Abstract
Polyisocyanurate systems, pultrusion of those systems to produce reinforced polyisocyanurate matrix composites, and to composites produced thereby. The polyisocyanurate systems include a polyol component, an optional chain extender, and an isocyanate. The polyisocyanurate systems have extended initiation times of about 5 minutes to about 30 minutes at room temperature, and can be snap cured.
