The production of modern wind turbine blades has become increasingly complex with the introduction of 15+ MW turbines, where blade lengths now exceed 100 metres. This places significant demands on manufacturers to achieve “right-first-time” quality in the vacuum infusion process while maintaining high productivity and controlling costs.
For such large FRP composite components, uneven resin distribution, premature resin curing, dry laminate areas, and trapped air voids present a serious risk. Infusion failures can result in rejected blades, extended cycle times, and substantial financial losses. The large size and high aspect ratio of today’s blades make consistent resin flow and effective air removal—especially in narrow sections and blade extremities—more challenging than ever.
EXPO-NET Danmark A/S works closely with wind turbine blade manufacturers and OEMs to develop customised resin flow mesh solutions tailored to each specific blade design and production process.
By engaging early in OEM New Product Development (NPD) projects, EXPO-NET supports both design and process engineers through multiple testing and trial phases. Different combinations and specifications of resin flow mesh are evaluated and refined until optimal resin flow, air removal, and infusion consistency are achieved.
For longer blades, EXPO-NET recommends using a combination of flat, drapable fine mesh and heavier wide tubular flow mesh in selected areas. The tubular flow mesh acts as a highly effective air evacuation channel, significantly improving air removal from narrow laminate sections and blade extremities while also accelerating resin distribution.
Once approved, the specified resin flow mesh solution is supplied globally, supported by buffer stock and close coordination with OEMs and strategic kitting partners.
The implementation of customised EXPO-NET resin flow mesh solutions delivers measurable improvements in productivity, quality, and cost efficiency for wind turbine blade manufacturers.
Customers benefit from:
The productivity gains ensure that the additional investment in tailored flow mesh solutions can be recovered within a short period, resulting in improved profitability. At the same time, the use of 100% recyclable thermoplastic mesh supports more sustainable composite manufacturing.
