Features and Properties of Solvent-Free PMR-Type Polyimide Resin

The article presents the results of studies of carbon fiber reinforced plastic VS-51/VTkU-2.200. The influence of the thickness of the specimens and the size of working gage on the compressive strength of carbon fiber reinforced plastic specimens was evaluated; tests were done in accordance with different standards. The results of compression strength tests at high temperature (300–320°С) are given: carbon fiber reinforced plastic VS-51/VTkU-2.200 shows high heat resistance and keeps compressive strength at high temperature tests. Carbon fiber reinforced plastic VS-51/VTkU-2.200 is of increasing interest for application in aircraft structural parts requiring high temperature resistance.

The article presents results of studies of experimental carbon plastics based on thermosetting PMRpolyimide binder. Сarbon fiber reinforced plastics (CFRPs) are made from prepregs prepared by melt and mortar technologies, so the rheological properties of the polyimide binder were investigated. The heat resistance of carbon plastics was researched and its elastic-strength characteristics were determined at temperatures up to 320°С. The fundamental possibility of manufacturing carbon fiber from prepregs based on polyimide binder, obtained both by melt and mortar technologies, is shown. CFRPs made from two types of prepregs have a high glass transition temperature: 364°C (melt) and 367°C (solution), with this temperature remaining at the 97% level after boiling, and also at approximately the same (86–97%) level of conservation of elastic strength properties at temperature 300°С.
