® reinforcement is co-mingled strands of
glass & thermoplastic fibers. twintex ® roving can
be processed directly to make a composite part,
or can be transformed into an intermediate format
for final processing in a second step. All twintex ®

reinforcement processes allow molding of components
with good mechanical properties thanks to long or
continuous fibers. glass ratio can reach 75% by
weight.

Vacuum Bagging materials that are pre-impregnated with resin are
typically laminated with vacuum bagging. the
components include a film or fabric, breather medium
& plastic film that is applied in sequence on top of
a laminate stack in an airtight mold. Air between
the mold & film is extracted with a vacuum pump,
resulting in a positive-pressure force; this compression
forces air & excess resin from a composite laminate
or components. Vacuum bagging is also used in
conjunction with other processes such as infusion
molding & wet lay-up.
