Abstract
In this work a class a particle reinforced polymers have been investigated using nondestructive and destructive techniques. The velocities cl and ct
of the longitudinal and transverse waves were evaluated using ultrasounds. From
these and from the density of the material the modulus of elasticity, the shear modulus and the Poisson ratio were calculated by the appropriate relationships. The
results were compared with those obtained from destructive tensile experiments
and as well as with those derived from theoretical formulae. Also, their attenuation
coefficient α and damage parameter D were obtained and an attempt was made to
establish a relationship between strength and the effect of frequency, results obtained from dynamic experiments carried out on iron- ultrasonic attenuation in the
composite material. Finally, in order to investigate the effect of frequency, results
obtained from dynamic experiments carried out on iron-epoxy composites were
compared with those obtained from ultrasounds.
