| Résumé : |
The combination of fiber-reinforced face layers with a lightweight foam core combines high strength and stiffness with low part weight. However, when processing, it is anything but easy to combine anisotropic FRP materials with lightweight,cost-effective foams. A tailored material system now makes processing by high-pressure resin transfer molding possible at low temperatures and pressures, with short cycle times. |

- Good connection between the facing and core layers
- Evaluating the process window
- Figure : Good surface quality, pristine foam core : a cross-section through and HP-RTM part with carbon-fiber reinforcement of Airex T10.110 core and Henkel Loctite Max 2 PU resin
- Fig. 1 : Compressive strength of the foam cores Airex T10.110 and Airex TX.170 dependent on th emold temperature in the HP-RTM process
- Fig. 2 : Schematic curing behavior (DEA measurement) of Loctite Max 2 at 70°C mold temperature. The characteristically low viscosity at the start of the reaction is represented as a dotted line. Due to the freely selectable concentration of accelerator, a very curing of below 3 min can be achieved even at very low mold temperatures in the range from 60 to 70°C |
