A nonporous sheet material for temporary or permanent bonding to a work piece, the sheet material comprising:a porous fabric impregnated with a resin blend in sufficient quantity to render the fabric nonporous, the resin blend comprising a blend of epoxy and thermoplastic resins; the epoxy resin being present in the blend in the range of about 35 to about 65 percent by weight and the thermoplastic resin being present in the blend in the range of about 65 to about 35 percent by weight, and the thermoplastic and epoxy resins are selected such that the resin blend softens at a temperature in the range of about 100.degree. F. to about 300.degree. F.;wherein the nonporous, reusable sheet material can be bonded to the structure by heating the sheet material to a temperature within the temperature range to soften the resin, placing the sheet material and structure in mutual contact, and then cooling the sheet material to ambient temperature.
