Embodiment Construction

[0038] Such as figure 1 As shown, the microwave oven used in the present invention for manufacturing three-dimensional spaced conjoined fabric-reinforced resin-based composite materials includes a shell surrounded by cavity walls 1, and the shell has a regular polygonal cross-section. There is a rotating shaft 2 inside the housing, and a turntable 3 is installed on the rotating shaft. Two brackets 4 are arranged symmetrically on the turntable 3. The two brackets 4 support a mold fixing plate 5 for installing a mold. The mold is used to install a three-dimensional interval connection For the body fabric reinforced resin-based composite material preform, the trunnions on both sides of the mold fixing plate 5 extend out of the bracket 4, and the impellers 6 are respectively installed on the extended trunnions, and the positions corresponding to the impellers are on the cavity wall of the shell 1 is provided with a gas nozzle 7 for injecting nitrogen or inert gas.

Abstract

The invention discloses a curing method of a three-dimensional interval conjoined fabric reinforced resin-based composite material and an adopted microwave oven. The curing method comprises the steps: firstly, preparing a preformed body; then impregnating the preformed body with a resin adhesive solution mixed with a wave-absorbing additive; inserting high-thermal-conductivity wave-transparent ceramic strips coated with a release agent into the preformed body; fixing the preformed body on a mold, and mounting on turnover brackets in the microwave oven, introducing nitrogen gas or inert gas into the microwave oven, and maintaining an appropriate pressure; starting the microwave oven, uniformly heating the preformed body in the microwave oven, and under the action of the nitrogen gas or the inert gas ejected from gas nipples, allowing impellers to drive the whole brackets to flip, so as to achieve uniform distribution and curing of the resin in the preformed body; and ultimately preparing a composite material part. The curing method simultaneously adopts five measures of a regular polygonal section, keeping of composite material component rotation and intermittent flipping, magnetron intermittent heating, various heating-up speeds and uniform internally-arranged high-thermal-conductivity elements for cooperative control, so as to ensure uniform curing of the component.

Description

technical field [0001] The invention relates to a processing method of a three-dimensional spaced one-piece fabric reinforced resin composite material component and a matching microwave oven, and the invention is applied to processing a three-dimensional spaced one-piece fabric reinforced resin-based composite material component. Background technique [0002] Lightweight is an important trend in the development of composite materials. Commonly used lightweight composite materials are mostly honeycomb sandwich structures and foam sandwich structures. These sandwich structure composite materials have good light weight and high strength properties and have been widely used. However, the traditional sandwich structure composite materials are glued together to combine the skin and the core material, so the problem of debonding between the surface layer and the core material often occurs during use, especially in the environment of humidity, heat and ultraviolet radiation, which ea...
