Carbon Nanotubes – a Game Changer in Reinforcing Composites

The study by the Institute of Polymers and Composites at Hamburg University of Technology (TUHH) analysed a hotmelt epoxy prepreg system that was modified with an industrially available masterbatch containing TUBALL™ single wall carbon nanotubes produced by OCSiAl.

The neat and modified CFRP were subjected to ordinary service conditions, specifically an impact of 28 J. Specimens modified with 0.05 wt.% of nanotubes recorded a significant reduction of delamination area by 19%. Additionally the compression after impact strength was increased by around 5%.

Results achieved have encouraged the Hamburg University of Technology to continue testing of advanced high-performance materials created with the use of TUBALL single wall carbon nanotubes. Large manufacturers are running industrial trials. Further results will demonstrate even higher potential for high-grade composites for a wide range of applications.

At JEC World 2017 in Paris, Hall 5A, booth G23, OCSiAl will showcase its core product – TUBALL nanotubes – and the advanced nanotube-based modifiers that are now available for a variety of materials. Next-generation nano-augmented materials that have already been successfully commercialized will also be on show.
