Polyisocyanurate Based Polymers and Fiber Reinforced Composites

A method of making an isocyanurate polymer, comprising the steps of:

• providing an isocyanate including at least one of an aromatic isocyanate and an aliphatic isocyanate;
• providing a trimerization catalyst including at least one of an amine catalyst, an organometallic compound, and an imidazole compound;
• forming a reaction mixture being substantially free of reactive hydrogen by mixing a catalytic amount of an epoxide with said isocyanate and about 0.1 to 15 weight percent of a total weight of said reaction mixture with at least one of a phosphorus ester, halogenated phosphate, siloxane, halogenated compound and metal hydroxide;
• mixing said trimerization catalyst with said reaction mixture;
• and
• curing said reaction mixture to produce a polymer composition including a reaction product of two or more isocyanates.
