PURPOSE:To enable the maintenance of a constant density of proton for a long term by diffusing silicate material into thermosetting resin. CONSTITUTION:The textile fabric, knitted fabric or nonwoven fabric of long glass fibers 1 is distributed in the shape of a mat in thermosetting resin 2. As silicate material similar to the fibers 1, short glass fibers 3 and the powder of glass fibers are used other than the fibers 1. A variety of test plates for NMR having different density of proton from each other can be formed according to the state of diffusion of each material. |
