This study focuses on the development and mechanical testing of a quasi-unidirectional woven hemp fabric for composite applications. The fabric is designed to combine the advantages of easy handling, impregnability by resin and fiber alignment. In this sense, low twisted rovings, low crimping characteristics and a high roving density in the main di...

Natural fibers are used to produce environmental-friendly composites with good specific mechanical and acoustical properties. Production of woven reinforcement from natural fibers is challenging because of the distinct length of the fibers. A lot of parameters at fiber extraction, spinning and weaving stages have an impact on the composite produced...

The objective of this study is to develop hybrid hemp/thermoplastic roving adapted for composite manufacture. The hybrid roving has to be enough resistant to sustain the tension and abrasion stresses caused by the textile production processes. For this purpose, a multifilament of polyamide 12 is wrapped around a hemp roving. This wrapped roving is...

Recent developments in the field of bio-based composite materials are mainly focused on the use of unidirectional reinforcements. The production of woven fabrics and required yarns or rovings is still complex for composite applications due to the finite length of plant fibers and to the high number of process parameters which can be tuned. This stu...

Les fibres naturelles sont de plus en plus utilisées en remplacement des fibres synthétiques dans la réalisation de préformes pour matériaux composites. Ces fibres naturelles, utilisées notamment pour leur aspect respectueux de l’environnement, sont majoritairement utilisées avec des résines thermodurcissables, qui sont difficilement recyclables. L...

Reinforcement permeability represents crucial parameters in the manufacturing of fiber reinforced composites by liquid composite molding processes (LCM) [1]. Evaluation of fabric permeability is usually challenging and it requires several flow experiments. Indeed, permeability usually presents different values due to the anisotropic nature of texti...

Les fibres de chanvre sont de plus en plus utilisées pour le renfort de matériaux composites biosourcés, du fait de leur faible densité, de leur faible coût de production et de leurs bonnes propriétés. Les renforts en fibres de chanvre actuellement disponibles sur le marché sont sous forme de nontissés ou d’unidirectionnels. Les quelques préformes...

Cette étude décrit à la fois la faisabilité du tissage 3D interlock chaine à base de mèches de lin et la caractérisation multi-échelle de ces renforts secs pour matériaux composites. Le tissage 3D interlock chaine permet de réaliser des structures épaisses, plus résistantes aux délaminages que les empilements de tissus 2D. Les propriétés mécaniques...

The three-dimensional weaving process enables to produce near-net shaped complex preforms used as reinforcement of composite materials. However, the lack of knowledge on the mechanical behaviour of these three-dimensional woven structures may restrict their use for composite material. To fill this gap, we have tempted to highlight their specific me...

Natural fibres are used as an alternative to man-made fibres in fibre reinforced composite materials in a variety of applications due to their good specific strength and stiffness properties and limited environmental impact. However, contrary to man-made fibres, used in the form of continuous filaments, natural fibres are extracted from plants in w...

3D warp interlock fabrics have been used both in composite materials as fibrous reinforcement as well as in protective solutions against impact mainly due to their improved capacity to absorb energy by higher intra-ply resistance to delamination. However, depending on the type of architecture used, the binding warp yarns may provide different types...
