PULTRUSION OF PROFILES HAVING A NON-UNIFORM CROSS-SECTION Russian patent published in 2022 - IPC B21C23/14 B21C25/02 B29C70/52 

Abstract RU 2782086 C1

FIELD: composite materials.

SUBSTANCE: invention relates to the manufacture of profiles from composite materials, such as rotor blades, aerodynamic profiles, I-beams and box beams having a non-uniform cross section. Pultrusion of the thickened part of the leading edge of the composite profile is carried out on the same line and along the course before pultrusion of the thinner or lighter main part of the profile. In this case, a separate head is used for the thickened part of the leading edge of the profile.

EFFECT: as a result, optimization of processing conditions, productivity and quality stability of composite profiles is ensured.
