Implementation and optimization of the properties of a sandwich structure in biobased materials (fibres and Hemp wood) with an expanded polystyrene matrix for the building

subject

description

Due to the rapidly improving functionality of building materials, and increasingly complicated human resource management issues, the traditional cement-based building materials of the past are becoming less and less desirable.These outdated materials are being replaced by new structures of wall that better optimize choices of materials and their layouts. In this study, we propose a multi-function structure to be the unit of a typical wall (individual house), which can be produced via the use of inexpensive materials and classic manufacturing processes. To achieve this, we chose the renewable agricultural source of the hemp plant (hemp yarns and hemp shive particles), along with recycled expanded polystyrene, to manufacture a fully recyclable composite. We established a relationship between the physical-mechanical properties of the resulting composite and the parameters of the manufacturing process, particularly in the zone of high load reinforcement, we successfully manufactured a composite of 100% hemp shive particles. In addition, we have also prepared the numerical optimization phase of an alveolar sandwich structure by modeling the process and the obtained structure.
