Double-layer composite disposable wipes The advantages of fiber composite materials for material selection

Disposable rags are more and more popular in daily life. From traditional rags to disposable rags, people have changed their new ideas about kitchen cleaning. Not only should they be able to understand the characteristics of each material, but also pay attention to it. Are different materials the same as you need, and now fiber composite materials have different advantages, let's take a look.


We should conduct in-depth research on new low-temperature insulation technology (including insulation structure material technology, etc. and apply it to the heat shield support of radiant refrigerators, etc., and develop it with the same volume and weight or little increase in the case of traditional radiant refrigerators. (B) a highly efficient radiation refrigerator with a greatly improved refrigeration index. These issues include new materials and process structure mechanical properties and reliability pollution control and heat pipe coupling ground assembly and testing and other technologies.

At present, the pollution control technology during the ground storage and transportation of the radiant refrigerator and on-orbit work needs to be improved and developed to further improve its working life. In addition, the matching coupling technology of the radiant cooler and the multi-band multi-channel large-area array infrared detector. The heat pipe technology as a high-efficiency thermo-mechanical coupling technology involved in other refrigeration methods of pre-cooling also needs to be further researched and developed , In order to broaden the application field of space radiation refrigeration technology.


Strengthening of the whole process of the fiber reinforced composite bending member due to the high strength, light weight, corrosion resistance, fatigue resistance and ease of construction of fiber materials, the use of fiber reinforced composite materials (FRP) for structural reinforcement has attracted increasing attention. . The experimental research results of fiber-reinforced beams show that the load-bearing capacity and stiffness of the beams strengthened by externally-attached fibers are significantly improved, but the ductility of the cross-section is greatly reduced. In terms of cantilever plate reinforcement, the feasibility and anchoring method of fiber reinforced cantilever plate were discussed, and the bearing capacity of the reinforced cantilever plate with additional anchoring on the plate was studied.
