SURFACING FILM FOR COMPOSITES WITH BARRIER LAYER
First Claim
1. A fiber reinforced resin matrix composite laminate comprising:
- a) at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and
b) a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising;
i) at least one barrier layer; and
ii) at least one cured adhesive layer derived from high temperature cure adhesive;
wherein at least one cured adhesive layer is bound to the cured resin matrix; and
wherein the barrier layer(s) have a composition different from that of the cured adhesive layer(s), the barrier layer(s) have a composition different from that of the cured resin matrix, and the cured adhesive layer(s) have a composition different from that of the resin matrix.

Abstract
Fiber reinforced resin matrix composite laminates are provided comprising: at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising: at least one barrier layer; and at least one cured adhesive layer derived from high temperature cure adhesive. In some embodiments, barrier layer(s) may be substantially impermeable to organic solvents, water, and/or gasses. In another aspect, fiber reinforced resin matrix composite laminates are provided comprising: a) at least one layer of fiber reinforced resin matrix comprising a cured resin matrix; and b) a surfacing construction bound to the cured resin matrix and forming a surface of the laminate, comprising: at least one barrier layer; and at least one electrically conductive layer. In another aspect, a surfacing construction is provided comprising a barrier layer and a curable adhesive layer.
