Evaluation of interlayer bonding in hot mix asphalt pavements
… (FWD) data for use in quantifying the level of interlayer bonding achieved in pavements. Data was obtained and used from the Federal Aviation Administration's (FAA) National Airport Pavement Test Facility located in Atlantic City, New Jersey. In this test facility, a section of the pavement had …

Improving the strength of fused filament fabrication parts by non-planar alignment of material extrusion wih stress vectors
… parts due to significant anisotropy and weak interlayer bonding. This thesis presents a novel approach to improve mechanical properties of FFF-produced parts through non-planar alignment of material extrusion with stress vectors. Research progresses from initial proof-of-concept studies to …

Study of Nozzle Design and Development of Reinforcing Mesh Approach for 3D Construction Printing
… important contributions to printed accuracy, interlayer bonding, and deformation resistance. Also, the key barriers faced in optimising nozzle-related parameters could be categorised into four aspects, namely: (i) technology, (ii) market, (iii) economic management, and (iv) social environment. …

Non-isothermal non-Newtonian flow and interlayer adhesion in Large Area Additive Manufacturing polymer composite deposition.
… layers which provides temperature along the interlayer bond line with respect to time. Infrared heating of printed beads, an addition to the current deposition process, is also modeled to determine the increase in temperature along the bond line for LAAM printing. Post deposition smooth and …

Topological defects in single and multi-layer graphene
… the effect of out-of-plane deformation and weak interlayer bonding on the mechanics of dislocations has not been fully studied. We focus on how dislocation mechanics appear in grain boundary migration and moir ́e patterns. For grain boundary migration, while the structure and energy of …

Applications of powder interlayers for large gap joining
… of damaged parts. Several methods using powder interlayers to produce large clearance transient liquid phase (TLP) joints have been developed and investigated in this work. One of the methods was using a mixture of powders of the melting point depressant (MPD) and the base material, from which a …

Development of a testing approach for tack coat application rate at pavement layer interfaces
Pavement interlayer bonding is one of the critical factors that affect the pavement service life. In addition to difficulties in compaction, lack of interface bonding can lead to serious pavement deterioration including slippage cracking, de-bonding, and early fatigue cracking, all of which …

Physics Based Modeling and Characterization of Filament Extrusion Additive Manufacturing
… the variety of applications. Additionally, poor interlayer adhesion results in anisotropic mechanical properties which can lead to failure, an issue not often observed in traditional manufacturing techniques. A review of the current state of the art research in the field of FFF, focusing on the …

Strength and Ductility of Concrete Cylinders Confined with Fiber Metal Laminate Composites
… to prevent brittle rupture and unpredictable debonding, buildings and bridges are strengthened in such a way that restricts their energy dissipation capacity at the ultimate limit state. This runs counter to the structural design philosophy of new buildings where the design objective is to …
