THE FIBERS ARE ALIGNED PARALLEL TO EACH OTHER, BUNDLED TOGETHER IN AN EXTRUSION CANISTER, AND COEXTRUDED TO FORM A MONOLITHIC STRUCTURE IN WHICH THE CLADDING FORMS A CONTINUOUS, HONEYCOMB-TYPE MATRIX UNIFORMLY EXTRUSION-BONDED TO THE FIBERS AND SEPARATING THEM FROM EACH OTHER. THE FIBERS ARE CHOSEN FOR THEIR HIGH STRENGTH WHILE THE PROTECTIVE CLADDING IS CHOSEN FOR ITS ABILITY TO PROTECT THE FIBERS FROM THEIR ENVIRONMENT OR FROM EACH OTHER.
