ABSTRACT:
A method of forming a synthetic article by open forming techniques by providing a fluid composition containing a predominant quantity of synthetic resin and having a capability for delayed, substantial gas evolution. To produce reinforced articles, the composition is applied to the reinforcement at a temperature below a predetermined gas evolution temperature and is subjected to fluid spreading conditions to thoroughly wet the elements of reinforcement. Subsequently, the fluid composition reaches the predetermined temperature, the resultant gas evolution effectively expands the composition while it remains in thorough wetting contact with the reinforcement elements, and the resin then solidifies and cures to produce an intimately reinforced, expanded article. In important embodiments the preponderant gas evolution results from the reaction of an organic hydroperoxide with an isocyanate in the presence of a surfactant. The invention is especially applicable to the expansion of polyester resins but has numerous other applications.
