Considered in the article are issues related to improvement of properties, fabrication and use of polymer matrix composites (PMCs) based on graphite, organic and glass fibers for aerospace industries of Russia and other countries of the CIS. PMCs turned out to be effective in military aircraft and rockets; this has been evidenced by long-term successful experience in operations. The utilization of PMCs in military applications enabled the civil aviation industry to widen utilization of these material systems; for instance the IL-96-300 passenger-carrying airplane incorporates 2.5 t polymer-matrix composites, and the AN-124 transport, 5.5 t. CFRPs (Carbon fiber reinforced plastics) have a feature that enables designers to consider the materials as a promising substitute for metallic alloys in aircraft construction: high allowable tensile and compression stresses not compromised with a high modulus of elasticity; this is extremely important in maneuvrable airplanes. The use of textile forms made of graphite fibers and binary matrices (comprising epoxy and thermoplastic resins) was shown to increase residual strength after impact (by 60 to 80 %), reduce the cracking area, and localize damage. The organoplastics presently used by the aviation industry are based on the polyheteroarylene fibers, SVM, produced in Russia. The SVM fibers have liquid crystal microstructure and are not inferior to Kevlar-49. Organoplastics are derived from epoxy resins and their modifications based on polyfunctional aromatic compounds that form densely connected thermostable meshes during cure. Utilized as the curing agents are various amines: diamine diphenyl sulfon (DADFS), triethyalene amine titanate (TEAT), aniline formaldehyde resins, anhydrides and latent curing agents.
