Abstract : This patent involves a method of encapsulation that comprises covering the article to be encapsulated with an epoxy resin containing discontinuous graphite and/or boron nitride fibers, and curing the epoxy resin, thereby obtaining a product having a low coefficient of linear thermal expansion. The method is particularly useful for encapsulating delicate electrical, optical and mechanical elements that are incapable of withstanding thermal stresses.
