Conclusions

  1. 1.

    The rate of moisture absorption depends on the volume content of organic plastic in hybrid CM, and it increases with increasing content. Hybrid composites with distributed layers of organic plastic have greater moisture absorption than composites with “block” reinforcement with equal content of SVM.

     
  2. 2.

    Thermohumid aging leads to impaired elastic and strength characteristics of organic carbon plastics, mainly on account of the sensitivity of the organic layers to these factors.

     
  3. 3.

    When hybrid CM are exposed to high temperatures and moisture, there are reversible effects (change of the vitrification temperature) as well as irreversible effects (incomplete restoration of mechanical characteristics in uniaxial quasistatic tension and in three-point bending).
