Unfortunately, there are also many disadvantages to hand lay-up. The most obvious is the labour cost. In addition, the application of the resin in an open environment allows very volatile emissions to escape from the resin that can be harmful to humans and to the environment (Skramstad, 1999). It is anticipated that the use of hand lay-up for wind turbines will eventually be restricted due to the high volume of emissions. Other disadvantages are lower dimensional tolerances, poor fatigue performance, and less aerodynamic surfaces.

In this process the 3-D non-woven products were produced directly from staple fibres using the air-laying principle. The fibres were deposited onto 3-D porous moulds before the fibrous web was consolidated to produce the final product. The web-forming process is schematically shown in Fig. 23. The machine width was 1245 mm and the length of the upstream air duct was 1600 mm from the opening unit to the mould chamber. The fibres opened by the opening unit were transported by airflow through the upstream duct to the mould chamber, which had a vertical depth of 300 mm.

In the simplest case, woven fabrics can be replaced by stitched fabrics, maintaining the same fibre count and orientation. Stitch-bonded multi-plies Multi-plies are fabrics consisting of one or more parallel and drawn layers of threads that can have different orientations. Stitch-bonded, multiaxial © Woodhead Publishing Limited, 2008 24 3-D fibrous assemblies fabrics or, simply, stitched fabrics consist of several layers of unidirectional fibre bundles held together by a non-structural stitching thread, usually polyester.
