Within the framework of a generalized theory of heat conduction, 
the characteristic equation for glass-reinforced plastics has been 
obtained. Formulas for determination of the velocities of propagation 
of a thermal wave as functions of the slope of the normal to the 
characteristic surface and the angle of orientation of glass-fiber 
threads have been derived. The curves of inverse velocities and radial 
velocities have been constructed.
