Setup and application of a wetting property measuring instrument

  • A new wettablity instrument was developed according to the fabrication characteristic of composites, which could measure the mass increase in fibres penetrated by resins. The instrument was composed of two parts. One was the wicking mass testing system and the other was a temperature-controlled system. It could measure the capillary impregnation of liquids in the fibre bundles with various fibre volume fractions under different temperatures. The instrument was evaluated and adjusted. Based on this, the wetting of resins in glass fibres and carbon fibres were studied. Effects of the type of fibres, the viscosity of resins and the fibre volume fraction on wicking behaviour were also investigated. The results show that this instrument provides a convenient tool for studying on wettability of the reinforced fibres probe by the resin matrix, which is valuable for guiding parameters in the process of composites.
