Electrical strain gauges from HBM are well established all over the world. Different applications such as static material and durability testing of coupons and components rely on the high quality and the wide portfolio of over 2000 different strain gauge types.
Together with IPC, the industrial technical center for plastic and composite innovation in France, an investigation based on testing in compliance with the ISO 527-4 standard was performed to compare strain gauges embedded in the composite material (LI66-10/350) with conventional strain gauges installed on the surface of the test structure (LY21-6/350). The test was performed on glass fiber-reinforced plastic coupons.
