Palmiers et constituantsIndex. décimale : 668.4 Plastiques, vinyles Résumé : Fabrication methods combining a laminating process, hand lay-up and compression moulding were developed and utilised to manufacture bio-composite specimens from naturally-sourced fibres such as palm and coir. The mechanical properties of these bio-composite materials were analysed and evaluated through impact, tensile, compression and bending tests. However, the mechanical performance of the bio-composites was found to be inferior to that of conventional glass fibre composites. The hybridization of natural fibres with glass fibre composites provides a significant increase in specific strength and specific modulus.

kénaf et constituantsLe Kenaf (Hibiscus Cannabinus L. et Hibiscus Sabdarifa L.), aussi appelé chanvre de Deccan, est une plante annuelle de la famille des Malvaceae.
Le kenaf est apparenté au jute. Ces tiges épineuses d'1 à 2 cm de diamètre sont souvent, mais pas toujours ramifiée. Les feuilles de 10 à 15 cm de longueur sont de forme variable, celles de la base sont lobées et celles du sommet lancéolées. Les fleurs de 8 à 15 cm de diamètre sont blanches, jaunes ou pourpres. Le fruit est un capsule contenant plusieurs graines.

Traction (mécanique)Index. décimale : 620.19 Autres matériaux Résumé : In recent years, an increased interest has risen in developing natural fiber reinforced bio-composite for non-structural applications. The availability of natural fibers, low cost, and useful properties such as specific strength, stiffness and, environmental-friendly degradability make bio-composite a viable alternative to synthetic composites. Therefore, there is a need to develop a bio-composite with predictable engineering properties. In order to obtain a composite with predictable engineering properties, behavior of fiber matrix, and their interface should be understood in order to select appropriate processing parameters like temperature, pressure, time etc. Studies done by various authors on properties and behavior of kenaf fibers and its fabrication methods are presented. Due to the nature of bio-fibers, a wide variety of properties are reported. The morphological structure using SEM (Scanning Electron Microscopy) is shown indicating the difficulty in obtaining consistent results and testing of the tensile behavior of kenaf fibers is reported, exhibiting linear and brittle behavior.

Résistance au cisaillementIndex. décimale : 668.4 Plastiques, vinyles Résumé : Stress concentration is an unavoidable phenomenon during the fabrication of composite structures. This research focuses on reducing stress concentration. Circular holes made on the composite structural member induce stress-concentrated regions. These stress-concentrated regions around the circular hole (considered as a weak section) were strengthened by adding synthetic fibre (local hybridization) in the form of fibre stitches (locked loop stitch). Through conducting a single fibre pull-out test, the present study analysed the impact of incorporating synthetic fibres in stitch form and the enhancement of Interfacial Shear Strength (IFSS). The load acting on the broken warp fibres is distributed to the broken weft fibres when the number of concentric stitches increases. The increment of concentric stitches resulted in the increase of IFSS due to localized hybridization. The tensile test results also show a significant improvement with 110 Nmm axial fastening force, from 6.749 MPa (for the natural fibre composite) to 76.91 MPa (for locally hybridized with eight concentric stitches). A simple bolted lap joint with local hybridization around the hole has been evaluated for different clamp-up forces. The best combinations of the clamp-up force and the extent of hybridization have been identified. SEM images illustrate the reduced voids and the reduced fibre pull-out due to the local hybridization around delamination-prone areas. Note de contenu : - Literature survey

Vis barrièreIndex. décimale : 668.4 Plastiques, vinyles Résumé : The difficulty of feeding cellulose fibers together with the polymer into the melt processing equipment is a serious disadvantage for the production of cellulose-containing composites on a large scale. In the present work, a continuous method of feeding cellulose in the form of a tissue into a twin-screw extruder through an opening downstream of the extruder cylinder was studied. With this method, composites with different fiber contents were obtained. The tissues used were one made mainly of softwood fibers and another mainly of hardwood fibers. In order to better understand how to improve the fiber dispersion by melt mixing, a second extrusion was performed with a single screw extruder with a barrier-flighted screw and also with the twin-screw used to compound the tissue with the polymer. The compounds produced were then injection molded into test bars. The test bars containing the softwood tissue exhibited some fiber aggregates also after a second extrusion, whereas no fiber aggregates were observed in samples made with the tissue containing hardwood fibers and two passes through the twin screw. The fiber length was in general reduced by each melt processing stage and the shortest fiber length was observed after two extrusions with the twin-screw and injection molding. The tensile modulus increased with increasing fiber content. A higher stiffness was obtained with more softwood fibers in the tissue whereas more hardwood fibers gave a higher tensile strength and greater elongation at break.

Réaction de couplageIndex. décimale : 668.4 Plastiques, vinyles Résumé : Before injection molding, wood polymer composites (WPC) normally have to be dried to achieve optimal quality of the injected parts as well as to avoid corrosion of the mold. Based on a literature study, there are currently no published investigations dealing with the dependency of WPC properties on the initial moisture content of the compound's pellets. Further, it is known that water and wood in combination with high temperatures can lead to corrosion of steel parts, but a systematic analysis of the impact of WPC injection molding on tool corrosion has not been found in the literature. For the present study, a compound with 68 wt% (weight percent) polypropylene, 30 wt% wood flour and 2 wt% coupling agent was produced and tested in injection molding trials. Specimens according to ISO 527-2 were produced from WPC with defined moisture contents, respectively. Compound moisture, already at very low contents, had significant negative effects on the tested mechanical properties, namely tensile modulus and strength, unnotched and notched Charpy impact strength and heat deflection temperature. Corrosion trials were performed for different tool steel qualities. The severity of corrosion correlates with the amount of chromium (Cr) in the alloys tested.
