Safe composite manufacturing method and device for wire-containing multifunctional material

Abstract

The invention discloses a safe composite manufacturing method and device for a wire-containing multifunctional material. The method comprises the following steps that a heat insulation material is extruded by a high-precision contour spray head of a manufacturing head to be cured at a low temperature to form a contour belt; accurately wire conveying is conducted through a feeding roller; a heat insulation material is extruded by the high-precision contour spray head to the wire laying starting position, and cured at a low temperature so as to fix a wire at a curing point; starting from the curing point, while the feeding roller is rotated to lay the wire, an energetic material is extruded by using a high-efficiency filling spray head of the manufacturing head, and the energetic material iscured at the low temperature along with the laying of the energetic material; a heat insulation material is extruded to the wire laying tail end position by using the high-precision contour spray head, and cured at a low temperature so as to fix the wire at a curing point; the wire is accurately cut off; and the steps are repeated until part machining is completed. In addition, the invention further discloses the safe composite manufacturing device for the wire-containing multifunctional material.

Description

technical field [0001] The invention relates to a method and device for manufacturing multifunctional materials, and more particularly to a method and device for safely composite manufacturing multifunctional materials containing silk. Background technique [0002] Multifunctional materials with embedded electrodes are usually made of electrode materials, energetic materials, adhesive materials, etc., and are the basis for manufacturing important equipment in aerospace, national defense and military industries, such as engines and warheads of rocket engines and missiles. and other manufacturing fields. The manufacturing technology of multifunctional materials with embedded electrodes is the key, which has high requirements on safety, efficiency, and manufacturing precision. At present, the manufacture of multifunctional materials with embedded electrodes is usually based on handwork, involving a large number of manual operations, and there are serious shortcomings in terms ...

AI Technical Summary

Problems solved by technology

However, first of all, this type of technology usually uses two kinds of materials such as carbon fiber or yarn and thermoplastic matrix as raw materials to manufacture structural load-bearing components, and does not involve more than two kinds of embedded electrode materials. The manufacture of multifunctional materials such as materials; secondly, this type of technology usually uses soft non-metallic fibers as raw materials, which cannot accurately control the shape and position of the wire during processing, and the dimensional accuracy of the processed components is poor (usually 1mm level); in addition, this type of technology requires heating, melting and curing of the thermoplastic matrix during the manufacturing process, and needs to be heated to a high temperature above 150°C, which poses a great safety risk for the manufacture of energetic materials

Therefore, the above-mentioned technologies still cannot realize the safe and efficient automatic manufacturing of multifunctional materials containing filaments.
