Pressure sensitive adhesives provide beneficial properties for bi-material bonding and we here focus on influences of the loading rate. The cohesive law for a tape is measured using the J-integral method. In-situ studies of the fracture process are made. The fracture energy and cohesive law levels off below an engineering strain rate of about 2 s −1 . All the cohesive laws include two peak stresses, the first is associated with nucleation of cavities and occurs at a stress level comparable to the critical stress for cavitation in rubber. The second peak stress occurs just before final fracture when walls formed between the cavities break down. Slower rates give more time for cavities to nucleate. A similarity of the effects of loading rate and ageing is also identified.

“…For engineering use of the PSA, the long-time properties should be considered. Townsend et al [22] report creep experiments on a similar PSA (3M VHB G23F) as the one used in the present study. These show no limit stress for creep fracture.…”

“…In consideration of the actual use conditions of curved displays, a severe experimental conditions with high temperature and high humidity were constructed. This is because the creep rupture is accelerated in high temperature and high humidity environments [13][14]. Since it is very difficult to observe the inside from the outside of the chamber due to the high humidity, a heat-resistant and waterproof camera was installed inside the chamber to measure the failure time more accurately.…”

In this study, we proposed an optimal foam tape design for the assembly of curved display modules using topology optimization. We constructed the lifetime prediction model of the foam tape by verifying the correlation between the stress and the failure time with the revised power model. Two optimal designs were derived through a 2‐step topology optimization process by constructing constraints with a life prediction model. We manufactured the curved display module using the optimal design and verified its performance.

“…The creep behaviour is also of great importance in the industry since this testing allows determining the optimal range of loads to be supported by the joints for a prediction of service life [ 28 ]. Previous creep studies of PSAs have been reported in [ 29 , 30 , 31 ]. The creep response is described to depend on the applied load and working temperature; the lifetime decreases as theses variables increase.…”

Comparative Mechanical Study of Pressure Sensitive Adhesives over Aluminium Substrates for Industrial Applications

The use of adhesives for fixing low-weight elements is showing increasing interest in the industry, as it would reduce the weight of the assembly, costs, and production time. Specifically, the application of pressure-sensitive adhesives (PSAs) to join non-structural naval components to aluminium substrates has not yet been reported. In the present work, a study of the mechanical behaviour of different double-sided PSAs applied on bare aluminium alloy substrates is performed. The influence of surface roughness, surface chemical treatments, and the matrix of the adhesives is studied through different mechanical tests, such as shear, T-peel, and creep. The application of an adhesion promoter improved the mechanical behaviour. Low roughness substrates provided better performance than ground samples. Acrylic foam adhesives were subjected to creep tests, whose results were fitted to a simple mathematical model, predicting the fracture time as a function of the applied load.
