Evaluating Interior Part Strength: Seat Fabric Tensile Testing

Automotive seat fabrics are usually composites, consisting of a high-quality synthetic leather exterior and an elastic sponge-like foam interior.As a result, tensile tests are performed for each production lot, with strict quality control in lot increments. However, while seat fabrics are soft, pliant materials, their shape is often warped, making it a difficult material for automated testing. To improve test efficiency, testers are used that stretch three samples simultaneously. In addition to seat fabrics, this type of multi-sample tester is also frequently used for rubber products.

• AG-10 kNX
•Load Cell 1kN 3 pcs
•Pneumatic flag grips (PFG) 1kN 3pcs
•Foot valve unit

This is an example of data acquisition via special testing software.
During testing a 3-line curve is displayed in real time, and when the test is complete, the combined results from each sample are automatically displayed together with the statistical results.
