Beschreibung
Zusammenfassung:	The invention relates to a process for producing a composite polyisocyanurate material, comprising the following steps: a) providing a polyisocyanate composition A) which comprises oligomeric polyisocyanates and is low in monomeric diisocyanates, "low in monomeric diisocyanates" meaning that the polyisocyanate composition A) has a content of monomeric diisocyanates of not more than 20% by weight, and b) catalytically trimerizing the polyisocyanate composition A) in the presence of at least one fibrous filler B) and of a trimerization catalyst C) to give the composite polyisocyanurate material, where the trimerization catalyst C) comprises at least one metal salt and/or quaternary ammonium salt. The invention further relates to composite polyisocyanurate materials obtainable by the process according to the invention and to the use thereof for production of a component, and to components consisting of or comprising a composite polyisocyanurate material according to the invention.
