Glass-Fiber Reinforced Polyester Lining

摘要

Information from an experimental field installation of onsite manufactured (cast-in-place) glass-fiber-reinforced polyester resin canal lining indicated that the lining as installed was not satisfactory. However, the process with further development has definite possibilities for canal lining. Laboratory tests of field test sections of cast-in-place and precast glass-fiber-reinforced polyester lining indicated that the material contained flaw areas of resin not saturating the glass mats, resulting in structural weakness and high water permeation. Test samples of flow-free areas showed that the lining was watertight, tough, strong, and similar to reinforced plastic structural panels used in roofing and skylight construction. Durability of the lining will be determined by periodic examinations of field test sections. (Author)
