Determination of interfacial shear strength between the glass fiber and primary coating in double-coated optical fibers from mechanical strip forces.
We propose a method of determining interfacial shear strength between the glass fiber and primary coating in double-coated optical fibers. A commercial stripper is used to mechanically strip the polymeric coatings. It consists of two hinged arms and a pair of blades with a semicircular bore. In the mechanical stripping process the relationship between the strip force and stripper displacement is measured. The interfacial shear strength between the glass fiber and primary coating is then determined from this relationship. The measured interfacial shear strength increases with the increasing stripping rate. It is found that measured results are compatible with theoretical results.
