FIELD: polymer materials.
SUBSTANCE: invention relates to technology of preparing elastic polymeric elements used in curable compositions and can be used in production of composites based on curable binders and reinforced with fibers for use in aircraft industry and in construction. Elastic polymeric element is in solid phase and undergoes phase transfer into liquid phase when dissolved in contact with component of polymeric matrix of curable composition. Dissolution temperature is below temperature of the beginning of gelation and/or composition setting. Element is prepared by formation of melt, extrusion, drawing, processing involving heating upon stretching, and cooling. Element is converted into substrate via stitching, binding, pinching, winding and so forth. Curable composition contains elastic polymeric element or substrate, curable polymeric matrix, and other additives.
EFFECT: improved physico-mechanical characteristics of products.
