Abstract : An investigation of the process for manufacturing glass fiber reinforcements for filament winding plastic composite structures was completed. The data indicate that the difference between average virgin fiber strength and roving strength is 20%. Experiments were run on every step in the process from the bushing through roving, and material was tested at intermediate points. The results show that the differenc between average virgin fiber strength and roving strength in a composite cannot be attributed to any specific process operation. If there is actually a loss in fiber strength from virgin fiber to roving, presently available test methods are unable to measure it. A theory which predicts the strength of a bundle of fibers of varying strengths was proposed by several investigators. Application of this theory to single fiber data predicts that a 20% reduction from average single fiber tensile strength can be expected in glass fiber roving. (Author)
