Plant fibers are being increasingly explored for their use in engineering polymers and composites, and many works have described their properties, especially for flax and hemp fibers. Nevertheless, the availability of plant fibers varies according to the geographical location on the planet. This study presents the first work on the mechanical prope...

The 3D warp interlock carbon fabrics, which have different structural properties, were produced and their tensile, bending, shear and formability properties were tested in our previous study. However, further analyses and modelling studies are needed to have an overall understanding of the specific and complex behaviours of the 3D warp interlock ca...

Recycling carbon-fibre-reinforced plastic (CFRP) and recovering high-cost carbon fibre (CF) is a preoccupation of scientific and industrial committees due to the environmental and economic concerns. A commercialised nonwoven mat, made of recycled carbon fibre and manufactured using carding and needle-punching technology, can promote second-life opp...

Despite the variability of Moroccan natural resources, few Moroccan natural fibers are exploited as natural textile composites. This study aims to investigate the characteristics of 3D warp interlock fabrics based on Moroccan sisal yarns. Before weaving, the characteristics of sisal yarns have been analyzed following standards. Based on these natur...

The feasibility to manufacture a 3D warp interlock preform from 1000 Tex flax roving is investigated by means of a prototype machine developed to GEMTEX laboratory. The provided flax roving has low tensile failure load because of lack of twist so it isn’t suitable for weaving. The first step was dedicated to improve the tensile properties of the ro...

Flax (Linum usitatissimum L.) has been grown since the antiquity for tis ability to provide fibres for the confection of clothes. It has also been used for the production of technical fabrics such as sails for example. In the 20th century, and particularly in Europe, the vegetal fibres such as flax were progressively replaced by synthetic fibres fr...
