Composite Column Design/Test Lab

This research incorporates engineering design (using smart spreadsheets) into a laboratory activity focusing on columns made of composite materials. In previous work, a laboratory activity was developed supporting composite design of polymer matrix composite beams. The present work applies a similar, expanded approach to ceramic composites in the form of columns. In the lab, students simulate composite columns and use a smart spreadsheet to help optimize their design for engineering performance, including ‘specific’ properties. Parameters are discussed and evaluated before the column is made. The composite is then fabricated. Finally, the composite is tested and the experimental data (‘critical load’ for columns) is compared to predictions. Module Objectives: Upon completion of this activity, students will be able to 1. Design an appropriate composite column structure, model the composite structure, optimize the composite structure design, and subsequently predict its performance. 2. Fabricate the composite using an appropriate method and test the composite for critical parameters. 3. Critically evaluate the composite’s performance with reference to the predictions, testing methods, and appropriate literature data.
