FIELD: metallurgy.SUBSTANCE: prepreg layers cut out to patterns and forming solid mandrel are made from moulding mass, their shape complying with article inner cavities, Mandrels from moulding mass are made from material with high linear expansion factor and low mechanical properties and wrapped with anti-adhesion film. Prepreg blank layers are laid on prepared solid mandrels. Then, separate blanks are assembled with their forming elements into one-piece structure in the mould. Forming is performed by heating the mould with its contents. After forming, aforesaid moulding mass is destructed and removed via small-size individual holes.EFFECT: lower power input, accelerated fabrication.4 cl, 2 dwg |
