MODES OF FAILURE OF GLASS FIBER REINFORCED PLASTICS UNDER COMPRESSIVE LOADS.
Abstract
Parallel filament glass fiber reinforced plastics, having achieved notable success when used in members loaded primarily in tension, are being considered for high performance structures loaded primarily in compression. Previous work on compressive behavior both analytical and experimental, is reviewed. An experimental investigation is reported of the strengths and modes of failure of parallel filament ring segments loaded in compression parallel to the fibers in a special fixture designed to prevent gross buckling of the specimen. The observed modes of failure can be grouped into two categories: (1) failures that were initiated by local (microscopic) crippling (buckling) of individual filaments, and (2) failures that were initiated by crippling of the ends of the specimen acting as a unit. Final failures frequently exhibited crumbling of the composite ends, longitudinal splitting, and crippling of groups of fibers adjacent to the grips which sometimes resulted in 45 deg. 'shear' failures. (Author)
