Advanced composite material experiment furnace

Abstract

The invention relates to the field of material industry, in particular to an advanced composite material experiment furnace. The furnace comprises an experiment furnace double-layer outer frame and amechanical pump, wherein heating cavities are formed inside the experiment furnace double-layer outer frame, and the heating cavities are composed of upper cavity heating belts and lower cavity heating belts; upper cavity heat preservation layers are arranged outside the upper cavity heating belts, and upper cavity crucibles are arranged inside the upper cavity heat preservation layers; lower cavity heat preservation materials are arranged outside the lower cavity heating belts, and lower cavity crucibles are arranged inside the lower cavity heating belts; and discharging pipelines are arranged at the bottoms of the upper cavity crucibles. According to the advanced composite material experiment furnace, the cavity at the upper portion cannot be oxidized by air during high-temperature smelting through a vacuum unit, and when a base material at the upper portion melts and flows into a reinforcement material, the composited material cannot generate bubbles and is more compact due to the action of high vacuum.

Description

technical field [0001] The invention relates to the field of material industry, in particular to a furnace for testing advanced composite materials. Background technique [0002] With the continuous development of science and technology, a large number of new structural materials have emerged. The most primitive structural materials, such as rice straw and wheat straw reinforced clay, and the reinforced concrete that has been used until now are all made of two materials. Now there are glass fiber reinforced plastics, carbon fiber, graphite fiber, silicon carbide fiber, etc., which all belong to the category of compatible materials. Corrosion and special functional materials have been regarded as national strategic new industries. The composite material test furnace is mainly to provide a kind of experimental equipment for liquid phase forming of composite materials. It mainly melts the matrix and fills it into the reinforcing material. The previous method is The matrix mate...

AI Technical Summary

Problems solved by technology

[0004] 1. The whole smelting process is carried out in an aerobic state. Part of the melted matrix will cause oxidation, and the bonding force is often not strong enough after being poured into the reinforcement material.

[0005] 2. Since the whole process is carried out under atmospheric pressure, the combined materials often have bubbles, and the overall structure of the formed composite material is not dense, and the strength and quality cannot meet the expected requirements
