Testing equipment for performance of composite material board

Abstract

The invention provides testing equipment for the performance of a composite material board. The testing equipment comprises a box body, and a humidification mechanism and a supporting mechanism whichare located in the box body, wherein the humidification mechanism comprises a main pipe, branch pipes and spraying pipes, which are connected in sequence; the main pipe, the branch pipes and the spraying pipes are made of stainless steel materials; the main pipe stretches out of the box body and is connected with an air pump, a heating box and an ultrasonic humidifier in sequence; the plurality ofbranch pipes are uniformly distributed at two sides of the main pipe; the spraying pipe is inserted into a free end part of each branch pipe; the spraying pipes and the branch pipes are vertically arranged; the supporting mechanism is located between the two rows of spraying pipes. The testing equipment provided by the invention has the beneficial effects that the humidification mechanism arranged in the equipment can be used for simulating different utilization environments relatively well when the board is applied to different products and detection errors are avoided.

Description

technical field [0001] The invention belongs to the technical field of composite material detection, and in particular relates to a high-temperature and high-humidity test equipment for composite material plates. Background technique [0002] Laminates made of resin-based composite materials have good high-temperature and high-humidity resistance, and are widely used as related materials for aerospace vehicles. Because the use environment of the resin-based composite sheet is extremely harsh, if it is used as a wing surface material, its surface temperature will reach above 100°C, and the ambient humidity around it may reach above 80%. , the moisture-heat expansion deformation of each single layer of the resin-based composite material plate is inconsistent, and the free deformation is limited by the interlayer adhesion. Product performance. Therefore, the detection of the high-temperature and high-humidity resistance performance of the resin-based composite material sheet ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, the detection of the composite material plate is mainly carried out in the electric heating humidification box, but during the test process, the mist entering the box is relatively mild and does not have any impact on the plate, which is greatly different from the use environment of the product. In and out, affecting the test results
