Uncertainty in manufacturing of lightweight products in composite laminate—part 2: experimental validation
- 29 Downloads
One of the obstacles for composite applications is the geometry assurance. Traditional dimension control operations for composites are mainly based on trial-and-error approaches, which cannot be directly and effectively employed in real-world part design and tooling development. With the increasing requirement for composite products to be affordable, net-shaped, assembly efficient, and effective dimension control is highly desirable. Currently, composite components cannot be processed to the tolerance level required for an assembly because of the lack of dimension control. Better dimensional control can improve assembly, reduce extra processing steps, and make parts interchangeable for rapid repair and retrofit. Variation analysis represents the best way to solve these assembly problems in order to ensure higher quality and lower costs, but few studies have focused on this issue. Therefore, the aim of this work is to experimentally solve an assembly constituted by parts in composite material and joined by adhesive in order to use these results to validate a numerical tool for variation analysis of compliant part.
