Bicomponent Polymer/Glass Fibres for Stamp Forming
Coating individual glass filaments with a thermoplastic sheath is proposed as an alternative concept to existing hybrid intermediate materials to facilitate the high volume production of thermoplastic composites. The intimate contact between fibre and matrix in bicomponent fibres provides full wetout of the fibres while retaining the draping possibilities of the unconsolidated rovings. To manufacture such bicomponent fibres, we propose a dip-coating process incorporated in-line with glass fibre spinning facilities. Here, an experimental proof of concept for dip-coating single filaments in dilute polymer solutions is given.
