The response of aluminium and glass fibre FMLS subjected to blast loading
… aeronautics industry due to their exceptional strength to weight ratio, fatigue and impact resistance. Due to the increasing global risk of subversive activity in this industry, the focus of research in recent years has shifted to the blast resistance of these materials. A particularly …

Polymer impregnation and its effect on the rupture properties of leather
… polymer - leather interaction would increase strength. Surface properties of leather fibres were altered (using a hydrophobic agent based on a phosphate ester) to more closely match those of the polymer. This resulted in a more even distribution of polymer on the leather fibrils. Application …

Environmental Influence on the Bond Between a Polymer Concrete Overlay and an Aluminum Substrate
… purpose of this investigation is to evaluate the bond durability between the overlay and the aluminum substrate after conditioning specimens in various temperature and humidity conditions. The average critical strain energy release rate, Gcr, for each specimen was measured using a modified mixed …

Local Displacements and Load Transfer of Shape Memory Alloys in Polymeric Matrices
Average interfacial bond strength between an embedded SMA and an epoxy matrix were measured using pullout tests. The effects of various mechanical and chemical surface treatments on the bond strengths were examined. In-situ out-of-plane displacements of two-way trained SMA wires in epoxy were …

Compatibility and durability of concrete-stone system: The desert masonry at Taliesin West
… directly into concrete without intermediary bonding agents. This study focuses on two primary components of the system—face stone and concrete—whose direct contact and exposure to environmental conditions make them critical to the system’s performance. Unlike conventional stone veneers that …

Temperature-dependent tensile and shear response of graphite/aluminum
… Compared with rather high longitudinal strength, very low transverse strength was obtained for the graphite/aluminum. The poor transverse strength is believed to be due to the low interfacial bond strength in this material. The strength decreases significantly with increasing …

Engineering properties of ring shaped polytheylene terephthalate (RPET) fiber self-compacting concrete
… fibers. It has been shown that PET has a weak interfacial bond with cement paste in the pullout load because of the lamellar shape of fibers. Therefore, ringshaped PET (RPET) fibers are introduced in this study to overcome the limitations of traditional straight, lamellar, or irregularly shaped …

Multi-functional SMA hybrid composite materials and their applications
… elements for hybrid composite fabrication and interfacial bond strength is presented to address this issue. The mechanics of interfacial shear failure between SMA element and composite is also presented.

Physical mechanisms controlling the pre-failure stress-strain behavior of frozen sand
… particle size, stiffness, roughness, shape, and interfacial bond strength. Theories for composite material behavior are employed to analyze the observed stress-strain-time-temperature behavior. The stress-strain behavior has been measured in a high-pressure, low-temperature automated triaxial …

Effect of Surface Moisture Condition on Substrate-Repair Concrete Overlay Transition Zone
… in the world. Given its relative availability, strength, economy, and versatility to fit various applications, the material has been incorporated in roadways, bridges, buildings, and a host of other infrastructure projects. Oftentimes, concrete will be exposed to several environmental conditions …

Investigation of a heirarchical collagen scaffold/3D printed lattice structure designed for use in total knee replacements
… and properties of prepared samples, the bonds formed between FDM printed rasters were explored. Samples printed from poly lactic acid (PLA) and PEKK polymers were investigated. X-ray microtomography provided information on structural defects (including porosity) and tensile testing was …

Solvent-based self-healing approaches for fiber-reinforced composites
… matrices. Full recovery of interfacial bond strength after complete fiber/matrix debonding is achieved with a microencapsulated solvent-based healing chemistry. The surface of a glass fiber is functionalized with microcapsules containing varying concentrations of reactive …

Stimuli-responsive microcapsules for self-protecting and self-healing material systems
… emulsification technique is adapted based on the interfacial tension of immiscible phases for the fabrication of monodisperse emulsion templates and microcapsules. In this technique, either one (single emulsion) or two (double emulsion) dispersed phases are simultaneously delivered while …
