Expo-Net vacuum infusion products improve composite part quality, productivity
JEC World 2026: Two novel products, flexible resin flow meshes and breathable micro-porous peeling materials, establish Expo-Net’s ability to provide “right first time” composites production to customers.

Expo-Net Danmark A/S (Hjørring, Denmark) is showcasing two products specially developed for molders producing medium to large composite parts by vacuum infusion. The company has an established reputation as an innovative, highly technical, problem-solving producer of resin flow mesh products which improve infusion productivity and aid “right first time” production of large composite parts.
Infusion development trials with a number of customers looking to use a resin flow mesh with better drapability has resulted in Expo-Net now offering the composites market two flexible resin flow meshes with rubbery properties:
- Quick Flow 156/160M, a blue, drapable, ~1.5-mm-thick flow mesh for rapid vacuum infusion of larger parts (see opening image).
- Medium Flow 101, a thinner white mesh, only ~1.1 mm thick, with even higher drapability that is ideal for molding smaller, more complex-shaped curved parts.
Expo-Net extruded resin flow meshes are made from 100% recyclable PP, with grades developed for use in specific areas of an infused part.
Both drapable meshes are 100% recyclable — they are extruded using a specially formulated, low-density polyethylene (LDPE)-based thermoplastic polymer blend.
Expo-Net also features a product collaboratively developed with Fibertex Nonwovens A/S (Aalberg, Denmark). Compoflex RF4 is a new addition to the Fibertex range of breathable micro-porous peeling materials, designed to enable manufacturers of FRP components using vacuum infusion to replace up to three consumables — peel ply, release film and breather — with a single layer.
The high-speed polypropylene resin flow mesh specified in Compoflex RF4 is custom manufactured by Expo-Net for Fibertex Nonwovens. Along with process time and cost savings, Compoflex RF4 provides a controlled flow front, produces a higher surface quality and because of easy peeling minimizes resin dust on the shop floor.
Expo-Net’s resin flow mesh products and infusion technical expertise have benefited leading wind blade producers for more than 25 years. Further information and technical advice about both products is available to attendees.
