Bio-based products are paving a promising path towards greener future and helping win the fight against climate change global warming mainly caused by fossil fuel consumption. This paper aims at highlighting acoustic, thermal, mechanical properties of hemp-based biocomposite materials. Change in sound absorption as result hemp fibers particle reinforcement discussed this paper. The thermal char...

This research is aimed at seeing how different stacking sequences and chemical treatments impact the mechanical characteristics of ramie–hemp composites. Hand-lay-up procedures were used to create a blend woven ramie hemp fibers. The was treated with diluted 6% sodium hydroxide (NaOH) solution compare properties preserved unpreserved hybrid According findings, tensile composites are better in t...

Hemp is finding a strong renewal of interest in the production fine fibers for garment textiles. This resource long-line would come as complement to highly demanded flax fibers, whose large north-west Europe cannot be extended. In Normandy, where complete industrial value chain exists flax, it intended adapt hemp, and this was demonstrated from field scutched with chain. region, early harvestin...

Results of a systematic study on the Ag, Cd and Pb ions sorption characteristics and kinetic properties of an unconventional material produced by introducing sulphydryl functional groups into natural hemp fibers are presented and discussed. The equilibrium data are analyzed using the Langmuir and Freundlich isotherm models. The monolayer sorption capacity of modified hemp is 10.75, 14.05 and 23...

Novel, low density structures which combine biologically-based fibers with clay aerogels are produced in an environmentally benign manner using water as solvent, and no additional processing chemicals. Three different reinforcing fibers, silk, soy silk, and hemp, are evaluated in combination with poly(vinyl alcohol) matrix polymer combined with montmorillonite clay. The mechanical properties of...

Cr (III) removal from aqueous solutions by sorption in a fixed bed column filled with alizarin S impregnated hemp fibers has been studied. The effect of the initial metal ion concentration on the Cr (III) sorption process was investigated and the experimental breakthrough curves were obtained. The breakthrough time and saturation time decreased from 110 min to 80 min and from 300 min to 160 min...

Textile materials made from natural fibers have played an important role in the life of human beings from time immemorial and still are widely used in the modern textiles industry for their unique properties as high quality tex tile materials. Due to the variation in staple length, the natural fibers with short staple length can’t be used to spin yarns. Consequently, natural fibers such as wool...

This work presents an improved single fiber pull-out test for fiber/matrix interface characterization. This test has been used to study the Inter-Facial Shear Strength ‘IFSS’ of hemp fibers reinforced polypropylene (PP). For this aim, the fiber diameter has been carefully measured using a tomography inspired method. The fiber section contour can then be approximated by a circle or a polygon. Th...

“Hemp” refers primarily to Cannabis sativa L. (Cannabaceae), although the term has been applied to dozens of species representing at least 22 genera, often prominent fiber crops. For examples, Manila hemp (abaca) is Musa textilis Née, sisal hemp is Agave sisalina Perrine, and sunn hemp is Crotolaria juncea L. Especially confusing is the phrase “Indian hemp,” which has been used both for narcoti...
