The ZwickRoell machine, is equipped with a thermal chamber and can perform tests in the temperature range -70°C to +250°C. R-TECH can also perform liquid, humidity or temperature pre-conditioning of samples, which is an essential requirement for the aerospace sector. The new investment also incorporates the latest ZwickRoell state-of-the-art camera system for fracture toughness testing. This system enables accurate tracking of the crack propagation and allows the test sequence to be replayed post-test to ensure accurate detection of the crack front, making it the most accurate and repeatable system in the U.K. testing market. R-TECH have also invested in fixturing that will allow them to carry out V-notched rail shear testing.
Dr Geraint Harvard, R-TECH’s Composite Manager, said; “We are delighted with our new ZwickRoell machine. It has become apparent that there is a growing demand for fracture toughness testing within the composites industry, partly due to the publication of ISO 20144, the standard qualification plan for composite materials, which includes fracture toughness testing. We decided that it was important to position ourselves with the most accurate and repeatable system on the market for all fracture toughness modes required. Our continued investment in state-of-the-art equipment and the ongoing development of our team of highly qualified engineers, materials scientists, and chemists has helped us forge our reputation as one of the U.K.’s fastest growing composite testing laboratories.”
The R-TECH Materials group provides materials testing, characterisation and consultancy services on a wide range of engineering materials and applications. Operating predominantly in the aerospace, marine and automotive sectors, the Composites Department tests the mechanical, thermal and chemical properties of non-metallic materials, components and products - including plastics and fibre reinforced composites - for material approval and characterisation, quality control and research and development. R-TECH’s combination of testing, characterisation and interpretation expertise can also be applied to problem solving, such as product or processing problems or materials failure investigation. Additionally, R-TECH offers training courses on testing of composite materials in conjunction with ZwickRoell, which to date, have been very well received by over 100 participating engineers.
R-TECH is accredited by UKAS and Nadcap to perform testing to ISO and ASTM standards under controlled temperature and humidity conditions. Standard tests include lap shear, in-plane shear, climbing drum peel, shore hardness, compression of core materials and shear properties of sandwich panels. As well as a full suite of static testing, fatigue testing (in tension or in bending) at loads of up to 100 kN can also be accommodated. R-TECH’s skilled technical staff can prepare laminates and machine samples in-house as required.
R-TECH also offers its customers bespoke testing thanks to its combination of state-of-the-art biaxial extensometry with strain gauging capabilities and in-house workshop facilities, which means it can design and manufacture rigs to adapt its test equipment to clients’ requirements.
