Abstract:

The effects of deformation of the reinforcement during manufacture on the elastic properties of textile composite components have been investigated. Fibre reorientation and changes in the fibre volume fraction are considered as the dominant mechanisms affecting mechanical properties. A model is presented for the prediction of the component's elastic performance. Fibre orientations may be predicted or measured; methods for each approach are outlined briefly. The component geometry is described using a finite element mesh, and for every element fibre orientations are used to determine fibre volume fraction. Elastic properties are calculated for each element and an input deck for structural analysis using the Abaqus/Standard™ finite element code is produced. Experimental data for tensile tests conducted on angle ply laminate specimens at a range of ply angles are presented; predictions show good agreement with these data. Predicted results for a jet engine nose cone subjected to a pinch loading also show good agreement with experimental results. The effect of compaction on multilayered laminates made from dissimilar reinforcements is also discussed.
