Abstract
A non-metallic explosion vent is provided for protecting a confined space from a high overpressure condition. Reinforcing material having greater tensile strength than the resin, such as glass fiber roving, mesh or fabric, is embedded in the panel. An elongated, overall U-shaped groove extends inwardly from one of the surfaces of the panel through only a portion of the thickness of the panel. The groove interrupts the reinforcing material and defines a line of weakness that presents a relief area of the panel that opens under a predetermined overpressure condition. A plurality of spaced reinforcing components preferably overlie the groove, and optionally may extend across the relief area of the panel, transversely thereof and at an angle to one another. The reinforcing components contribute to control of the burst pressure of the vent and assist in preventing separation of the vent area from the body of the panel and/or fragmentation of the vent area during opening thereof.
