Investigations on physical-mechanical properties of effective thermal insulation materials from fibrous hemp

Abstract

Depletion of fossil fuels resources and large amounts of pollutants emitted to the atmosphere enforce searching for alternative renewable resources. One of these resources is fibred hemps. The main components obtainable during the processing of fibred hemp biomass – fibres and shives, they are characterised by low density and porous structure; thereby, they are suitable for the production of thermal insulating composites. The research is based on investigation of two types composites produced from hemp fibres and hemp shives as well as biologically divisible binders. The investigation covers the impact of different amounts of binders and hydrophobizers on physical-mechanical properties.
