Abstract : Engineering evidence supports the belief that performance of filament wound glass reinforced plastics structures is limited by interlaminar shear resistance. Different mechanical techniques were devised, which for a given composite system, lead to significant improvements in interlaminar shear strength. This was demonstrated on uniaxially wound NOL Rings: first, when very small fibers and/or whiskers were incorporated into the resin in low percentages and, second, when fiberfoamed glass roving was used as the basic reinforcement. However, it was noted that some loss in compression modulus must be suffered. (Author)
