PolymèresIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : In the construction industry, various polymeric adhesive systems are used for bonding concrete composites. The main focus is on structural safety at the interface between substrate and adhesive. To ensure a risk-adjusted selection of such systems, alternative holistic as well as empirical evaluation methods are needed, since standardized mechanical test methods are not suitable for this purpose.

Rupture (mécanique)Index. décimale : 668.3 Adhésifs et produits semblables Résumé : Existing norms and standards are only suitable to a limited extent for the verification of safety-critical bonded joints. Factors such as the quality of adhesion, various failure processes and damage effects in the boundary layer cannot yet be simultaneously recorded, combined and evaluated in the form of a single safety parameter. Fracture analysis could be used to close the gap between laboratory parameters and practical application. Note de contenu : - A holistic approach for characterizing interface bonding efficiency

Tests de sécuritéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : A new approach based on multiparametric fracture analysis evaluates the adhesive safety of double-sided adhesive tapes. As different test parameters create different test winners, it is necessary to define a well-thought-out evaluation concept that takes these inconsistencies into account. Note de contenu : - Traditional test methods with limitations
- Extensive evaluations using multiparametric fracture analysis

PorositéIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The performance of adhesives depends on a variety of influencing factors. In addition to technical parameters, economic aspects also play a major role. The influencing parameter "gap-filling efficiency" is considered in this paper from a technical-economic point of view by means of a comprehensive fracture analysis. This enables users to optimize their adhesive joint in terms of cost minimization and performance maximization. Note de contenu : - Gap bridging as a performance criterion
- Evaluation of gap-filling efficiency
- Categorization of failure modes as a function of gap
- Definition of empirical gap-filling efficiency
- Adhesive waste as a function of gap width
- Case study
- Results and discussion

EvaluationIndex. décimale : 668.3 Adhésifs et produits semblables Résumé : The selection of complex adhesive systems is still a challenging task.
