20 June Página :20 Tooling requirements Dimensional accuracy in very large dimensions Dimensional stability under thermal excursion 200 ºC Durability Surface quality Compatibility with demoulding agents Easy of manufacturing, inspect and repair High thermal condutivity, low weight, low thermal expansion Tooling materials: Steel, Invar, CFRP, graphite,

21 June Página :21 Additional tooling reqs. for RTM Very stiff. The dry preform need to be packed tight Very high accuracy in thickness to control fibre volume, and to avoid dry spots. Resin injection and vacuum ports needs to be carefully positioned for a good resin flow. Once closed, vacuum level better than 50 mm Hg. O-ring seal is critical. Heater and cooling system (electrical resistances, water conducts,...) can be built-in at the tool.

22 June Página :22 Alignment according to geometrical key features. These movements are made by the positioners, taking into account a theoretical reference. BEST-FIT calculation before join-up operation. Recording of HTP reference position within a friendly graphical user interface. FLEXIBLE JIG:Placing of lateral boxes in a fixed position. After positioning the whole system can be moved. Old tooling, poor ergonomics, lead time reduction impossible Assembly tooling

23 June Página :23 Conclusions + Composite manufacturing is still a labor intensive process, for many components. + New technologies have been developed to improve the productivity and quality of the parts. + Special moulds requirements derive from the large size of the components, the thermal excursion and the sticky nature of the composite during cure.
