Metallized polyacrylonitrile fibers — A reinforcing filler for conducting polymeric composite materials

The promise of using metal-containing PAN fibers as a reinforcing filler for PCM was demonstrated. The nickel in the structure of the fiber initiates opening of epoxy rings and reacts with the hydroxyl and epoxy groups in the oligomer. The conductivity of PCM reinforced with metal-containing PAN fibers is a function of the concentration and character of the distribution of the metal in the fiber. It was found that conductivity in PCM is caused by the concentration of free nickel and is similar to the conductivity of metals.Saratov Polytechnical Institute, Tashkent Institute of the Textile and Light Industry, N.

Investigation of the effect of a microwave field on the curing process and properties of epoxy compositions

We present experimental data on the rate and degree of curing of epoxy compositions discretely reinforced with alumina fibers and filled with barium titanate powder on exposure to microwave radiation. We observed the enhancement of the process of epoxy polymer formation, revealed the dominating effect of the filler—polymer interface on the extent of the conversion of a binder and on the properties of heterogeneous compositions cured in a microwave field.
