- Abstract
- A reliable tensile test technique for PDP’s barrier rib materials was introduced. A tensile specimen
was prepared by punching out of green sheet, curing the specimen in a high temperature furnace,
attaching sand paper tabs on each grip ends, and then attaching two strain gages for the strain
monitoring and specimen alignment. Preliminary tensile tests were successfully done with the
specimens made from ZnO-based lead-free green sheet. The specimens cured at 3 different
maximum curing temperatures were tested to demonstrate the applicability of the test method.
The Young’s modulus was 88 ± 4 GPa regardless of the maximum curing temperature. The
ultimate tensile strength was decreased with increasing the temperature. The tensile test method
proposed in this study was proven to be reliable, useful and easy to estimate the bulk mechanical
properties of barrier rib materials.
