ABSTRACT:
Pultruded fiberglass sign panels having overall and cross-section designs useful for replacing aluminum alloy highway signs are disclosed. The construction materials of the pultruded fiberglass sign panels consist of a glass roving; glass reinforcement matt; and a resin matrix. The glass content of the sign panels contain recycled or virgin glass, preferably about 16% by weight or 35% by volume of recycled or virgin glass. The resin matrix comprises thermoset isophthalic polyester that is about 42% to about 44% by weight or about 60% to about 62% by volume. The glass reinforcement matt used in the pultruded fiberglass sign panel comprises a hybrid E/A glass reinforcement matt and the pultruded fiberglass sign panel has a panel width of about 6 inches to about 36 inches, and a length of about 1 foot to about 50 feet. Two or more sign panels can be fastened together to produce a multi-panel system for making highway sign blanks. A first sign panel is fastened substantially adjacent to the second sign panel along the first or second edge forming a substantially flat sign surface on one side of the multi-panel system and a mounting surface on the opposite side of the substantially flat sign surface. The first sign panel is fastened substantially adjacent to the second sign panel using a fastener.
