Modern polymer composites combine high performance with great flexibility at the cost of increased material complexity. Characterizing the basic static properties of these materials requires a wide range of mechanical tests and more complex tests are required to determine their durability under service conditions such as compression after impact (CAI) for aerospace, fatigue loading in the wind energy sector and high-speed testing for automotive crash protection. Often, the tests need to be conducted under different environmental conditions and minimizing the scatter of the results of these tests while maintaining high productivity is a major challenge.
This talk will look at some common causes of variability in mechanical test data and will outline equipment recommendations and best operating practices.
