About the course

The design process is covered in two stages:  a “Preliminary Design” stage in which the composite part is designed at a conceptual level by defining “Zones” of uniform laminate on the reference surface, and defining transitions where the thicknesses vary; and a “Detailed Design” stage where the preliminary design data is efficiently used to create a “Stacking” of individual plies. You will also learn how to prepare the design for manufacture by analysing and modifying the plies, individually or in multiples, to design-out the potential manufacturing issues that can come from poor draping or incorrect ply stack ordering.

The Design & Manufacturing Prep (CPE & CPM) topics are covered together in this course over 4 days.  However, DTE can offer training in Design only (CPE) over 3 days, and Manufacturing Prep only (CPM) over 2 days on request. DTE can also offer training in the Composite Grid Design approach (CPG).



  • Become familiar with the CATIA Composite Design workbench interface.
  • Create a catalog of Composite materials.
  • Define the composite parameters (materials, ply orientations, laminates).
  • Define a zone-based preliminary design.
  • Define zone laminates in MS Excel and import into the Zone definition in CATIA.
  • Create solids / top surfaces from zones.
  • Define the ply stacking sequence in MS Excel and import into CATIA.
  • Create plies from the zone definition (with pre-defined stacking sequence), or create individual plies manually without zones.
  • Define and incorporate composite cores.
  • Define the ply staggering in MS Excel and import into CATIA.
  • Verify the design using the Core Sampling, Ply Exploder, 3D Sectioning, and Numerical Analysis tools.
  • Analyse the plies with the Producibility Analysis tool (draping analysis).
  • Modify plies based on producibility analysis results.
  • Engineering / Manufacturing surface swapping.
  • Add excess materials to plies for edge trimming.
  • Ply flattening.
  • Ply book generation and export of DXF/IGS files.
