  • Method for making a thermally protective coating for a propulsive unit structure
    Patent number: 7368025
    Abstract: A method of making a thermally-protective coating on a thruster structure, the method consisting in: continuously measuring out and mixing (14) at least one polyurethane and a mixture of polymerization agents in which specific fillers have previously been dispersed; coating a rotating cylindrical support surface (2) by continuously casting a strip (18) of touching turns of the resulting mixture; and pre-polymerizing the resulting coating at ambient pressure so that said polyurethane becomes polymerized sufficiently to be capable of being stressed mechanically.
    Type: Grant

  • Reinforced plastic material and a process for the production thereof
    Patent number: 4123476
    Abstract: A reinforced composite plastic material has a matrix of thermoplastic material in which is dispersed at least 5% by weight of a polyethylene having a very high molecular weight. The reinforcing polymer is in the form of fine particles which, in large proportion, are drawn out in the form of elongated fibrils which impart considerable strength to the resulting composite plastic material.
