Overview

LUSAS HPM software can accurately predict the distortion of laminated composite parts during manufacture and provide reverse engineered surfaces to create "right first time" tooling. As a result considerable savings can be made in time to market. Manufacturing time and costs are less, assembly stresses are lowered, and the time-consuming fitting of any shims are eliminated.


Background to Composites Manufacture

During the cure of a composite part residual stresses develop resulting in distortion of the component from its moulded shape. This causes potential difficulties in its use in product assembly. In aircraft airframe applications it is estimated that a high percentage of the costs associated with composite parts occur during the assembly process. This is mainly due to the distortion of individual components and the time associated with the rework and shimming processes required to accommodate these distortions. As an example, an aircraft assembly may require a significant amount of shimming to correct errors due to component distortion. Historically trial and error tooling changes have been carried out in order to try to achieve the desired post-cure part shape but a more accurate and less ‘hit and miss’ method needed to be found. As a result, LUSAS HPM software was developed.
