Abstract

In recent years, a remarkable increase in the use of polymers as matrices for wood plastic composites (WPC) has been detected. Typical matrices are petroleum-based materials and the lignocellulosic component is usually derived from the wood industry. The use of environmentally friendly polymer matrices is a great challenge to give high environmentally efficient materials. Polylactic acid (PLA) is a bio-based polymer which can be suitable for WPCs as it can provide full biodegradability together with the lignocellulosic component. Although PLA offers new attracting uses in engineering applications, it is characterized by high fragility, so that, one of the challenges related to PLA use is to improve its intrinsic low energy absorption capability. On the other hand, the food industry generates huge amounts of lignocellulosic wastes that can be suitable as active fillers in WPCs as many of these lignocellulosic wastes possess antioxidant properties and can contribute to stabilize polymer formulations. Hazelnut industry generates large volumes of shell wastes which are characterized by exceptional antioxidant properties. These wastes could be an attracting solution to obtain fully biodegradable WPCs with balanced mechanical performance. The aim of this work is to evaluate the influence of the hazelnut shell powder content on mechanical properties of WPCs with polylactic acid (PLA) as well as the particle-matrix interactions.
