    Surface modification of superdrawn polyoxymethylene fibres (1994)

    Notes: Abstract The pull-out fracture of surface-modified superdrawn polyoxymethylene fibres embedded in rubber is discussed from a fractographical viewpoint. The morphologies of the pull-out fracture plane were very similar to those of the fracture surface in single lap-joint tests and the true pull-out stress coincided with the shear strength of a single lap-joint, indicating that the pull-out failure is strongly related to single lap-joint shear fracture.

    Effects of surface treatments of superdrawn polyoxymethylene fibers on adhesion to epoxy resins (1996)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: Strong adhesion in the superdrawn polyoxymethylene (POM) fiber/epoxy matrix system was achieved with surface treatments, 2H-hexafluoro-2-propanol (HFP) treatment, and surface phenolation of the fiber. HFP produced micropits for mechanical interlocking with the matrix. Surface phenolation formed active layers leading to interfacial miscibility. © 1996 John Wiley & Sons, Inc.

    Effects of drawing on creep parameters of polyoxymethylene-drawn fibers (1995)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 33 (1995), S. 179-187

    Notes: The effects of drawing on creep parameters (modulus, viscosity, and retardation time) of polyoxymethylenedrawn fibers were examined on the basis of a series-parallel, four-element, mechanical model. These parameters increased with the draw ratio. The change in the modulus was the same between the series and parallel components. This was true also for the viscosity, although the change in the viscosity was much greater than that in the modulus. This means that the series and parallel components are deformed in the same mode by drawing. The parallel viscosity increased with elapsed loading times according to an experimental power function; this was also derived from the usual rate equation for viscosity change in the amorphous component. In contrast, the series viscosity remained unchanged over the short creep range due to an extremely larger value than that of the parallel. © 1995 John Wiley & Sons, Inc.

    Mechanical properties and structure relationships in drawn fibers of elastomer-polyoxymethylene blends (1997)
    Bognor Regis [u.a.] : Wiley-Blackwell
    Journal of Polymer Science Part B: Polymer Physics 35 (1997), S. 107-118 
    Details
    ISSN: 0887-6266

    Notes: Superdrawn fibers of an elastomer-poly(oxymethylene) (POM) blend have been prepared and investigated in terms of the structure and mechanical properties. The development of the mechanical properties along the fiber axis and the formation of a higher order structure during drawing were slightly retarded by blending, but the loop tenacity increased greatly with the elastomer content. The blend microtextures had an immiscible and phase-separated morphology in which the elastomer was dispersed in the form of streaks between the oriented POM layers, which allowed the fiber to split into smaller filaments on bending. The high loop tenacity of the blend fibers is due to an increase in the radius of curvature resulting from the filament splitting on bending, because the shear stress at the bending corner becomes higher as the radius of curvature increases. © 1997 John Wiley & Sons, Inc.

    Characterization of dehydrochlorinated poly(vinylidene chloride) and the shock-compressed material (1995)
    Weinheim : Wiley-Blackwell

    Notes: Dehydrochlorinated poly(vinylidene chloride) proved to be a conjugated polyene-polyene polymer. Shock compression of the polymer formed a large portion of graphite and trace amounts of diamond and of an unknown carbon. The unknown carbon belongs to the hexagonal crystal system and possesses the cell dimension α0 = 0.338 nm. A comparison with known carbynes was made in terms of the crystalline parameters.
