The paper addresses the “State-of-the-Art in Multiple-Sample Evaluation of Adhesive and Bonding Strength” and the following points are discussed in more detail:
1. Motivation (coatings, varnishes, tapes, laminates, CFRP, adhesive-bonded joints)
2. Conventional single-sample testing (evaluation of adhesive and bonding strength; failure pattern)
3. Multiple-sample handling (MSH), bonding (MSB), and testing: centrifugal adhesion testing (CAT) (multiple-sample approach, tensile test within a centrifuge)
4. Application examples of CAT-Technology™ (laminates, optical coatings, CFRP joints)
Finally, a summary is given regarding status quo and benefits of CAT-technology under tensile stress conditions whereas examples of testing in a centrifuge under compressive stress conditions are mentioned in the outlook.
Der Vortrag widmet sich der „CAT-TECHNOLOGIE ZUR BESTIMMUNG DER HAFTFESTIGKEIT DÜNNER SCHICHTEN“ und beschreibt die Punkte „Motivation –CAT-Technologie“ (CAT: Centrifugal Adhesion Testing) und die „Haftfestigkeit von Schichten“, (Ag-Schichten auf N-BK7 Glas, Cr- und Al-Schichten auf Borofloat 33 Glas, Au-Schichten auf N-BK7 Glas und SiO2-Schichten auf CR39 Polymer) im Einzelnen.
