6. Conclusions
This paper addresses the characterization of the mechanical
response of short-fiber reinforced thermoplastic tubes. The tubes
are manufactured by helical winding of a composite made of highdensity
polyethylene (HDPE) with short glass-fibers as reinforcement.
The mechanical behavior of the composite lamina was
characterized by means of monotonic and loading/unloading tensile
tests at different deformation rates. The tests were performed
on specimens extracted in the axial and circumferential directions
of the tube
