FIELD: machine building.
SUBSTANCE: separation layer is laid onto mandrel. Said separation layer is laid section-by-section in pre-making the sections from anti-adhesion resilient material with metal inserts. Said metal inserts have holes for attaching said sections to the mandrel by fastening mounts. Said sections are fitted on said mandrel after prepreg work pieces laid thereon manually or with the help of automated placer in compliance with overlapping pattern of reinforcement. Shell skin layers, sawing block, drain layers and vacuum bag are laid at aforesaid layers. After thermal treatment, made article is withdrawn from mandrel and sections are detached.
EFFECT: higher reliability, lower costs and labor input.
