Book Description
Three plastic laminates reinforced with unwoven, unidirectional glass fibers were evaluated over varying spans under both midpoint and two-point loading improve accepted flexure test procedures for these materials. Also investigated were the effects of radius of loading nose, length of overhang, and different two-point loading systems on properties of 1/8-inch laminates. Results of these evaluations indicated that present test methods often result in failures that do not accurately evaluate the outer fiber strength of the material. Horizontal shear failures could be eliminated by using a specimen with a span-depth ratio greater than 16. For a long specimen, a correction factor must be applied to the conventional moment expression to include the effect of horizontal components of force at the reaction supports. Compression failures beneath the load points were eliminated either by using a 0.01-inch-thick metal plate beneath a loading nose of 1/8-inch radius, increasing the loading nose radius, or increasing the specimen spandepth ration.
