Pales d'éoliennesIndex. décimale : 668.4 Plastiques, vinyles Résumé : The recovery of energy from renewable sources is a primary goal today and wind energy provides significant opportunities with only modest environmental effects. Yet, the very efficiency of wind energy systems can significantly alter the economics of this approach to energy harvesting. Advances in design and manufacturing technology for composite structures will provide the foundation for enhancing the energy and structural efficiency of wind blades.

Technique de la productionIndex. décimale : 668.4 Plastiques, vinyles Résumé : Wind turbine blades are usually made of long fibre-reinforced composites. The reinforced fibres are processed into high-performance technical textiles made up of glass and carbon fibre material, almost exclusively so-called multiaxial non-crimp fabrics (NCF). Automating the process used to handle limp materials like NCF can reduce process uncertainties and increase quality. Two different manufacturing strategies for the automated production of wind turbine blaes are described in this article. Note de contenu : - Large area preforming
- Direct textile layup

Pales d'éoliennesIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The use of wind energy is expected to grow at an unprecedented rate. Developments in wind energy are presenting new challenges to designers and engineers. For example, with a demand for increase in wind turbine blade size comes an exponential increase in the performance requirements of the materials used. Research continues in the use of structural adhesives to bond composite wind turbine components. ITW Plexus is a leader in this field, and its work is benefitting a number of manufacturers.
Turbine blades are traditionally bonded with relatively slow-curing epoxy systems, polyesters and two-part polyurethane adhesives. ITW Plexus has developed long-working-time, fast-curing, 1:1 methacrylate structural adhesives that produce bonds that hold after the substrates delaminate. Unlike traditional adhesives, these advanced methacrylate adhesives chemically fuse FRP/GRP, composite stiffener spars and perimeter flange joints. They also provide increased peel resistance and cycle fatigue resistance while reducing damage during transportation. Room-temperature snap-cure properties have helped to increase production rates and eliminate the expenses and energy costs associated with post curing, which is required to cure some epoxies. What’s more, little or no surface preparation is required.
The company’s MA560 and MA590 adhesives have gained acceptance in this growing marketplace because they also increase blade performance and reduce processing time.Note de contenu : - DESIGN REQUIREMENTS FOR TURBINE COMPONENTS AND ADHESIVES : 1.

Temps de cycle (production) -- RéductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : Wind turbines are getting bigger and bigger, and the industry is challenged for more cost reductions and higher production efficiency. At the same time manufacturers are facing high quality criteria that come at cost. Rotor blades are typically almost a third of the cost of a turbine, and currently have a high labour content in the manufacturing process. The obvious question which come to mind is : "Can the manufacturing process be automated ?"

The value propositions for new and emerging technology are enabling wind industry evolution. However, when reviewing the history of wind blade technologies, it is clear that the small evolutions may turn significantly disruptive to the industry. To keep up with the trends of the evolving industry, it is crucial to understand the past developments and identify potential new technologies arising in the next five to ten years.
