Microscale sensor solution for data collection from fibre-matrix interfaces

Abstract Especially the applications of fibrous composites in miniature products, dental and other medical applications require accurate data of microscale mechanics. The characterization of adhesion between single filament and picoliter-scale polymer matrix usually relies on the experiments using s...
