SYSTEM FOR FORMING STACKS OF COMPOSITE MATERIALS

摘要

The invention relates to a system for shaping laminar composite materials, comprising a base (1) with at least one longitudinal mandrel element (2) comprising a shape to be given to a stack of composite material (3) arranged on the mandrel element (2) for obtaining a formed stack (3′) of composite material, and at least one pressure rolling forming device (4) assembled in a support carriage (5) such that it is capable of placing the pressure rolling forming device (4) in at least one position in which it rolls over the stack of composite material (3) pressing it against the mandrel element (2) for forming it and obtaining the formed stack (3′), the pressure rolling forming device (4) comprising a rolling hollow cover (4a) made of elastically flexible material with a tread (4b), and the rolling hollow cover (4a) being susceptible to containing: a fill fluid at a fill pressure and/or a plurality of particles (27) which allow the tread (4b) to elastically adapt to the shape of the mandrel element (2) and exert a chosen pressure on the stack of composite material (3).

1. System for forming stacks of composite material comprising a base (1) with at least one longitudinal mandrel element (2) on its upper face, comprising a shape to be given to a stack of composite material (3) which is arranged on the mandrel element (2) for obtaining a formed stack (3′); and at least one pressure rolling forming device (4) assembled in a supporting device (5) and susceptible of being placed in at least one position in which it rolls over the stack of composite material (3) pressing the stack of composite material (3) against the mandrel element (2) for forming it and obtaining the formed stack (3′); characterized in that:
the pressure rolling forming device (4) comprises a rolling hollow forming cover (4a) made of flexible material with a tread (4b); and the rolling hollow cover (4a) is susceptible to containing at least one fill fluid at a fill pressure which allows the tread (4b) to elastically adapt to at least part of the mandrel element (2) and exert a controlled pressure on the stack of composite material (3).
