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. |
