Thermoelastic constants of plastic-impregnated fiberglas in a cross-wound shell

  • Published:
Soviet Applied Mechanics Aims and scope

Conclusions

  1. 1.

    Theoretical calculations on layered Fiberglas material of cross-wound type have shown that there are winding angles and filler contents for which the effective thermal-expansion coefficient and Poisson's ratio become negative.

  2. 2.

    Theoretical calculations have been performed on the magnitudes and ranges of variation of these negative quantities.

  3. 3.

    The theoretical results have been confirmed by experiment for Fiberglas having parameters corresponding to negative values for the thermal-expansion coefficient.
