Micro-mechanical deformation mechanisms in the fracture of hybrid-particulate composites based on glass beads, rubber and epoxies
(Wiley Subscription Services, Inc., A Wiley Company, 2000-12)
Two tougheners, glass beads and carboxyl terminated butadiene acrylonitrile copolymer (CTBN), are used to toughen and stiffen an epoxy thermoset. Rubber-encapsulated glass beads are used and the hybrid particulate composites ...
Hydrodynamics and microphase ordering in block copolymers: Are hydrodynamics required for ordered phases with periodicity in more than one dimension?
(The American Institute of Physics, 2004-12-08)
We use Brownian dynamics (BD), molecular dynamics, and dissipative particle dynamics to study the phase behavior of diblock copolymer melts and to determine if hydrodynamics is required in the formation of phases with ...
Ion beam modification of metals: Compositional and microstructural changes
(Elsevier, 1989)
Ion implantation has become a highly developed tool for modifying the structure and properties of metals and alloys. In addition to direct implantation, a variety of other ion beam techniques such as ion beam mixing, ion ...
Curing reaction and product properties of polysulfones terminated with active functional groups
(Wiley Subscription Services, Inc., A Wiley Company, 1991-11-20)
The curing processes of maleimide-terminated polyether sulfone oligomers ( M n from 1100 to 3000) and ethynyl-terminated polysulfone prepolymers ( M n from 2600 to 12000) were investigated by means of DSC. The ...
Monte-Carlo simulations of spinodal ordering and decomposition in compositionally modulated alloys
(Materials Research Society, 1990)
Effect of fiber inclination on crack bridging stress in brittle fiber reinforced brittle matrix composites
(Elsevier, 1992-08)
behavior of brittle matrix composites is strongly affected by the bridging of cracks by fibers. In random fiber composites, fibers can lie at an angle to the crack plane. Under such conditions, the bridging stress for a ...
The annealing and thermal analysis of poly(butylene terephthalate)
(John Wiley & Sons, Inc., 1994-04-15)
When poly(butylene terephthalate) (PBT) is annealed, a second endotherm is often displayed in a subsequent scanning thermal analysis at a temperature below that of the original endotherm, and this new endotherm appears to ...
The interdependence of stress and interdiffusion during solid-state amorphization in Ni-Hf
(Materials Research Society, 2000)
Effects of material properties and crush conditions on the crush energy absorption of fiber composite rods
(Elsevier, 1993)
Crushing along the fiber axis of undirectional E-glass fiber composites rods was examined to determine the effects of fiber volume fraction, fiber diameter, matrix compressive yield strength, crush rate, fiber surface ...
Vapor-based polymer coatings for potential biomedical applications
(John Wiley & Sons, Ltd., 2006-12)
Over the last decade, biology and biotechnology have witnessed an extraordinary development spanning genomics, proteomics, and metabolics. This progress was so rapid and definite that it not only changed the face of modern ...
