Carbon fiber reinforced polymer (CFRP) composites are increasingly utilized for their lightweight and superior mechanical properties. This study uses machine learning models to predict the properties of CFRP based on volume fraction carbon nanotubes (CNTs), interlayer fraction, glass transition temperature, manufacturing pressure. Sixty-two samples covering nine different types CFRPs were designed, manufactured, experimentally tested. Three models, namely ridge regression, random forest,...
A lumped-parameter, analytical model of material and thermal transfer is established in this paper for metal deposition by a moving, concentrated source. This dynamic description the distinct width, height, length, temperature ellipsoidal molten puddle, expressed with respect to torch power, feed angle, source motion. through scalar mass, momentum energy balances puddle control volume, conduction substrate. The validated GMA welding experiments, measurements an infrared camera laser...
Nanotubes made of boron nitride (BN) and carbon have attracted considerable attention within the literature due to their unique mechanical, electrical thermal properties. In this work, BN nanotubes, exhibiting high purity (>99%) similar surface areas (~200 m2/g), were systematically investigated for stability oxidation behavior by combining gravimetric analysis differential scanning calorimetry methods at temperatures up ~1300 °C under a synthetic air flow environment. The nanotubes...
The self-propagating reaction of nickel-aluminum thin film multilayers with a bilayer thickness ∼43 nm was investigated using high-speed optical camera and infrared thermometry. results indicate two-stage two different characteristic temperatures. Following ignition, the flame front propagates near reverse peritectic transformation temperature Ni2Al3 into NiAl liquid at 1406 K. continues growth until melting 1911 K is reached. mechanism kinetics are discussed.
The observation of rapid reactions in nanoscale multilayers present challenges that require sophisticated analysis methods. We high-resolution situ x-ray diffraction foils Ni0.9V0.1–Al using the Mythen II solid-state microstrip detector system at Material Science beamline Swiss Light Source Synchrotron Paul Scherrer Institute Villigen, Switzerland. results reveal temperature evolution corresponding to formation NiAl intermetallic phase, vanadium segregation and stresses during cooling,...
In this study, we performed simulations of self-propagating reactions nanoscale nickel-aluminum multilayers using numerical methods. The model employs two-dimensional heat transfer equations coupled with generation terms from, (1) 1D parabolic growth intermetallic phases Ni2Al3 and NiAl in the thickness direction (2) phase transformations such as melting peritectic reactions. uses temperature dependent physical chemical data, interdiffusion coefficients, specific capacities, enthalpy...
Ultrasonic bonding of thin foils has been recently introduced to rapid prototyping complex-shaped and/or internally structured layered parts. This article provides the mechanical analysis an elementary ultrasonic spot welding process a metal foil on previously deposited substrate. A 2-D, quasi-static/dynamic, elasto-plastic numerical model stress/strain field is developed by finite element analysis. Its frictional boundary conditions at foil/substrate interface are described via simpler...
Nanofiber manufacturing is one of the key advancements in nanotechnology today. Over past few years, there has been a tremendous growth research activities to explore electrospinning for nanofiber formation from rich variety materials. This quite simple and cost effective process operates on principle that solution extracted under action high electric field. Once voltage sufficiently high, charged jet ejected following complicated looping trajectory. During its travel, solvent evaporates...
Autoclaving is a process that ensures the highest quality of carbon fiber reinforced polymer (CFRP) composite structures used in aviation. During autoclave process, consolidation prepreg laminas through simultaneous elevated pressure and temperature results uniform high-end material system. This work focuses on analyzing fundamental way applications separately during consolidation. A controlled vessel (press-clave) has been designed applies curing while being applied locally by heat...
Abstract The mechanical properties and hydraulic permeabilities of biomaterial scaffolds play a crucial role in their efficacy as tissue engineering platforms, separation processors, drug delivery vehicles. In this study, electrospun cellulose acetate fiber meshes random orientations were created using four different concentrations, 10.0, 12.5, 15.0, 17.5 wt % acetone or ethyl acetate. tensile the these measured, multiscale model was employed to predict behavior.
