Résumé : |
In the manufacturing of RTM structural components, semi-finished textiles can be locally reinforced at different angles using a special weaving procedure. This allows the mechanical properties to be improved in highly stressed areas. |

- Glass-fiber-reinforced headlamp bowl with local carbon fiber reinforcement. It was possible to enhance the mechanical properties according to the load orientation through the multi-axial integration of carbon fibers into the basic glass fabric
- Multi-axial fabric reinforcement
- The challenge of reshaping
- FIGURES : 1. Reinforcing fabric made of glass fibers without and with multi-axial reinforcement : a) bi-axial base fabric ; b) tri-axially reinforced fabric, angle + 21° ; tetra-axially reinforced fabric, angle ± 21° - 2. Schematic diagram of the ORW concept - 3. Comparison of the tensile and bending properties of composites without and with multi-axial reinforcement at 41°. The properties in multi-axial direction could be further enhanced by increasing the amount of fibers per centimeter during the weaving process - 3. Comparison of the tensile and bending properties of composites with multi-axial reinforcement at 41° and 21°. One reason for the improvement of the mechanical properties is presumably the smaller ondulation of the fibers at 21° - 4. Comparison of the tensile and bending properties of composites with multi-axial reinforcement at 41° and 21°. One reason for the improvement of the mechanical properties is presumably the smaller ondulation of the fibers, at 21° - 5. Steps for the further processing of a fabric, which was reinforced multi-axially using ORW, to produce a finished fiber composite component : two-dimensional pre-cut fibers and fiber preform, infiltrated RTM component |
