Abstract

© 2015 Elsevier Ltd.© 2015 Elsevier Ltd. All rights reserved. A novel manufacturing route for fully recyclable corrugated sandwich structures made from self-reinforced poly(ethylene terephthalate) SrPET composites is developed. The dynamic compression properties of the SrPET material and the out-of-plane compression properties of the sandwich core structure are investigated over a strain rate range 10 < sup > -4 < /sup > -10 < sup > 3 < /sup > s < sup > -1 < /sup > . Although the SrPET material shows limited rate dependence, the corrugated core structures show significant rate dependence mainly attributed to micro-inertial stabilisation of the core struts and increased plastic tangent stiffness of the SrPET material. The corrugated SrPET cores have similar quasi-static performance as commercial polymeric foams but the SrPET cores have superior dynamic compression properties.
