Conclusions

  1. 1.

    The initial rupture of LM fibers is unlikely in a hybrid composite containing HM and LM fibers, and defects from HM fibers are accumulated during the initial stage of fracture. The dispersed ruptures grow as a result of stress concentration.

     
  2. 2.

    The possible fracture variants are located between the two extreme cases: alternate rupture of HM and LM fibers −1, 2, 3, 4; rupture of only HM fibers −1, 3, 5, 7.

     
  3. 3.

    An algorithm was developed to search for the most likely variant of fracture and to calculate the strength and damage content of a hybrid composite.

     
  4. 4.

    The amount of damage to HM fibers in a hybrid composite is an order of magnitude greater than the amount of damage to HM fibers in a two-component composite. The hybrid strength effect obtained is negative.
