AIREX T10, the industrialised PET foam core, more cost-effective than alternative foam materials for wind turbine blades

Tuesday, July 09, 2019 by 3A Composites Core Materials

AIREX T10 is a closed-cell, thermoplastic and recyclable polymer foam with a very homogeneous cell structure, high mechanical properties and an outstanding price / performance ratio.

It has an extraordinary resist-ance to fatigue, is chemically stable, UV-resistant and has negligible water absorption. It is thermally stable during high temperature processing and post curing without after ex-pansion or out-gassing. T10 is designed for easy use with all resin systems and processing technologies.

AIREX T10 is ideally suited for high volume applications of lightweight sandwich structures subjected to static and dynamic loads and/or exposed to elevated tempera-tures during manufacturing.
