    Notes: [Auszug] The travelling-wave-tube analogue was described in detail in a recent paper1, and is based on the lumped circuit travelling-wave tube first described by Matthews2. Briefly it consists of a series of drift tubes inside a vacuum envelope interconnected with a series of inductance coils which are ...

    Notes: [Auszug] Mahieu has demonstrated1 that there are electrical and luminescent effects associated with .the failure of glass reinforced resins. He showed that current changes of between 10~12 and 10-10 A occurred both in the direction of the bias current and/or in opposition to it when a tensile specimen was ...

    A bend-testing stage for the scanning electron-microscope (1970)
    Springer
    Journal of materials science 5 (1970), S. 873-880 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The design of a stage to bend materials in a scanning electron-microscope (Stereoscan, Cambridge Scientific Instruments Ltd) is described together with examples of its use in the fracture of composite materials. The bend module, when fitted to a large modular stage, can be used with existing scanning electron microscopes and is capable of bending, under increasing load or cyclic loading conditions, rectangular specimens of a maximum size 44×4×1.5 mm, to a maximum strain of 1.5%. Using the module with a standard display system the non-catastrophic stages of deformation and failure can be followed at higher magnification than has previously been possible. When the module is used in conjunction with a fast scanning and display system, deformation and fracture processes may be recorded at high magnifications while the specimen is being strained.

    The development of composite carbon fibres of large diameter—macro fibres (1974)
    Springer
    Journal of materials science 9 (1974), S. 835-844 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract This paper describes the development of a process for manufacturing carbon fibres of larger diameter than those normally available from the “RAE process” [1] or other routes which have so far been described (e.g. the hot-stretching of pitch [2] or cellulose-based [3] fibres). The method consists of impregnating a bundle of carbon fibres or their precursors with resin and after curing, subjecting the composite fibre to a controlled carbonization. The end-product is a thin rod or fibre of carbon-fibre reinforced carbon, which can, in principle, have any desired cross-sectional shape or area [4]. Experiments have been conducted to discover the effect of various processing variables on the properties of the composite fibre. Having chosen a suitable resin for impregnation the principal variables are (a) the degrees of pyrolysis of the initial fibre before impregnation, (b) the rate of cure of the resin to form the “intermediate” and (c) the rate of temperature rise and the maximum temperature during the carbonization process. Fibres of reasonable properties (Young's modulus 76.8 GN m−2 and ultimate tensile strength of 267 MN m−2) have been produced but improvements should be obtainable by optimization of this basic process as fibres with strengths up to 400 MN m−2 have been observed.

    Assessment of damage in GRP laminates by stress wave emission and dynamic mechanical measurements (1977)
    Springer
    Journal of materials science 12 (1977), S. 2329-2342 
    Details

    Notes: Abstract Stress wave emission (SWE) and dynamic mechanical methods are described for monitoring the damage introduced into certain glass fibre-reinforced epoxy specimens by the application of a tensile load. For one particular composite system, a cross-ply laminate, it was possible to measure the concentration of damage by an independent optical method and correlations have been found between the SWE and dynamic mechanical results and the area of cracking. It remains to be established whether these correlations apply to other reinforcement geometries. This work is considered a first stage towards using these methods for monitoring the integrity of a component in service, from which its remaining life might be assessed.
