METHOD OF PRODUCING REFERENCE VANE PIECE FROM COMPOSITE MATERIALS

摘要

FIELD: process engineering. ^ SUBSTANCE: invention relates to fabrication of vane reference piece from composite material for standardising X-ray control over similar vanes. Proposed method comprises forming solid billet woven from synthetic fibers and making cavities in selected points of said billet. Then, said billet is placed in mould to force resin therein to make aforesaid reference vane piece. Note here that aforesaid cavities are formed by introducing expansion appliances into selected points of fibrous structure to displace fibers. ^ EFFECT: higher efficiency and detecting defects in vanes. ^ 3 cl, 5 dwg
