Proving nanofibre performance in composites


A big congratulations to our Nanofibre Applications Engineer, Dr Gareth Beckermann, for having his recent paper published in the prestigious Composites A Journal: (this is a new link to those who couldn’t access the paper before)

Gareth investigated the effects of Xantulayr in two composite failure modes, comparing it with alternative materials and commercially available veils. Xantulayr was a standout performer.

Thanks to Waikato University, Kim Pickering, for the expertise and use of the testing facilities.

In this study, the effects of interleaved nanofibre veils on the Mode I and Mode II interlaminar fracture toughness (ILFT) of autoclave cured unidirectional carbon/epoxy composite laminates were investigated. Various electrospun nanofibre veils consisting of a range of different polymer types, fibre diameters and veil architectures were placed in the laminate mid-planes, which were subsequently subjected to double cantilever beam and end-notch flexure tests. It was found that the polymer type and veil areal weight were the most important factors contributing to laminate performance. A 4.5 g/m2 veil provided the best all-round performance with fracture toughness improvements of 156% and 69% for Mode I and Mode II, respectively.
