Abstract:

Data on the strength properties of glass roving reinforced plastics is discussed. Experimental glass formulations were used in the preparation of test specimens which were evaluated by the series of NOL Ring Test methods. Results show that much progress was made in the development of higher modulus fibers for reinforced plastics. A tensile modulus of 13.4 x 10 to the 6th power psi was obtained with YM-31-A in a ring. Calculated to a 100 glass basis, the modulus of the glass was 17.6 x 10 to the 6th power psi, which compares well with 17 x 10 to the 6th power psi reported in literature. Author
