(57) [Summary] [Object] An object of the present invention is to provide a novel light pipe having characteristics such as excellent permeability and low temperature flexibility. The present invention is a method of making a cured composite, comprising: a) i) a molten clad polymer extruded through a coextruded annular conduit to form an extruded annular cladding, and ii. ) Co-extruding a crosslinkable core mixture, which is extruded through a coextrusion type core mixture supply tube to form an extruded crosslinkable core mixture inside the extruded annular cladding, b) filling the extruded annular clad with the extruded crosslinkable core mixture; and c) curing the crosslinkable core mixture in the annular clad. |
