  • Composite fiberglass railcar roof
    Patent number: 5916093
    Abstract: A fiberglass railcar roof that includes a fiberglass surface with a central portion and plural elongate fiberglass ribs extending transverse to the longitudinal axis of the fiberglass surface. In a first embodiment, the central portion has a cross-sectional configuration that defines a first arc, and the ribs each have broad widths and each extend above the central portion to define a second arc that intersects the first arc. In a second embodiment, the ribs have arcuate cross-sections and extend downward from the lower face of the central portion.
