Matrix Applied Computing
The New Zealand company Matrix Applied Computing has successfully used Patran Laminate Modeler to generate flat patterns for strips of material quickly and effectively from a CAD model of a racing yacht. For racing yachts where stiffness and mass are of paramount importance, the draping simulation provides accurate material directions and hence more reliable stiffness optimization. The use of MSC Laminate Modeler is now an integral part of the company's design offerings.
Challenge:High-performance yachts are often made from expensive carbon-fiber reinforced pre-preg materials. These are typically supplied in rolls and are laid on male or female molds to form the skins of the boat hull. Because hulls are typically of compound curvature, the strips will overlap when laid over the hull unless they are trimmed. This trimming is typically done using preliminary paper patterns which are themselves draped over the hull and cut to size. This process is difficult and expensive, and introduces errors.
Solution:A New Zealand company, Matrix Applied Computing, has successfully used MSC Patran Laminate Modeler to generate these patterns quickly and effectively from a CAD model. The specifications called for accuracies on the order of +/-1mm. With advice from experts at MSC Software, Matrix developed flat patterns for strips of material to be draped on a 16m hull section using MSC Patran Laminate Modeler.
Benefits:The draping simulation provided accurate material directions and hence more reliable stiffness optimization.
