- Abstract
- The modified method of synthesis of the polymeric matrixes, consisting in change of structure of precursors (diisocyanate, oligomers, epoxy resin) is developed. The method allows acceleration of the process of preparation of polymeric composite materials (PCM), to realize the process in soft temperature conditions, and also to improve mechanical properties of gradient-modulus PCM on the basis of woven fillers. The strength and relaxation properties of the materials are investigated in dynamic and static modes. It is established that, despite that modules of elasticity for PCM fit within the transitive zone from the glassy to rubbery state, the mechanical behavior of the prepared composites is quasi-elastic, instead of viscoelastic that is characteristic for all polymers in a transitive zone. Optimum structures and conditions of preparation PCM possessing high mechanical properties are defined.
