ISSN: 1572-8935Keywords: Polypropylene (PP) ; Sago starch (SS) ; Miscibility ; Storage modulus (E′) ; Loss tangent (tanδ)Source: Springer Online Journal Archives 1860-2000Topics: Chemistry and PharmacologyMechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsPhysicsNotes: Abstract Sago starch (SS) was melt-blended with polypropylene (PP) with the concentration of SS in the blends varied between 10% and 50% by weight. Characterization of the PP/SS blends was carried out to gain some information on the miscibility between PP and SS and to gain insight into how well these materials behave thermodynamically with regard to the variation of the storage modulus (E′) and the loss tangent (tanδ) with temperature. The E′ and tanδ remained unchanged for SS between 10% to 33% but increased as SS reached 50%. The blend containing 50%SS was superior compared to the other blends in the dynamic mechanical thermal analysis (DMTA). Through the use of a Differential Scanning Calorimeter (DSC), the melting endotherm of the miscible blends was found to increase constantly with the increasing SS content. The tensile properties of the blends decreased with SS content. Examination of the blends with a Scanning Electron Microscope (SEM) showed that the SS granules were well dispersed in the PP matrix.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-4803Source: Springer Online Journal Archives 1860-2000Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision MechanicsNotes: Abstract The mechanical properties of polyetheretherketone and polyetherketone were studied as a function of strain rate and temperature in the ranges 10−3 to 103s−1 and 20–200°C. At temperatures below the glass transition temperature, T g, the strain-rate sensitivity of both polymers was found to be almost independent of temperature with a value of ∼4 MPa per decade of strain rate and the behaviour was well described by an Eyring relationship leading to an activation volume of ∼1 nm3. Above T g, X-ray and differential scanning calorimetry studies show that cold-crystallization phenomena play a very important part in the polymer behaviour, leading to an increase of yield stress with increasing temperature. The crystallization was found to be highly strain-rate dependent with no increase in crystalline content occurring in quasi-static tests and increases of up to 20% in higher rate tests. Much of the data have been gathered using novel test equipment which is described in the paper.Type of Medium: Electronic ResourceURL: -

ISSN: 0029-5981Keywords: Engineering ; Engineering GeneralSource: Wiley InterScience Backfile Collection 1832-2000Topics: MathematicsTechnologyNotes: A series of direct-integration and model-expansion finite element algorithms for a geometrically and materially nonlinear elastodynamic problem are constructed and analysed. The algorithms are constructed by temporally approximating the individual nonlinear stiffness terms such that discrete conservation laws are obtained. This conservative property has a positive effect in providing a stable appromixation, and in addition allows the stability properties of the algorithms to be easily assessed. Stability and convergence criteria for the algorithms are rigorously established using an energy method.Additional Material: 3 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 0887-6266Keywords: PEEK ; PEK ; crystallinity ; strain rate ; Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: This work extends the results of previous workers on the influence of drawing on the crystallinity of PEEK and PEK to test temperatures well above Tg and to strain rates up to 103 s-1. The study thus includes measurement of crystallinity in samples tested in the strain rate regime where large increases in flow stress have previously been noted in these and other polymers. The results are in reasonable agreement with other workers on PEEK and are representative of the behavior of both PEEK and PEK at temperatures up to 200°C and strain rates up to 102 s-1. However at a strain rate of 103 s-1 a dramatic increase in crystallinity and reduction in d-spacing is observed. It is speculated that a change in crystalline morphology induced by the high rate testing may account for the observed changes in spacing, crystallinity, and flow stress. © 1996 John Wiley & Sons, Inc.Additional Material: 4 Ill.Type of Medium: Electronic Resource
