With increasing use and understanding come ever higher demands and expectations on what can be achieved with design optimisation. Working with teams to understand the requirements of Formula One composite design, UK-based design and engineering company, GRM, have developed an efficient laminate optimisation software tool which has become the standard for Formula One. Linking into their existing laminate design processes, teams are finding new ways not just to save mass, but to maximise performance within the rules. One such example is the behaviour of the front wing which, whilst ideally deflecting to reduce drag at high speeds, must meet the governing body’s tough requirements for bending stiffness. By applying GRM’s optimisation techniques, based upon the FEA tool Genesis, the ply patterns and orientations are tailored to meet the regulatory loads whilst allowing increased bending and twist under high speed aerodynamic loads. The figure below demonstrates how, under the same loading, the optimised wing (green) induces significantly more rear edge deflection compared to a more conventional laminate (red), reducing drag and saving precious tenths over a lap. All this is achieved whilst visibly reducing the bending of the front part of the wing.
