Embodiment Construction

[0020] like figure 1 As shown, the technical parameters of the unmanned boat in this embodiment are that the length of the hull structure is 12.8 meters, the width is 3.2 meters, the height is 3.5 meters, the full water capacity is 13 tons, and the maximum speed is 36 knots; Alkali glass fiber yarn and 300g / m 2 The alkali-free glass fiber plain weave cloth is used as the reinforcing material, and the resin is selected from the medium temperature curing epoxy resin. The resin and glass fiber yarn and plain weave were made into the areal density of 373 g / m 2 of unidirectional fiber prepreg and 461g / m 2 The plain weave prepreg has a resin content of 33% and 35%, respectively.

[0021] 300g / m 2 The alkali-free glass fiber plain weave cloth is compounded with two epoxy resins of the same system, one is made into prepreg by autoclave process, and the other is made by vacuum introduction process to make mechanical properties test panels to test their mechanical properties, such a...

Abstract

The invention discloses a composite material unmanned ship body forming method which comprises the following steps: 1) preparing a mold and equipment, and enabling a ship body structure to comprise nine composite material parts; (2) paving the composite material part; 3) autoclave curing molding; according to the method, the boat body is divided into nine parts by adopting a prepreg paving autoclave curing forming process, the number of the parts is reduced, the parts are cut by utilizing an automatic cutting machine to be paved with the shape-following prepreg, the utilization rate of raw materials is effectively improved, and the utilization rate of the raw materials and the production efficiency are remarkably improved.

Description

technical field [0001] The invention relates to a method for forming a hull of a boat, in particular to a method for forming a hull of a composite material unmanned boat. Background technique [0002] my country's composite boats developed in the 1960s, and the small boats in the current market are basically made of composite materials. The manufacturing process of traditional composite boats is mainly divided into two types, one is manual paste, and the other is formed by vacuum introduction. The hand lay-up process is simple to operate, but the production cycle is long, a large number of air bubbles are likely to exist between the cured layers, the resin content is high, and the mechanical property dispersion coefficient is large. The vacuum introduction process has a short production cycle and high efficiency, but its operation is complicated, and it has certain requirements for the thickness of the layup. It also has a high resin content and a large dispersion coefficie...
