FIELD: process engineering.

SUBSTANCE: invention relates to production of composite element and device to this end. Stack of plies is assembled on stacker table. Note here that every said ply comprises multiple reinforcing elements, for example, dry fibres. First part of said stack is bonded to produce partially bonded stack of plies while second part of said stack is no bonded. Partially bonded stack is formed inside mould cavity between two parts of said mould to obtain formed blank. Note also that plies in second part of said stack slide relative to each other at forming. Liquid bonding material is fed into formed blank in mould cavity for it to be solidified.
