METHOD OF PRODUCING STRUCTURAL COMPONENT FROM COMPOSITE MATERIAL REINFORCED BY FIBRES FOR AEROSPACE ENGINEERING, MOULDING CORE FOR PRODUCTION OF SAID COMPONENT, AND COMPONENT THUS PRODUCED AND/OR BY MEANS OF SAID CORE
METHOD OF PRODUCING STRUCTURAL COMPONENT FROM COMPOSITE MATERIAL REINFORCED BY FIBRES FOR AEROSPACE ENGINEERING, MOULDING CORE FOR PRODUCTION OF SAID COMPONENT, AND COMPONENT THUS PRODUCED AND/OR BY MEANS OF SAID CORE
FIELD: process engineering.;SUBSTANCE: set of invention relates to structural component from composite material reinforced by fibres for aerospace engineering, moulding core for production of said component, and to moulding core for production of said component. Proposed method comprises the following stages. Producing moulding core with preset number of hollow elements to define its outer shape. Note here that said hollow elements are arranged in lengthwise direction of moulding core and secured to each other to allow elastic expansion. Note also that produced moulding core has elastic outer layer for leveling its outer surface contour and core shell intended for isolation from structural element being produced. Then, biller from material reinforced by fibres is placed on produced moulding core to shape structural element section as required. Now, said section is subjected to heating or pressure effects.;EFFECT: ease of withdrawal Q-shape stringers, lower weight of structural component.;23 cl, 6 dwg
