a vacuum pipe fitting with a joint of a control vacuum gauge, Sp4, opening an air pump to vacuumize the vacuum bag, checking the sealing performance of the vacuum bag, and finally, sealing the vacuum bag. The composite material forming preparation process can be carried out under the optimal condition, the composite material vacuum forming preparation process is optimized, the forming effect of the composite material is improved, and the quality of a product prepared from the composite material is guaranteed.

Description

technical field [0001] The invention relates to the technical field of composite material product manufacturing, in particular to a vacuum forming preparation method for a composite material of a helicopter fuselage. Background technique [0002] Helicopter has the characteristics of vertical lifting, hovering, and flying forward or backward at low speed. It is a typical dual-use product for military and civilian use. The disadvantages are low speed, high fuel consumption and short range. It can be widely used in transportation, patrolling , tourism, ambulance and other fields, helicopter design focuses on reducing aircraft weight and improving structural strength, manufacturing complex fuselage and other parts of aircraft, need to use lighter and stronger materials, these materials are composite materials, The molding preparation process of traditional composite materials needs to be optimized, which affects the molding effect of composite materials, and the quality of prod...
