3DEXPERIENCE Composite Fibre Modeller Technology

One of the challenge of composite manufacturing is prediction of flattened shapes of plies. Conventional tools of surface flattening are not sufficient for flattened shape prediction as it doesn’t consider behaviour of fibres on geometry. Surface flattening tools only consider surface complexity but it doesn’t consider behaviour of fibres on surface feature.

To resolve this issue, DASSAULT SYSTEMES has developed Composite Fibre Modeller technology which helps to predict the flattened shape of geometry by considering surface features and fibre behaviour. This technology allows users to predict optimum location of reference point for locating ply on tooling surface. For locating ply on tooling surface for large component needs reference of various features of tooling surface. Concept of Seed Curve and Order of Drape allows user to exactly replicate manufacturing references digitally and get accurate prediction of flattened shape of plies.



Carbon Fibre Modeller technology also helps to predict sequence of laying the ply on different surface feature on geometry. For the ply laying above core, it is difficult to predict flattened shape of ply due to solid core shape features.3DEXPERIENNCE composite fibre modeller technology allows user to consider the solid core shape features while predicting flattened shape of geometry.   

Flattened shape plies depend location of ply in stack. Composite fibre modeller technology allows users to consider thickness of plies below the ply under consideration while predicting fibre behaviour. In this prediction, user has been provided with option to define thickness of plies manually or 3DEXPERIENCE will calculate the thickness of plies automatically based on location of plies in stack.

Composite Fibre Modeller technology helps to animate draping simulation process. This helps visualise effect of different geometrical features of draping simulation. This helps define location of dart accurately. Composite Fibre Modeller provides nine different algorithms which helps to process very complex geometries and complex material behaviour, predicting accurate flattened shape of plies, reducing waste of time and material on shop floor.

Another advantage of this technology is its compatibility with finite element analysis. Draping simulation results can be read by finite element analysis tools within 3DEXPERIENCE.This helps to compute the strength of composite geometry in as build scenario giving more realistic prediction.

Integration of this technology with 3DEXPERIENCE helps Composite Design and manufacturing team to predict fibre behaviour accurately and help to reduce efforts and raw material required on shop floor.
