Embodiment 1

[0039] The present invention is a method for integrated solidification and molding of the fuselage and vertical tail of a micro UAV. The specific steps of the method are as follows: select 1K carbon fiber reinforced bidirectional weaving prepreg adhesive tape, use epoxy resin as the matrix, and integrate multi-axial positioning The molding process method is used to make the thin-shell streamlined fuselage and the overall structure of the vertical tail.

[0040] Step 1: The carbon fiber bidirectional cloth impregnated with epoxy resin glue is cut to have a length above the circumference of one outer surface of the punch;

[0041] Step 2: Cut the length of carbon fiber bidirectional woven cloth that is more than one outer surface of the punch to cover the upper layer of the punch carcass, and use two pieces of fiber reinforced pre-impregnated adhesive tape as the laminate material for the fuselage and vertical tail , put it into the mold, and fix each molded block with bolts;

Embodiment 2

[0044] The present invention is a kind of integrated curing molding method of the fuselage and vertical tail of a micro UAV. The specific steps of the method are as follows:

[0045] Aramid fiber bidirectional weaving and phenolic resin are used as the matrix, and the multi-axial positioning integrated molding process is adopted to make the thin-shell streamlined fuselage and vertical tail overall structure.

[0046] Step 1: The carbon fiber bidirectional cloth impregnated with epoxy resin glue is cut to have a length above the circumference of one outer surface of the punch;

[0047] Step 2: Cut the length of the outer surface of the punch to a length greater than the circumference of one outer surface of the punch. Carbon fiber two-way woven cloth is wrapped on the upper layer of the punch body, and two pieces of fiber-reinforced pre-impregnated tape are used as the laminate material for the fuselage and vertical tail. , put it into the mold, and fix each molded block with b...

Abstract

The invention relates to an integrative solidifying and molding mold of a minitype unmanned aerial vehicle body and a vertical fin; the mold is composed of a convex mold, a concave mold and a bolt andnut; the convex mold is a steel mod with a convex shape, which is consistent with the stream line form of the vehicle body; the concave mold which is a steel mold is formed by a left side mold pressing block and a right side mold pressing block which are connected by the bolt and nut, and the inner shape of the concave mold is consistent with the stream line form of the vehicle body. An integrative solidifying and molding method of a minitype unmanned aerial vehicle body and a vertical fin comprises three steps: 1. material preparation, the selected fiber reinforcement pre-impregnated fabricis cut into needed size; 2. the prepared material by the step one is paved on a matrix of the convex mold with one layer, and then the material is wrapped on the pre-impregnated fabric with another layer continuously, after sequential pavement is carried out, the designed paving layers are achieved, and then the convex mold is placed in the convex mold, and the bolt and nut is used for fixing alllocating pieces of axial mold assembly of the whole mold; 3. the whole mold is placed in a solidifying box and is solidified by temperature rising between 140-170 DEG C, and the mold is taken out after the temperature is naturally decreased to 60 DEG C and then is demoulded. The method realizes integrative formation of a complex structural piece.

Description

1. Technical field: [0001] The invention relates to a thin-shell streamlined fuselage and vertical tail integral solidification molding technology for a micro-UAV, in particular to a micro-UAV fuselage and vertical tail integrated solidification molding method and its curing mold, belonging to the field of UAV manufacturing technology . It adopts the process method of continuous fiber reinforcement layering and integrated positioning mold, and focuses on solving the difficulty of integrated forming process of complex composite structural parts. 2. Background technology: [0002] Since the 1940s, polymer-based composite materials and their molding methods have been studied. With the rapid development and improvement of the polymer composite industry, many new methods have emerged. However, the weight requirements of micro UAVs are very strict. If the conventional connection method is used between the fuselage and the wings and other components, on the one hand, it is easy to...
