Effect of hemp fiber length on the mechanical and thermal properties of polypropylene/SEBS/hemp fiber composites

Journal of Materials Research and Technology, 2020
The control of the fiber length is proposed as a low cost and eco-friendly alternative to the expensive chemical treatments of fibers in polymer composites. Different initial lengths of hemp fibers (HF), ranging from 1 to 4 mm, were obtained using automatic milling and manual cutting.

From Material Tensions to Organizational Paradoxes: How Manufacturers Cope With the Limits of Circular Product Design

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular product design (CPD) is central to advancing the circular economy by enabling the narrowing, slowing, and closing of resource flows. Yet, its implementation remains persistently challenging for firms. Prior research has largely framed these challenges as discrete barriers, overlooking the structural contradictions embedded in CPD ...
