This paper presents the outcomes from an extensive investigation on the structure and geometry of single hemp fibres, as well as configurations and related tensile strength (TS) of hemp fibres, with the aid of field emission scanning and optical microscopy. The results showed that 1) the TS increased with the decrease of the diameter of individual test pieces, due possibly to the stacks of multiple single fibres within the test pieces; 2) shear failure between single fibres in a test pieces… 
Tensile properties of chemically treated hemp fibres as reinforcement for composites
Natural fibres, unlike synthetic fibres fabricated in-house, grow naturally. Their geometrical and physical properties are highly affected by environmental issues such as climate change. For
Investigation of the possible origins of the differences in mechanical properties of hemp and flax fibres: A numerical study based on sensitivity analysis
Abstract Despite the great similarities in the physical and chemical properties of flax and primary hemp fibres, literature generally reports differences in their average tensile properties. This
Diameter dependence of the apparent tensile modulus of hemp fibres: A morphological, structural or ultrastructural effect?
Abstract The aim of this paper is to investigate the origin of the diameter-dependence of Young’s modulus in hemp fibres. In view of the considerable experimental difficulties encountered when
Modeling the tensile strength of hemp fibers and short hemp fiber reinforced composites
Ecological and economical considerations foster replacement of man-made fibers by natural renewable fibers in various industrial applications. Proper description of the scale effect of fiber strength
Analysis of the hemp fiber mechanical properties and their scattering (Fedora 17)
Understanding the mechanical behavior of plant fibers is a key to their development in composite reinforcement. The aim of this work is to better understand the low and scattered mechanical
Effect of Strain Rate on Fracture Toughness of Hemp Fiber Composites
Many fiber reinforced polymer composites are finding increasing use as primary load-bearing structures and also in a wide range of high technology engineering applications. For upgrading the
Estimation of the Effects of the Cross-Head Speed and Temperature on the Mechanical Strength of Kenaf Bast Fibers Using Weibull and Monte-Carlo Statistics
Methods used by different researchers to evaluate plant fibers’ (PFs) mechanical performance, show great variance in results. In this work, 320 single kenaf fibers of gage lengths 10 and 20 mm were
Effect of Chemical Composition, Anatomy and Cell Wall Structure on Tensile Properties of Bamboo Fiber
Ligno-cellulosic fiber is an effective reinforcement as an alternative for man-made fiber in composite, while keeping the weight of the composite lower. In this paper, the assessment of bamboo fiber
Damage Kinetics at the Sub-micrometric Scale in Bast Fibers Using Finite Element Simulation and High-Resolution X-Ray Micro-Tomography
The predictive analysis demonstrates the relevance of using embedded microstructure simulations to reveal the extent of stress localization and predict the failure properties in bast fibers for innovative composite manufacturing for instance.
Interfacial properties and structural performance of resin-coated natural fibre rebars within cementitious matrices
Abstract This paper investigates the interface and behaviour of continuous natural fibre rebar reinforced cementitious composites. Various resins were used to coat sisal fibres which were then used


Characteristic and Performance of Elementary Hemp Fibre
This paper presents systematic and improved methodologies to characterize the surface and fracture of elementary hemp fibres by Field Emission Scanning Microscope (FE-SEM), determine the Microfibril
In situ ESEM study of the deformation of elementary flax fibres
The deformation behaviour of single elementary flax fibres was investigated in an ESEM, using a modified loop test, and the secondary cell wall was found to split relatively easily along the length direction, indicating that the lateral strength of the fibre is lower than its tensile strength.
Tensile deformation of a flax fiber
Abstract In this paper we investigate the tensile properties of a natural composite material: the flax fiber. The beginning of the stress-strain curve of a flax fiber upon tensile loading appears
An improved method for single fiber tensile test of natural fibers
An improved Single Fiber Tensile Test (SFTT) for the natural fibers was depicted. Natural fibers have irregular shape, and are not uniform along the fiber length and also from one fiber to another.
