Majority of polymer matrix composite materials, a marked viscoelastic behavior and faculties of dissipation of energy, it thus proves necessary to know the viscoelastic properties, as the dynamic Young modulus. In this work, we will present a new experimental technique for determining the dynamic elastic modulus at high strain rates of polymer matrix composites materials by a statistical method demanding a large number of tests. This new technique is based on the split Hopkinson pressure bar. Further, we study the effect of strain rate on dynamic elastic modulus of a woven Polyamid 6 – glass fibre reinforced.
Keywords: composite; dynamic Young modulus; Hopkinson bar; high strain rate
