Effects of manufacturing parameters on mechanical interface properties of thin wood veneer laminates Int. J. Adhes. Adhes. (IF 3.4) Pub Date : 2023-12-30 Sergio Orellana, Kenny Hadi, Darren Narain, Matt Jennings, Mahbube Subhani, Johannes Reiner
This study explores fast manufacturing techniques for thin wood laminates made from European beech veneers and 1-component polyurethane adhesive. Manufacturing factors such as pressure and pressing time are investigated following well-established standards developed for fibre-reinforced materials (ASTM D5528 and ASTM D7905). Mode I and Mode II interlaminar fracture properties are calculated to quantify

The effect of neat and modified montmorillonite on thermal properties of silicone pressure-sensitive adhesives Int. J. Adhes. Adhes. (IF 3.4) Pub Date : 2023-12-29 Adrian Krzysztof Antosik, Karolina Mozelewska, Marlena Musik, Piotr Miądlicki, Joanna Sreńscek-Nazzal, Katarzyna Wilpiszewska
Novel silicone pressure-sensitive adhesives containing modified montmorillonite were obtained, and subsequently, one-sided tapes were prepared. The novel adhesives were characterized by a higher tack, peel adhesion, and cohesion at room and elevated temperature when compared to the system without the filler. Adding modified fillers allowed to improve the thermal resistance of adhesive - the maximum

Improvement in BHETA yield by aminolysis and its application in hot melt adhesive Int. J. Adhes. Adhes. (IF 3.4) Pub Date : 2023-12-28 Abhinav K. Singh, Karan Chugh, S.T. Mhaske
Polyethylene terephthalate (PET) recycling has been carried out by various methods, e.g., mechanical recycling, chemical recycling, and energy recovery method. In this study, chemical recycling of PET was carried out by aminolysis using ethanolamine and converted into bis(2-hydroxyethyl) terephthalamide (BHETA). We have studied the effective polymeric catalysis of the aminolytic depolymerization of

Properties of wheat gluten based wood adhesives enhanced by transglutaminase and epichlorohydrin Int. J. Adhes. Adhes. (IF 3.4) Pub Date : 2023-12-28 Zhenyuan Li, Fusheng Chen, Boye Liu, Mei Du, Lina Wu, Tingting Zhang
Bio-based eco-friendly products are well-received globally due to increasingly scarce petroleum resources and growing public concern about human health risks and environmental concerns. In this study, wheat gluten (WG) as the raw material modified with transglutaminase (TGase) and epichlorohydrin (ECH) was used to develop an eco-friendly bio-based adhesive. Effects of TGase and ECH on the properties

Surface modification of epoxy resin by MnO2–H2SO4–H2O–Na4P2O7 for enhanced adhesion to electroless copper Int. J. Adhes. Adhes. (IF 3.4) Pub Date : 2023-12-28 Wenxia Zhao, Xin Liu, Xuan Song, Caifang Zhang, Huaijun Chen, Xinwei Li, Kaihong Hui, Wei Zhao, Liang Qiao, Hao Zhu, Yi Cheng, Zenglin Wang
The purpose of this study was to enhance the adhesion strength between the epoxy resin (EP) substrate and the electroless copper plating layer by utilizing a MnO2–H2SO4–H2O–Na4P2O7 system for surface modification. The effect of the volume ratio of VH2SO4:VH2O and the duration of surface modification on various surface characteristics and adhesion strength was examined. The results provide valuable

Failure analysis of crack-prone joints with Finite Fracture Mechanics using an advanced modeling approach for the adhesive layer Int. J. Adhes. Adhes. (IF 3.4) Pub Date : 2023-12-27 T.S. Methfessel, C. El Yaakoubi-Mesbah, W. Becker
When adhesive joints are subjected to critical loads, the components can separate at the interface between the adhesive layer and one of the adherends. Due to the strongly differing stiffness properties of the adherends and the adhesive, which cause stress peaks to arise locally at the edge of the joint, a crack grows into the structure there once the critical load is reached. The concept of Finite
