Development of Composite Constructions with Improved Rain Erosion Resistance
Abstract
This report describes the continued investigation of composite con- structions with improved rain erosion resistance. The studies included the effect on the rain erosion resistance, as determined by whirling arm tests, of such variables as fiber angle, impact angle, matrix, reinforcement, and reinforcement configuration. Matrices evaluated included a rigid epoxy, a polysulfone and a phenoxy. Reinforcements included Nomex, Kevlar, Dacron and combinations of ECG or SCG glass with Dacron and Nomex, respectively. Much of the work involved the effect of fiber angle and impact angle on the rain erosion resistance of end-oriented Nomex/epoxy composites. Based on these test results, composite constructions fabricated from several multidimensional Nomex-glass fabrics were evaluated for rain erosion resistance. The test results show that, with respect to rain erosion resistance, the multidimensional constructions are superior to the conventional glass fabric-reinforced laminated composites but inferior to the unidirectionally-reinforced, end-oriented composites.
