Lay-up and Stacking

Higher volume production at constant quality

The most basic and oldest fabrication method for thermoset composites is hand lay-up, which typically consists of laying dry fabric layers by hand onto a tool to form a laminate stack.

Today, most composite parts are draped manually and in order to meet increasing production rates, we totally re-examined this production process by developing an automated technology capable of taking one or more plies from an initial reference and placing them in their final position (flat or 3D) according to the lay-up plan (SMART Pick & Place).

Our SMART Control solution can complement the SMART Pick & Place in order to check at 100% the confirmity of the draping.
