Zwick USA (Kennesaw, GA, US) is displaying a variety of tooling, grips and fixtures designed to accommodate testing regimes. Products include interlaminar shear strength fixtures, load bearing test tools, hydraulic composite compression fixtures, 3- and 4- point flexure test kits for fiber composite materials and compression test kits for end loading. The company’s AllroundLine system is said to to perform more than 20 types of composites tests in compliance with more than 100 test standards. The TestXpert III test software supports a range of applications from shear loading of composite sandwich specimens to open-hole compression testing in accordance with ASTM, ISO and DIN standards, as well as company-specific standards. The MakroXtens extensometer can be used up to specimen break, even with high loads and brittle specimen material. With an integrated safety mechanism and rotatable knife edges, the operator and system are protected from specimen breakage. In addition, the company’s newly designed temperature chambers are fully integrated in the testing systems and can test from -70°C up to +250°C. They are compatible with ZwickRoell extension measurement systems, ensuring reliable test results for both optical and contact measurements. The chamber’s modular concept means the test setup can be adapted to suit the operator’s needs. ZwickRoell industry experts will be on hand at Booth R55 to demonstrate a 10-kN AllroundLine universal testing machine featuring body-over-wedge grips and makroXtens extensometer.
Dr. Don Adams describes six single-fiber methods for testing fiber-matrix interfacial bond strength.
Dr. Daniel O. Adams, professor of mechanical engineering and director of the Composite Mechanics Laboratory at the University of Utah, and the vice president of Wyoming Test Fixtures Inc. (Salt Lake City, UT, US), takes over for his father, Dr. Donald F. Adams, as the anchor writer in CompositesWorld magazine's revamped CW Design and Testing column. First subject? The challenges of tensile testing unidirectional composites.
