Abstract

The invention relates to a modular test box for space material experiment samples, which includes a box body, a box cover, an installation tray and several sample modules, the box cover is hinged on the box body, and sample trays are respectively installed on the inner sides of the box body and the box cover; The module includes an installation support structure and sample materials, the installation support structure is detachably connected to the installation tray, the sample material is limitedly supported on the installation support structure, and its exposed surface is arranged toward the side away from the installation tray. The test chamber of the present invention can realize on-orbit experimental testing of materials in extremely harsh environments such as space atomic oxygen denudation, space high and low temperature alternation, space high-energy particle radiation, microgravity, ultra-high vacuum, space debris / micrometeoroid impact, etc. . At the same time, it is beneficial to ground laboratory installation, water removal, gas removal, dust removal treatment, on-orbit disassembly and replacement, and disassembly after returning to the ground; it meets the aerospace characteristics of compact structure, small size, low weight, and reliable mechanical properties during the rocket launch up phase.

Description

technical field [0001] The present invention relates to the technical field related to aerospace material exposure experiments, specifically to the interdisciplinary research fields of space material science and space physics science, and specifically to a modular test box for space material experiment samples. Background technique [0002] After investigation, it was found that famous foreign aerospace agencies such as NASA, Russian Aerospace Agency (RSA), European Space Agency (ESA), Japan Aeronautics and Space Agency (JAXA), etc., conduct material exposure tests based on the International Space Station (ISS). As well as the development of the sample experiment module, according to different test purposes and requirements, a variety of material on-orbit test devices are designed for material systems such as metallic materials, inorganic non-metallic materials, polymer materials, and composite materials. In China, no relevant work has been retrieved on the development of sp...
