主 题：Recycling thermoplastic bio-composites thermocompression process tensile properties vibration loss factor
摘 要：This manuscript deals with the effects of recycling on the static and dynamic properties of flax fibers reinforced thermoplastic *** corresponding thermoplastic used in this work is Elium ***’s the first liquid thermoplastic resin that allows the production of recycled composite parts with promising mechanical *** appeared on the resin market in *** until now,no studies were available concerning how it can be recycled and *** this study,a thermocompression recycling process was investigated and applied to Elium *** fiber-reinforced Elium composites were produced using a resin infusion process and were subjected to different thermomechanical recycling *** each material,five recycling operations were carried out on the raw material.A total of 10 different materials were investigated and tested by means of tensile and free vibration tests to evaluate the effect of recycling on their *** addition,a finite element model of the dynamic problem was developed to evaluate the loss factor and natural frequencies regarding different *** results obtained show that the failure tensile properties of Elium resin as well as flax fiber reinforced composites decrease during recycling ***,recycling induces a rise in the elastic ***,improvement in the dynamic stiffness was observed with recycling *** repeated recycling appeared to have negligible effects on the loss factor of the recycled *** results obtained from the experiment and the numerical analyses were in close agreement.
