This paper investigates the mechanical properties in terms of tensile, flexural, compression, and Charpy impact strength of a new lightweight grid structure in bio-composite material based on woven hemp fabric and bio-epoxy resin. The main intent was the manufacturing of bio-composite with high specific mechanical properties produced through a new process that can be easily implemented in industrial production, and that can produce low density composites in a continuous way with a good level of repeatability. This was done by using two hemp fabric types, that mainly differ in the fabric mesh size. Several hemp/bio-epoxy resin grid structures with different density (in the range of 0.47–0.80 g/cm3) and thickness (in the range of 4.3–12.3 mm) were obtained and their properties were widely investigated. The results showed interesting mechanical properties possessed by the bio-composites so manufactured, highlighting their possible use as core for sandwich composite structures.

Abstract

This paper investigates the mechanical properties in terms of tensile, flexural, compression, and Charpy impact strength of a new lightweight grid structure in bio-composite material based on woven hemp fabric and bio-epoxy resin. The main intent was the manufacturing of bio-composite with high specific mechanical properties produced through a new process that can be easily implemented in industrial production, and that can produce low density composites in a continuous way with a good level of repeatability. This was done by using two hemp fabric types, that mainly differ in the fabric mesh size. Several hemp/bio-epoxy resin grid structures with different density (in the range of 0.47–0.80 g/cm3) and thickness (in the range of 4.3–12.3 mm) were obtained and their properties were widely investigated. The results showed interesting mechanical properties possessed by the bio-composites so manufactured, highlighting their possible use as core for sandwich composite structures.
