ABSTRACT:
A flexible resin and fiber composite street sign blank adapted for attachment to a rigid bracket and signpost. The sign blank comprises a planer web section whose material composition and fiber arrangement provide a tensile strength of at least 25,000 psi and preserve flexibility to enable the sign blank to withstand impacts and other destructive influence. The web section is bounded along one or both of its long sides with an elongate rail section which has at least twice the thickness of the web thickness. The rail section has a material composition and fiber arrangement which provide a minimum tensile strength of at least 40,000 psi and develop an improved compliance match for attachment at the rigid bracket and signpost.
