ABSTRACT:
A covering sheet material particularly for covering balsa wood frameworks of model aircraft, comprises a fibrous scrim which is impregnated with a resin solution containing a cross-linking agent and a catalyst. The resin solution may also include a dye or pigment, coloring agent, a filler or a metal powder, to give a desired surface appearance. The scrim may be a heat bonded non-woven fabric of polyester fibres, and the covering sheet may be bonded to the framework using a heat seal adhesive. After bonding, the covering material may be tautened by further heating. The covering material is lighter, stronger and more puncture resistant than conventional doped tissue paper covering materials.
