“…It is known that plasma cleaning can increase the polarity of steel surface and thus surface energy. 39–41 The increase in polarity, combined with the smoothness of surface, makes steel an ideal substrate for most adhesives. This can be seen with adhesion strength of over 2.0 MPa for many of the adhesives with lignin contents at 50 wt% and 75 wt%.…”

“…Under normal circumstances, the adhesive will undergo a series of physical and chemical changes after absorbing water, such as swelling, softening, plasticizing, microcracking, degradation, and so forth, which reduces the mechanical properties and durability and is also the main reason for the decline in bonding performance. [ 29 ] By applying the modified Bis‐GMA in the adhesive, the water absorption value and solubility value of the adhesive are significantly reduced, and a good solution can be put forward to the above‐mentioned clinical use problems.…”

“…If the adhesive is highly hydrophilic, it will absorb the moisture in the saliva, resulting in a series of physical changes such as swelling, softening, plasticizing, microcracking, and degradation inside the adhesive, which will affect the long‐term service of the adhesive performance. [ 29 ] If the adhesive is too hydrophobic, it cannot bond well with the dentin, reducing the bonding strength. [ 30 ] Therefore, in this experiment, the contact angle of the adhesive before and after the modification of Bis‐GMA was tested by a contact angle tester (XWK‐705B, SIVAKA, China).…”

In recent years, zirconia repair materials have developed rapidly and are now widely used in the preparation of dental restorations such as crowns, veneers, and bridges. Zirconium oxide has excellent mechanical properties and excellent biocompatibility. However, the inertness of itself determined that it cannot bond well with dental hard tissue, and the high volume shrinkage of the adhesive also results in poor bonding. In this article, bisphenol‐A‐glycerol dimethacrylate (Bis‐GMA) was acetylated, and a light curing acrylate‐based adhesive with high bonding strength was prepared. The volume shrinkage of the adhesive prepared by modified Bis‐GMA decreased, the shear bonding strength increased, and the double‐bond conversion and thermal stability of the adhesive were improved. This article compares the self‐prepared adhesive with the Single Bond Universal produced by 3M and All‐Bond Universal produced by Bisco. The results show that the self‐prepared adhesives are superior to the two commercial adhesives in terms of shear bonding strength, water absorption value, solubility value, and volume shrinkage.

Application of composite patches is a useful technique to repair damaged structures such as wind turbines, air vehicles, pressure tanks because of lightweight, flexible design, and low price, and have found a widespread application area in many more industries. To avoid excessive weight of the repaired region as well as unnecessary material consumption composite patches need to be optimized according to shape, size and material specifications. This paper introduces a numerical assessment of size and material effect in composite-to-composite patches having specific shape and material properties. Adhesively bonded round-tipped composite patch pieces are utilized to repair a quadrilateral puncture damaged cylindrical thin-walled hollow composite tubes loaded by internal pressure. Glass fiber / epoxy patches with five different kinds of stacking sequence and ten different sizes are numerically investigated to achieve the best composite patch solutions. Although the safety factor of repaired tubes enhances by increasing tip radiuses and hence their sticking area, it is found to be not sufficient to ensure that the patching process is completely safe because of the fiber orientation playing an important role on the factor of safety. The patches having [0˚]4, [0˚, -45˚,45˚,90˚], and [0 ˚,90 ˚]2 stacking sequences and having adequate patch areas are found to be able to provide the safety value of “1.15” which is defined for normal safety class and below 5% coefficients of variation (COV) value in DNV’s Offshore Standard (DNV-OS-C501).
