<p><P>PROBLEM TO BE SOLVED: To provide a method for maintaining strength enough to keep a three dimensional positioning of a crystal material having an acicular form without damaging its function by reinforcing adhered parts by any means. <P>SOLUTION: For the purpose that an uncured resin has to be well impregnated into spaces among aggregated whisker, the resin is preferably low viscous and well compatible with ZnO, which is a material of the whisker, and further the resin is necessary to be a non-solvent type in order to suppress volume shrinkage upon curing. Further, the volume shrinkage upon curing can be prevented by selecting/designing a resin generating no releasing group upon curing (e.g. an epoxy resin). Still further, a resin having a high hydrophilicity such as one having a large amount of an OH group is selected for impregnation because the surface of ZnO is generally hydrophilic due to influence by moisture in air. A linear expansion coefficient of the resin used is adjusted to one similar to that of the whisker by mixing the resin with particulates having a low thermal expansion coefficient. <P>COPYRIGHT: (C)2004,JPO</p> |
