“…The calculated value for elementary fibre is close to what is reported in the literature for flax elementary fibre, 1.14 [10] evaluated at 20-98% RH. In the case of flax technical fibres, the calculated βr is far from the value estimated in literature, which is 1.06 [15] and 0.63 [31] evaluated at 8-97% RH and 20-73% RH, respectively. Possible reasons for the differences in the measured βr of flax technical fibre could be the fibre materials and method used in the swelling measurement.…”

“…The swelling or shrinking of wood and cellulosic fibres such as flax is normally quantified by the swelling/ shrinkage coefficient (β) which can be defined as the strain induced by a variation of 1% moisture content (MC) [5]. Some of the values reported for flax elementary and technical fibres are 1.14 [10] and 1.06 [15], respectively.…”

“…Natural Fibre Reinforced Polymer Composites (NFPC) are in demand for semi structural applications due to their relatively low density, high specific strength and low environmental impact. 1 Increasing fibre percentage tend to have a positive impact on Young’s modulus and strength properties but deformability and impact resistance tend to decline, however for engineering applications toughness is a very important property. 2 During the service life of the component, materials undergo different kinds of loadings and the material having low toughness can experience sudden failure.…”

Reinforcing thermoplastic polymers with natural fibres tends to improve tensile and flexural strength but adversely affect elongation and impact strength. This limits the application of such composites where toughness is a major criterion. In the present work, bamboo fibre reinforced polypropylene (PP) composites were prepared with bamboo fibre content varying from 30% to 50% with improved impact resistance. Homopolymer and copolymer PP were used as the matrix polymer and an elastomer was used (10% by wt.) as an additive in the formulation. Copolymer based composites exhibited superior elongation and impact strength as compared to homopolymer based composites. The adverse impact of elastomer on tensile and flexural strength was more pronounced in homopolymer based composites. The study suggested that the properties of the bamboo composites can be tailored to suit different applications by varying reinforcement and elastomer percentage.

“…The effect of hygro-thermal environment on post-buckling behaviour of laminated plates based on Reddy's higher order plate theory (HOPT) has been studied by Shen (2001). Abida et al (2020) have extensively examined the hygro-mechanical combined effect on correlation coefficient analysis of flax yarns and flax/epoxy composites. Abdelmalek et al (2017) observed the hygrothermal effects of composite plate free vibration behaviour using node n-order shear deformation theory.…”
