Abstract (en)

[origin: WO2021081154A1] A method of producing a reinforced polymer composite includes placing reinforcement solids a die defining a die cavity. A liquid reaction mixture including an aromatic polyisocyanate and initiating reaction of said aromatic polyisocyanate is infused with a catalyst composition forming an aromatic isocaynurate based polymer reaction mixture impregnates the reiforcing solids with using the cavity for forming the aromatic isocaynurate based polymer reaction mixture. The cavity defined by the die is heated to at least 80°C for a period required to form a polymer reaction product producing the reinforced polymer composite.
