Researcher Wang Zhen, Ningbo Institute of Materials, Chinese Academy of Sciences, takes you to understand high-temperature polyimide resins and their composites

About high temperature resistant polyimide resin

Advanced resin-based composite materials are prepared through a composite process with organic polymers as the matrix and continuous fibers as reinforcement materials, and are a new type of material that has significantly better performance than the original components

Polyimide resin solution

High-performance polyimide ranks at the top of the high-performance polymer material pyramid by virtue of its comprehensive properties such as light weight, high and low temperature resistance, chemical solvent resistance, low dielectric, flame retardant and excellent mechanical properties, and its wide application prospects have been Get a full understanding, can be called "problem-solving expert", it can be used as special engineering plastics or high-temperature composite material matrix resin coating online coatingol.

Polyimide resin and its composite material application

In the 1970s, NASA developed the PMR-15 polyimide resin.

In the 1990s, NASA and the Air Force Materials Laboratory developed the phenylacetylene-terminated PETI series resins, and the toughness has been greatly improved.

Polyimide resin has formed a material system with 3,4-biphthalic anhydride as the main monomer and phenylacetylene phthalic anhydride as the end-capping agent.
