From the author: Tensile creep data have been obtained at 23 [degrees] C as a function of physical age from test pieces of glass fiber reinforced polypropylene cut from injection molded square plaques in directions parallel and transverse to the flow direction. Smaller compliances were measured for loading parallel to the flow than for loading in the perpendicular direction, reflecting the preferential alignment of the fibers with the flow. Two creep functions have been used to model the creep behavior over both a limited timescale where the age of the test piece remains effectively constant and a wider timescale where significant further aging of the material occurs. The results of these analyses reveal significant differences between modeling injection molded polypropylene and compression molded material.
