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 ...
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 ...
Morphology and primary crystal structure of a silk-like protein polymer synthesized by genetically engineered Escherichia coli bacteria
(Wiley Subscription Services, Inc., A Wiley Company, 1994-08)
The morphology and primary crystal structure of SLPF, a protein polymer produced by genetically engineered Escherichia coli bacteria, were characterized. SLPF is a segmented copolymer consisting of amino acid sequence ...
Crosslinking chemistry for high-performance polymer networks
(Elsevier, 1994-11)
A new thermally reactive monomer has been designed and synthesized that brings novel crosslinking chemistry to high-performance polymers. This monomer (XTA) is a derivative of terephthalic acid and was based on the thermal ...
Interactions of a liquid crystalline polymer with polycarbonate and poly(ethylene terephthalate)
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1997-01)
Thermal behaviour of blends of a liquid crystalline copoly(ester amide) (Vectra B950) with two isotropic polymers has been studied by differential scanning calorimetry. One of the isotropic polymers is an amorphous polymer ...
Temperature dependence of deformation-assisted crystallization in amorphous Fe78B13Si9Fe78B13Si9
(The American Institute of Physics, 1998-09-28)
Low-energy ball milling of amorphous Fe78B13Si9Fe78B13Si9 has been performed at temperatures between 25 and 250 °C. Primary crystallization is observed after milling at elevated temperatures, but not after annealing at the ...
Snubbing and Bundling Effects on Multiple Crack Spacing of Discontinuous Random Fiber-Reinforced Brittle Matrix Composites
(Blackwell Publishing Ltd, 1992-12)
