Industrie 4.0Le concept d’Industrie 4.0 correspond à une nouvelle façon d’organiser les moyens de production : l’objectif est la mise en place d’usines dites "intelligentes" ("smart factories") capables d’une plus grande adaptabilité dans la production et d’une allocation plus efficace des ressources, ouvrant ainsi la voie à une nouvelle révolution industrielle. Ses bases technologiques sont l'Internet des objets et les systèmes cyber-physiques.

Textiles et tissus -- Finition
Textiles et tissus -- IndustrieRésumé : Textile finishing has always been one of the more labor-intensive branches of industry. As well as having a direct impact on costs, this often has negative consequences in terms of quality. Seam sensors are a real milestone when it comes to overcoming these disadvantages.

Temps de cycle (production) -- RéductionIndex. décimale : 668.4 Plastiques, vinyles Résumé : Wind turbines are getting bigger and bigger, and the industry is challenged for more cost reductions and higher production efficiency. At the same time manufacturers are facing high quality criteria that come at cost. Rotor blades are typically almost a third of the cost of a turbine, and currently have a high labour content in the manufacturing process. The obvious question which come to mind is : "Can the manufacturing process be automated ?"

TempératureIndex. décimale : 668.4 Plastiques, vinyles Résumé : Regarding the necessity of lightweight construction, performance and design, composites are well established. At this moment, the joining of these composites still is often a major challenge. While suitable technologies like welding, sticking or riveting do exist, there are several drawbacks of these technologies such as damaging the fiber structure and low bonding strength. The combination of welding and sewing is a novel approach to improve the bonding of glass fibre-reinforced polypropylene and the influence of the processing parameters is not yet well understood. This study aims at analyzing the influence of parameters such as operating temperature, overlap length, needle temperature and thread material on the tensile strength of thermoplastic composites joined in the previously described hybrid approach. Furthermore, the interaction between thread and composite material is investigated by a microscopical analysis. The joint strength has been found to depend on the overlap length of the joint and the results suggest a contribution of the seam to the joint strength, especially for lower overlap lengths. Influences of the processing temperature, the thread material and needle temperature are also present, however, due to the complex interaction, no systematic conclusions could be drawn for these yet. The optical analysis confirms the findings of thermoset composites stitched before impregnation, where additional seams cause dislocations and local agglomeration of fibers. Additional investigations are necessary to determine the effect of the stitching on the joint and to further the understanding of the interaction between composite and thread material.

Tungstate de césiumIndex. décimale : 677 Textiles Résumé : Sewing and embroidery yarns containing NIR-absorbing nanopigments as safety markers based on lanthanum hexaboride and cesium tungstate nanoparticles were developed. Homogeneous dispersion of the nanopigments within polyethylene terephthalate (PET) yarns was achieved by appropriate surface modification of the particles. The nanopigments were added in masterbatches to the PET melt for fabrication of partially oriented yarns (POY). These were processed further by drawing and twisting for sewing and embroidery yarns. The safety marking can be detected by NIR-irradiation and visualized by thermal imaging. More detailed analysis of the pigment composition and fiber structure, e.g. by electron microscopy combined with EDX element analysis allows unambiguous verification of the genuineness.
