The main goal of PUL-AERO is the development of a material state based controlled pultrusion process for the manufacturing of curved and partially cured stringers that comply with the stringent specifications of the aerospace industry and offer significant savings in production costs.PUL-AERO will design and build a pultrusion line for the production of linear and curved composite stringers for th ...

"Today, advanced composites use either layers of plies impregnated with resin (pre-pregs) to form a laminate, or Liquid Composites Moulding (e.g. RTM) of dry textiles. Prepreg composites give superior mechanical properties due to toughened resins and high fibre content, but suffer from high material costs, limited shapeability, complex, expensive and time consuming manufacturing, and limited mater ...
