The future commercial prospects for adhesive tapes are very good and its application range is very broad. From every-day-use in office, packaging, maintenance, and quick repair in workshops, it ranges from handicraft work, medical purposes and cosmetics up to workmanship. The study describes a new multi-sample approach in adhesive tape testing from theoretical background, preparation of test specimen for tensile as well as shear testing, detailed measurement procedures up to analysis and result interpretation. Various types of single and double-sided pressure sensitive adhesive tapes supplied by different manufacturers were investigated and compared
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.
