Inventor: MURAKI TOSHIO
IPC: D06M101/40
Filed: 1995-03-23
Abstract: PURPOSE:To prevent precipitation of a matrix resin of a surface layer into a carbon fiber fabric to keep tackiness as a prepreg for a long time by a method wherein a form stabilizer is loaded by a predetermined percentage by weight per the total weight of the fiber material of the fabric. CONSTITUTION:A form stabilizer is loaded to a carbon fiber fabric in the amount of 0.5-10wt.% per the total weight of the fiber material of the fabric. After that, the carbon fiber fabric is impregnated with an epoxy resin composition to be formed as required prepreg. Alternatively, while or after a carbon fiber fabric loaded with a low-temperature curing agent for an epoxy resin is impregnated with an epoxy resin composition, a part of the epoxy resin composition is cured by the curing agent to be formed as a required prepreg. As the carbon fiber fabric used in this case, a two--dimensional fabric obtained by weaving a carbon fiber roving is used.

Filed: 1983-04-12
Abstract: PURPOSE:To detect the amount of transformation and flatness of a steel material by arranging an exciting coil on one side of the steel material to be measured and plural detection coils at different positions, and processing detection signals from the detection coils. CONSTITUTION:When the steel material is in gamma single phase, pieces 141 and 142 of magnetic flux interlinking with the detection coils 151 and 152 through the exciting coil 13 excited by an AC exciting device 12 are generated with intensities corresponding to distances l1 and l2 from the exciting coil 13 and voltages proportional to them are induced. When alpha-phase precipitation by transition from gamma to alpha occurs to the steel material, the steel material 1 varies in magnetic field intensity and the pieces 141 and 142 of magnetic flux vary in initial intensity, and the variations are detected as variations in induced voltages across the detection coils 151 and 152. Further, when lift-off (flatness) variation is caused, the induced voltages across the detection coils 151 and 152 vary. Detection signals 161 and 162 are transmitted to an arithmetic device 17 and processed to calculate the amount of tranformation and flatness in the steel material 1.
