Shear-thickening fluids (STFs) can be subjected to a significant temperature variation in many applications. Polymeric or oligomeric are commonly used as suspending media for STFs. Because the viscosities of polymeric strongly temperature-dependent, large changes profoundly affect shear-thickening responses. Here, effect on behavior four low-molecular-weight glycols/fumed silica suspensions is reported. The dispersed-phase volume fraction, its surface chemistry, and chemical compositions...
Tailorability is an important advantage of composites. Incorporating new bio-reinforcements into composites can contribute to using agricultural wastes and creating tougher more reliable materials. Nevertheless, the huge number possible natural material combinations works against finding optimal composite designs. Here, machine learning was employed effectively predict fracture toughness properties multiscale bio-nano-composites. Charpy impact tests were conducted on with various two bio...
Material property characterization tests were performed on satin weave carbon/epoxy composites, where the epoxy resin was modified with 2 wt% carbon nanofibers prior to infusion into a continuous fiber preform. Uniaxial tension tests, tension-tension fatigue and fracture initially 0–3 nanofibers-reinforced specimens in order determine nanofiber weight fraction leading optimal mechanical properties of matrix. In general, elastic modulus increased increasing fraction. The ultimate tensile...
A micromechanics parametric study was performed to investigate the effect of carbon nanofiber morphology (i.e. hollow vs. solid cross-section), waviness, and both nanofiber–resin interphase properties dimensions on bulk nanocomposite elastic moduli. Mori–Tanaka self-consistent models were developed for composites containing heterogeneities with multilayered coatings. For a given axial force–displacement relationship, modulus nanofibers can significantly exceed that resulting in notable...
