In a method of making a material, a bismaleimide system is heated to generate a bismaleimide liquid (). The bismaleimide liquid is degassed () to generate a degassed bismaleimide liquid. At least one of high speed shear mixing and probe sonication is performed to the degassed bismaleimide liquid to generate a highly mixed bismaleimide liquid phase (). The highly mixed bismaleimide liquid phase is cured (). A bismaleimide product is made by heating a three component bismaleimide system to generate a bismaleimide liquid, which is degassed in a 30 mbar vacuum until no new visually perceptible bubbles are detected. The degassed liquid is high speed shear mixed at a speed of 3500 RPM for 10 minutes to generate a highly mixed bismaleimide liquid phase, which is cured to make the bismaleimide product. A substance includes cured bismaleimide having an impact strength in a range of 56 kJ/mto 82 kJ/m.
