The report shows by regression equations and charts of response surfaces the relationships between five resin system parameters and 18 physical properties of the resins. The results are based on 31 experiments arranged in a Central Composite Design for each of seven hardeners. Statistical techniques were used for designing the experiments and interpreting the results. The results indicate that the type and amount of hardener used are the most im portant of the parameters studied in effecting changes of properties, especially for those resin systems that contain amine hardeners. The relationships that exist between the physical properties of the resins and those of a filamentwound composite were investigated through the fabrication and bursting of 70 pressure vessels and short-span flexural tests of samples from 140 Naval Ordnance Laboratory type rings for interlaminar shear-strength determinations.
