Abstract

The thermal deformation of a heat-shielding coating of polymer composite material with a phenol-formaldehyde matrix under conditions simulating the temperature-time interval of descent of a spacecraft from orbit is considered. It is shown that in the plane of reinforcing of the composite the maximum thermal deformations occur in a direction 45° to the base of the fabric of the filler and with an increase in heating rate there is a significant reduction in the amplitude of its dilatometric values. The residual relative thermal deformation of the heat-shielding material tested to a program of descent from a trajectory may reach 2% and more.
