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

Fiber reinforced resin coated optical fiber and process for producing

A coating material for optical glass fibers is disclosed. The material is comprised of 1,4-polybutadienes having functional groups or modified polybutadienes derived from the 1,4-polybutadienes having introduced therein polymerizable double bonds different from the double bonds present in the 1,4-polybutadienes.

Optical fibers coated with modified 1,4-polybutadienes

A reinforced plastic molding having excellent heat resistance, toughness and adhesion property to a fibrous substrate is disclosed, comprising a fibrous substrate having impregnated and cured therein a curable composition comprising tri(meth)acrylate of trishydroxyalkyl isocyanurate, a modified phenol novolak-based epoxy resin and a polymerization initiator.

Reinforced plastic molding

Coated optical glass fibers are described, wherein the coating composition comprises an unsaturated polyester containing at least one of (1) polyethylene glycol or polypropylene glycol having an average molecular weight of from 200 to 1,000 as a glycol component, (2) a long chain saturated aliphatic dibasic acid containing 12 or more carbon atoms as saturated polybasic acid component, and an acrylate or methacrylate, and (3) a long chain saturated aliphatic dibasic acid containing 6 or more carbon atoms as a saturated polybasic acid component and a long chain aliphatic dihydric alcohol containing 4 or more carbon atoms as a glycol component; and an acrylate or methacrylate.

Coated optical glass fibers and method for production thereof

A water-solubilized resin composition for forming a thermally stable polyimide polymer prepared by mixing
