Committee Reports Development Engineering Kevlar laminate samples have been prepared for abrasion and compressive creep tests. Additional laminate has been ordered from Hampton with delivery due in June. This laminate is the proposed replacement for asbestos phenolic 44141AJ. Kevlar materials are difficult to machine; however, it is believed this short coming will be resolved with additional development. Epoxy-coated Nomex has been ordered from Bedford and 100 yds. will be available early in May. Ceramic-glass paper samples coated with both shellac and epoxy are due late in April. Brushless Exciters - Medium Turbine Generators This group has completed the review of their asbestos usage and the following items are reported: The most probable replacement will be glass cloth edging tape from Carolina Narrow Fabrics. Additional data is being collected from the supplier to obtain a material number (John Orobne). 42341 BN - Shellac treated asbestos paper for turn insulation of strap wound field coils. - One or more of the following materials will be suitable for this application: . 41524PY(ET-1190) and similar thin glass cloth polyester resin materials are available from Bedford and are being used for similar applications at Buffalo.
