Bobbin for optical fiber canisters and method of manufacturing it

摘要

An orthotropic bobbin for optical fibers is made of a composite material which comprises (I) continuous filaments having a high tensile strength and a low coefficient of thermal expansion; and (II) a polymeric matrix having a high coefficient of thermal expansion, wherein said polymeric matrix is the product of the curing of a matrix precursor composition comprising an epoxy resin, a hardener and a rubber modifier. <IMAGE>
