b) mixing an equivalent excess of the
polyisocyanate with the excess based on the
polyol, with the first mixture, to form a
second mixture; and
c) forming and reacting the second mixture
under a pressure of at least 1 Kg/cm2 to form
the composite.
21. The process of claim 20 wherein the forming
and reaction are carried out in a mold at a pressure
of from 1 Kg/cm2 to 100 Kg/cm2.
22. The process of claim 21 wherein the mold is
a pressure tight mold.
25. The process of claim 22 wherein the forming
and reacting are carried out at a temperature of from
10ºC to 30ºC.
28. The process of claim 25 wherein the pressure
is from 50 Kg/cm2 to 100 Kg/cm2.
36. A product of the process of claim 20.
37. A product of the process of claim 22.
38. A product of the process of claim 25.
39. The process of claim 20 wherein an
equivalent ratio of NCO groups to OH groups in the
second mixture, before reaction, is not greater than
5:1.
