Effect of temperature on the physicomechanical characteristics of carbon-plastics

  • Published:
Strength of Materials Aims and scope

Conclusions

  1. 1.

    The character of the change in the mechanical characteristics of carbon-metal-plastics with heating was shown. It was noted that strength and elastic modulus change more rapidly in compression and bending than in tension.

  2. 2.

    Strain-hardening of carbon-plastic and carbon-metal-plastic was observed in compression within the temperature interval 200–400 °C.

  3. 3.

    It was demonstrated that it is possible to approximate the stress-strain diagram of orthotropic materials with an equation of the form ɛ = σ/E [ 1 + k/n (σ/σp. 1.)n−1], the applicability of which was confirmed by the empirical data.
