METHOD FOR MANUFACTURE OF MOLDING EQUIPMENT OF POLYMERIC COMPOSITE MATERIAL Russian patent published in 2002 - IPC

FIELD: molding of articles of polymeric composite material, applicable for molding and cementing of integral and three-layer spatial articles, for example, airplane fuselage panels, wing. SUBSTANCE: method consists in division of the article surface into plane sections and sections of their conjugation with intervals corresponding to the intervals between the cross-sections of the article. A set of ribs is manufactured of rigid sheet material, and a bearing system is produced by fixing the produced ribs with intervals on a stiff base. Blanks corresponding to the plane sections of the article surface are cut out of rigid plate polymeric composite material. Blanks corresponding to the divisions of the sections of conjugation of the article surface plane sections are cut out of flexible sheet polymeric composite material similar in composition. The blanks cut out of rigid plate and flexible sheet polymeric composite material are laid out and fixed on the bearing system. The blanks are joined together with the aid of cement. Additional reinforcing layers of flexible sheet material or prepreg are cemented on the surfaces of conjugation of the plane sections with the whole surface of the shell until its preset thickness is obtained. Then, the adhesive joint is cured. EFFECT: provided manufacture of a spatial large-size equipment without an additional mechanical treatment, unnecessary manufacture of the article model. 6 dwg
