Axson is offering a new generation epoxy system dedicated to the resin infusion process, in the field of boatbuilding, aeronautics, railways, windmill and automotive industries.
Axson, global supplier of solutions for the high performance composites industry, regards itself to be the only group to propose a global solution from the production of the model in extrudable paste, to the infusion of both moulds and parts, and their final assembly.
”Axson announces its ambition to double its activities regarding high performance composite materials in the four coming years”, reveals Patrick Blosse, Axson International Development Manager.
The resin infusion consists of sucking under vacuum a low viscosity resin through reinforcements placed between the rigid part of a mould and a vacuum bag, insuring the airtightness of the whole. This technology, together with the correct choice of materials, enables the production of durable and efficient parts with the quality achieved competing with the one obtained with the that of prepregs (low porosity content, superior wetting of the fibres…), and without the use of an autoclave.
Compared to usual wet lay-up techniques, the resin infusion allows a rigorous control of the resin to fibre content, together with a great flexibility in the work organisation. The resin infusion is overall more economical than the prepreg technique (cheaper tooling materials, lower investments…).

The American Composites Manufacturers Association participated in a roundtable discussion about the IMAGINE Act. Known as the Innovative Materials in American Growth and Infrastructure, Newly Expanded (IMAGINE) Act, the new bill is designed to promote the increased use of innovative materials like fibre reinforced polymer (FRP) composites, as well as new manufacturing methods to accelerate the deployment and extend the life of infrastructure projects.
After the collapse of a drinking water pipeline in downtown Amsterdam, the Netherlands, Insituform was contracted to reline a close to 100 year old pipe underneath one of the canals. Water was restored successfully within five days, with minimal impact on traffic and the environment.
Australian organisations Austrak, Laing O’Rourke and the University of Southern Queensland (USQ) have joined forces to develop polymer composite solutions for bridge transoms in a $10 million project titled Polymer Composite Transoms for Rail Bridge Deck Replacement (CompTrans).
