ABSTRACT = {The properties of polyethylene terephthalate (PET) reinforced with 1, 5, 10, 15 and 20% (w/w) alkaline-treated 
hemp fi bers were investigated following a series of processing stages. The fi ber concentration signifi cantly 
impacts the compounding process, yielding thermostable composites below 300°C. Their elastic moduli varied 
logarithmically with fi ber concentration, and were increased by up to 20% with respect to the nonreinforced 
formulation. Such reinforcement was, however, followed by a drastic decrease in the elongation at break, from 
more than 20 mm for the unreinforced PET to as low as 2.5 mm. Other properties showed closer observations 
to the variations of the elastic moduli. An appreciably good fi ber-matrix interface was also observed; however 
the actual processing method could not take advantage of the fi ber’s length. This work has a major impact in 
the development of composite biomaterials, as it extends their application range to the subexploited area of 
high-melting thermoplastic matrices reinforced with natural fibers.},
