Patent
CA 2188184
A composite material and a method for making same are disclosed. A composite article including an electrically and/or thermally insulating substrate and protective layers on each side thereof is particularly disclosed. Said material includes protective layers consisting of fibres of a heat-stable material flocked onto the insulating substrate, and a heat-stable coating resin. The resulting protective layer has improved protective properties, particularly moisture-proofness. The composite material may also be used as a metal layer carrier for forming flexible printed electrical circuits.
L'invention concerne un materiau composite et un procédé de fabrication de celui-ci. Elle concerne plus particulièrement un article composite comprenant un substrat électriquement et/ou thermiquement isolant et des couches protectrices de ce substrat disposées sur chaque face de celui-ci. Ce matériau comprend des couches protectrices formées par des fibres en matériau thermiquement stable floquées sur le substrat isolant et une résine d'enduction thermiquement stable. La couche protectrice ainsi formée présente des caractéristiques de protection, notamment d'étanchéité à l'humidité, améliorées. Ce matériau composite peut être également utilisé comme support de couche métallique pour former des circuits électriques imprimés souples.
