ABSTRACT
In modern manufacturing industry of wind turbine blades [1], fibre-reinforced composite materials are chosen among other available engineering materials because of their significant and attractive advantages in terms of stiffness-and strength-to-weight ratio, thermal and chemical resistance properties, coupled with material cost effectiveness [2]. In addition to the economic advantage and technical-quality efficiency, further ecological aspects are still required in order to green up the moulding processes and this after an appropriate selection of matrix resin and fibre materials that are answering questions related to environmental and safety issues. These ecological aspects are based on balanced key criteria characterized mainly by a comprehensive consideration of environmental preservation and health protection besides quality assurance [3-5]; all of which must provide healthier, safe, clean, and sustainable process. Within this environmentally mindful context, the closed mould process provides an alter-
native solution to these requirements and satisfies the condition of green design method (i.e., ecodesign).
