Abstract
The present invention relates to a flame-resistant composition, a fiber-reinforced polyurethane composite comprising the flame-resistant composition and the use thereof. In particular, the invention describes a flame-resistant polyurethane-composite forming composition and a combustion-modified, fiber-reinforced polyurethane composite comprising the flame-resistant polyurethane-composite forming composition, for applications in vehicles and for building products. The invention also describes a long-fiber injection molding process for the preparation of the combustion-modified, fiber-reinforced polyurethane composite. The fiber-reinforced polyurethane composite of the invention show improved fire-reaction behavior, measured as Limiting Oxygen Index (LOI), and a reduced smoke production.
