Embodiment Construction

[0022] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] Such as figure 1 and figure 2 As shown, this embodiment provides a manufacturing process for a lightweight high-strength carbon fiber composite material rudder. The rudder shape is molded on the rudder mandrel to form a preform 1, and a vacuum-sealed bag is placed inside the preform 1. 2. Put the preform 1 into the outer mold 3 of the rudder, use the vacuum sealing bag 2 and the outer vacuum bag 4 to seal and solidify, and obtain the carbon fiber composite rudder. When preparing the preform 1, mold the prepreg into a rudder shape on the rudder mandrel to form the preform 1; place a vacuum-sealed bag 2 in the preform 1; put the preform 1 into In the rudder outer mold 3, the mold is closed; the preform 1 and the rudder mold are sealed with an external vacuum bag 4 and a vacuum sealing bag 2 on the outside of the mold, and the preform ...

Abstract

The invention provides a manufacturing process of a lightweight high-strength carbon fiber composite material rudder and the obtained rudder. The manufacturing process comprises the following steps: moulding a rudder shape on a rudder core mould to form a pre-forming body; placing a vacuum sealing bag in the pre-forming body; placing the pre-forming body in a rudder outer mould; performing sealing curing formation by using the vacuum sealing bag and the external vacuum bag to obtain carbon fiber composite material rudder. According to the manufacturing process of the lightweight high-strength carbon fiber composite material rudder, the used materials are prepregs, so compared with the common composite material rudder, the lightweight high-strength carbon fiber composite material rudder can precisely control the resin content of the rudder and reduce the porosity of the interior of the rudder. The prepregs consist of a one-way prepreg and a fabric prepreg, wherein the one-way prepreg can provide relatively high strength and rigidity in the main bearing direction; the fabric prepreg can provide longitudinal strength and shear strength and also can provide attractive surface so as to improve the toughness and the handfeel comfortable degree of the rudder.

Description

technical field [0001] The invention relates to a manufacturing process of a lightweight high-strength carbon fiber composite material rudder and the obtained rudder. Background technique [0002] Carbon fiber composite materials have excellent mechanical and chemical properties, such as high specific strength, large specific modulus, good fatigue resistance, and good chemical corrosion resistance. Its specific gravity is less than 1 / 4 of that of steel, its tensile strength is above 1700-3100MPa, its specific strength is more than 15 times that of steel, its tensile modulus of elasticity is 150GPa, and the modulus of steel is 210GPa, which is the highest of steel. 4 times, the rudder made of carbon fiber composite material can reduce the quality of the rudder while meeting the mechanical performance requirements required by the rudder, and meet the goal of low-carbon life advocated now. [0003] At present, carbon fiber composite rudders have been produced, but t...
