The strands coming out of the extruder were cooled in a water bath and pelletized (Thermo Fisher,
Stone, UK) into pieces of 2–3 mm length (Fig. 2a). All specimens
for tensile, flexural and torsion tests were molded using an Engel
e-Victory injection molding machine with a 40 tons platen force.
The process temperature was fixed at 200 C in the barrel and at
180 C at the nozzle while the mold was maintained at 45 C
(Fig. 2b).
