T1 - Centrifuge technology revolutionises adhesion testing T2 - Dispersion Letters N2 - Composite materials fulfil a great variety of functions in a wide field of applications. Testing the composite properties under environmental conditions is a must for development and quality control. Common tensile strength test instruments have limitations, like single sample handling only. Present test methods for multi-layers, e.g. peel test, permit semi-quantitative ,or qualitative evaluation only. A new instrument based on analytical centrifugation is introduced, using centrifugal force as test load, permitting to determine bonding and adhesive strength of up to 8 samples simultaneously.

Therefore effective quantitative tests to determine adhesive, bonding or composite strength are of great need for R&D and QC. In this paper a new measuring principle is described which uses the centrifugal force to generate the test load. By the geometry of the whole measurement set-up, the test specimen are supported from only one side, the influence of shear forces is avoided. The possibility to test up to eight samples in one measurement under identical testing conditions allows a high sample throughput. A detailed description of the whole sample preparation procedure including pre-treatment is followed by the specification of the measuring protocol as well as result analysis. For each application area bonding strength of joints, adhesive strength of coated systems and internal strength of composite materials examples are presented.
