Effect of the reinforcement structure and type of the matrix on the shear and compressive strength of “Polycarbon“ composites with three-dimensional reinforcement

  • Published:
Mechanics of Composite Materials Aims and scope

Conclusions

  1. 1.

    The process of preparation of the Polycarbon composites based on the pitch matrix facilitates structure formation of the fibers and increases consequently (by 16–50%) the values of Young's modulus. The magnitude of this increase is determined by the processing conditions and reinforcement structure.

  2. 2.

    The type of matrix (pitch, pyrocarbon) has a strong effect on the compressive and shear strength of the composites of this group.

  3. 3.

    The calculated values of the shear modulus of the composites produced on the basis of the pitch matrix with porosity taken into account and Young's modulus values of the composites with the pyrocarbon matrix are in satisfactory agreement with the experimental data.
