Face-to-face Table Lifting Frame A face to face desk stand is a desk design that usually consists of two tables and a middle stand so that two people can sit on either side of the table and work face to face. This design helps promote teamwork and communication, as two people can easily exchange ideas and discuss issues. Face to face table racks also save space because two people can share a table instead of needing two separate tables. In addition, face to face desk racks can also improve the efficiency of the office, as it can reduce the time for communication and coordination, making the team closer and more efficient.

Advanced Carbon/Carbon Thermal Protection Materials— Variable cross-section multi-dimensional woven materials for carbon/carbon screws are suitable for high temperature parts of carbon/carbon composites. Experts at the meeting believed that the performance of carbon/carbon screws, variable-section three-dimensional braided parts, and pin three-dimensional braided preforms developed by Tianjin Polytechnic University exceeded the requirements of the mission book. The product production process is original, advanced and practical. It can replace the high-temperature alloy products for the assembly and fixation of the carbon/carbon composite expansion section, has excellent high-temperature compatibility, and improves the operational reliability of the rocket engine. The successful development of variable cross-section three-dimensional braided carbon/carbon composite screws and pins has filled the gaps in China's carbon/carbon composite three-dimensional shaped integral braided screws and pins, and has reached the international advanced level.
Carbon/carbon composite bolts and pins are advanced, high-performance connectors that are not only in complete conformity with the thermal properties of rocket engine carbon/carbon composite components, but also have outstanding characteristics that do not reduce strength at temperatures of a few thousand degrees Celsius. The successful development of carbon/carbon composite bolts and pins has provided another new material with high strength, light weight, and high temperature resistance for China's aerospace industry.
The advanced carbon/carbon heat-proof material undertaken by Tianjin Polytechnic University, a variable-cross-section multi-dimensional weaving material project for carbon/carbon screws, has been completed after many years of efforts. It has recently passed technical appraisal in Tianjin.
