A cured composite and a process for producing the cured composite

摘要

A process for producing a cured composite, preferably a light pipe, comprising the steps of: a) concurrently and coaxially extruding: i.) a molten cladding polymer through an annular channel (2) of a coextrusion die to form an extruded tubular cladding, and ii.) a crosslinkable core mixture through a core mixture delivery tube (6) of the coextrusion die to form an extruded crosslinkable core mixture within the circumference of the extruded tubular cladding; b) filling and contacting the extruded tubular cladding with the extruded crosslinkable core mixture; and subsequently c) curing the crosslinkable core mixture within the tubular cladding.
