Abstract: Process for producing a fiber reinforced plastics linear material like a tension member for optical communication cables. A groove capable of accomodating an optical fiber is formed in the outer surface of the tension member. In accordance with the conventional method, the groove is necessarily formed in parallel along the axial direction of the tension member and, therefore, if the tension member is bent in the state that the optical fiber is placed in the groove, a force due to bending is applied directly to the optical fiber and the transmission loss of the optical fiber is increased.

Abstract: An optical fiber coated with a reinforcing material having an excellent heat resistance and a process for producing the same are disclosed. The reinforcing material comprises continuous filaments having impregnated therein a curable composition comprising(a) tri(meth)acrylate of trishydroxylalkyl isocyanurate,(b) a modified phenol novolak-based resin having (meth)acryloyl groups in the molecule, and(c) a polymerization initiator.
