Optimising industrial hemp fibre for composites

Properties of Hemp Fibre Reinforced Concrete Composites

This research is concerned with the mechanical and physical properties of hemp fibre reinforced concrete (HFRC). An experimental program was developed based on the statistical method of fractional factors design. The variables for the experimental study were: 1) mixing method; 2) fibre content by weight; 3) aggregate size; and 4) fibre length. Their effects on the compressive and flexural perfo...

Development of Natural Hemp Fibre Sheet Mould Composites (NF- SMC)

The use of natural fibres as reinforcement in polymer composites has generated much interest in recent years due to environmental legislation and improvements on natural fibre performance and process-abilities. This research investigated the use of natural hemp fibre as reinforcement for the possibility of producing fibre reinforced Sheet Moulding Compounds (SMC) as an alternative to glass fibr...

hemp, and flax composites

This study characterizes the acoustical behavior of natural fiber composites. Regenerated cellulose fibers (Lyocell), hemp fibers, and flax fibers were embedded in an epoxy-matrix. These unidirectional composites were tested for their logarithmic damping decrement, the resonance frequency, the ultrasound velocity, the dynamic and static modulus of elasticity, and bending strength and density. G...

Effect of water absorption on the mechanical properties of hemp fibre reinforced unsaturated polyester composites

Hemp fibre reinforced unsaturated polyester composites (HFRUPE) were subjected to water immersion tests in order to study the effects of water absorption on the mechanical properties. HFRUPE composites specimens containing 0, 0.10, 0.15, 0.21 and 0.26 fibre volume fraction were prepared. Water absorption tests were conducted by immersing specimens in a de-ionised water bath at 25 C and 100 C fo...
