Composite Column Design/Test Lab
Effective engineered composite design activities require predictive and quantitative methodology. This research incorporates engineering design, using smart spreadsheets, into a laboratory activity focusing on columns made of composite materials.
In a previous work1, a laboratory activity was developed supporting composite design of polymer matrix composite beams. The present work applies a similar approach expanded 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.
The National Educator’s Workshop requires certain information be provided in the manuscript. This information includes ‘Key Words’, ‘Target Grade Level(s)’, ‘Prerequisite Knowledge’, ‘Objectives’, and ‘Equipment and Supplies Needed’ are shown below. A traditional ‘Introduction’ appears subsequently.
Key Words: Composites, Column Design, Spreadsheet Optimization
Target Grade Level(s): This activity is oriented to Grades 13-16 (undergraduate college).
Mode of Presentation (lab, demo, in-class activity, etc.): This activity includes in-class, demo and lab aspects.
Prerequisite Knowledge: Students should be able to 1. use spreadsheets, 2. have basic knowledge of both structures (beam bending and columns) composites and composites structures, and 3. have the logic and math skills necessary to plan and quantify the composite design and optimization process.
• Students should be able to design an appropriate composite column structure, model the composite structure, optimize the composite structure design, and subsequently predict its performance.
