Appears in Print as: 'Composites testing machines'
Zwick Roell will highlight its latest developments in composites testing: the Amsler HIT 600F drop weight tester and the AllroundLine testing machine at CAMX 2019.
Zwick Roell (Ulm, Germany) will present flexible solutions for composites testing at CAMX 2019 to be held in Anaheim, Calif., September 23-26. Experts will be on hand to discuss the company’s latest developments in composites testing: the Amsler HIT 600F drop weight tester and the AllroundLine testing machine with grips and alignment fixtures ideal for every composites application.
The AllroundLine system for composites testing features a wide range of test fixtures that can accommodate tests under ambient and non-ambient test conditions. With the AllroundLine system, additional fixtures for three- and four-point flexure tests, inter-laminar shear strength (ILSS), and the Iosipescu V-notch shear test may be conveniently attached via slide-in inserts in place of jaws used in the pre-mounted tensile grips. The inserts facilitate rapid equipment changes, with the added advantage of maintaining the preset axial alignment of the specimen grips.
The Amsler HIT600F works in concert with the AllroundLine to perform Compression After Impact tests, which require pre-damaging of fiber-reinforced composites (CAI) to ASTM D7136, DIN EN 6038 and AITM 1.0010. Testing at low impact speeds of 2.2 m/s requires a larger drop weight; if testing at 6.6 m/s is required, acceleration is necessary. This drop weight tester caters to both situations, making it well suited to satisfy the requirements of a wide range of automotive and aerospace industry specification standards.
Common applications are:
- Puncture tests on plastics to ISO 6603-2 and ASTM D3763
- Puncture test on films to ISO 7765-2
- Pre-damaging of fiber-reinforced composites (CAI) to ASTM D7136, DIN EN 6038 and AITM 1.0010
Hand layup has a long history in aerospace composites fabrication, but it's not well suited for automotive composites manufacturing, where volumes are much higher. But the discrete placement of fiber reinforcements still has value. Research is pointing toward automated hand layup that might help this process bridge the aerospace-to-automotive divide.
The drive to boost aircraft operating efficiency continues to fuel adoption of polymer matrix composites in jet engines.
