Pultrusion with resin transfer molding (RTM) Rainer Eberle Zürich University of Applied Sciences, Austria The name pultrusion combines the words, “pull” and “extrusion”. Pultrusion technology represents the only method currently capable of producing automatically structural composite parts on a continuous basis and of unlimited length. In the pultrusion process, reinforcing materials in the form of dry unidirectional fibers, woven or non-crimp fabrics are continuously pulled from creel racks. This collation of dry reinforcing fibers then passes through forming cards, before entering a heated steel mold. Resin is applied to the preform, either by pulling through a wet-bath or by injecting the resin directly into the die. Due to this pulling, the fiber filaments are in tension when curing in the heated die. While in tension, the fibers have higher strength values and are more aligned, allowing good compaction and more fibers fitting into a given gravity. The mold forms and compact the material into the final geometry. A pair of hydraulically-activated gripping plates is used to alternately grab and pull the material through the system at a constant speed. The profiles then periodically cut with a cut-off saw. Human interface, for example by hand-lay-up is eliminated and therefore the quality is not a function of motivation of factory technicians. Within the composites industry, pultrusion is one of the fastest rising processes for composite parts because it is a highly cost …

Question by Robert R: what perfomance differences are there between commodity grade resin and engineer grade resin?
Plastic injection molding… what factors are there between the differences in perfomance wise???

Best answer:

Answer by mike1942f
More trash, wider specifications and more variability within the specifications from batch to batch. The trash might cause weaknesses and the variability might cause manufacturing problems.
