Inspired by the remarkable adhesion mechanisms of marine mussels, recent studies have explored biomimetic strategies—such as dual crosslinking, organic-inorganic hybridization, and sacrificial bond mechanisms—to enhance the bonding strength and water resistance of SP-based adhesives. This review examines the effectiveness of these mussel-inspired modifications compared to conventional crosslinking approaches in SP adhesives. Surprisingly, the improvements in adhesive performance, particularly in terms of bonding strength and water resistance, were only marginally superior to those achieved through non-biomimetic modifications. This finding suggests that while mussel-inspired strategies offer valuable insights, further refinement is necessary to fully harness their potential. Specific technical directions, such as designing SP-specific mussel-inspired peptide segments, incorporating catechol-functionalized crosslinkers, and optimizing redox-responsive or pH-sensitive bonding mechanisms, represent promising routes for improvement. By critically evaluating these approaches, this review also highlights opportunities for advancing SP-based adhesives through novel crosslinking techniques, cost-effective formulations, and processing methods.

The W-Mn-Cu-Sn alloy particles were produced via mechanical alloying (MA). MA is a process that involves repeated cycles of cold welding, fracturing, and re-welding of powder particles, producing fine, homogeneous materials with improved properties. This technique plays a vital role in uniformly dispersing particles within the tungsten matrix, thereby enhancing the alloy's mechanical properties. The mean diameters of each sample were determined from statistical analysis of 33 measurements using ImageJ software, resulting in an average diameter of 245 nm. Furthermore, the particle size distribution predominantly ranged from 121 to 439 nm. The crystallographic characteristics of the powders were analyzed using X-ray diffraction (X'Pert PRO, Malvern PANalytical) with CuKα radiation (λ = 0.15406 nm). In all samples, the most prominent diffraction peak corresponds to the W phase and the nanoparticles were dispersed in Araldite 2014 using a combination of probe sonication and high-speed mechanical mixing. Single-lap shear tests were applied to SLJs prepared with 1.0 %, 3.0 %, 5.0 %, and 7.0 % tungsten alloy (WAs) additive ratios by weight. The results show that incorporating W-Mn-Cu-Sn nanoparticles enhances the adhesive's mechanical properties, as evidenced by increased shear strength and toughness. The maximum shear strength was observed in specimens with 5.0 wt% W-Mn-Cu-Sn nanoparticles, which exhibited a 21.7 % improvement compared to the neat adhesive. The failure modes of the joints changed from mixed-mode failure to cohesive failure with increasing nanoparticle content, indicating improved adhesion and load transfer between the adhesive and the GFRP substrates. The SEM images indicate that the fracture surfaces of tungsten alloy (WAs) modified specimens exhibited ductile failure modes. Due to the formation of plastic voids and mechanisms for crack deviation, the fracture toughness and shear strength of the modified adhesive have improved.

Structurally integrating glass into yacht structures offers a solution to this. However, this requires a rigid and reliable connection between glass and metal components, which needs to be validated.

First, tensile tests on dumbbell specimens are conducted at crosshead speeds of 0.1, 1, 10 and 50 mm/min and temperatures of −20, 23, 50 and 80 °C. Results show that both stiffness and strength increase with strain rate but decrease with increasing temperature, with significant loss at 80 °C. Second, shear tests on double-lap glass-to-steel specimens evaluate adhesion, using a bond thickness of 7 mm to accommodate geometric tolerances in a ship. This thickness is significantly larger than what is recommended by the manufacturer for maximum bond strength. Third, ageing tests are performed on dumbbell and double-lap specimens stored at 50 °C ± 1 °C and 94 ± 1 % relative humidity for six weeks. After ageing, tensile strength and stiffness of the epoxy reduced by 24 % and 51 %, respectively. While double-lap specimens exhibited reduced stiffness after ageing, the scatter on results could not be used to quantify stiffness and strength reduction. During the ageing period the amount of water absorbed by dumbbell specimens was estimated by weighing the specimens periodically. A correlation was found between amount of absorbed water and degraded properties. Based on its high strength and stiffness, epoxy has potential for structural glass-to-steel bonding.
