Polymer and composites testing instrument IMPULSE–R


FIELD OF APPLICATION
        The installation IMPULSE-R is applied for polymer testing and comparative analysis of physico-mechanical properties of wide range materials (composites, plastics, rubber, elastomers, bilogical tissue, cartiladge), which are used in the industry and medicine. The modern computerized method and installation allows in a few seconds to get the information about the hardness (Shore A, IRHD ISO 48, ISO 1400), resilience (rebound ISO/R 1767), coefficient of the viscosity, stiffness, dynamic elastic modulus, relaxation modulus.
        IMPULSE-R allows to investigate properties of different materials under impact loading on micro-level. The installation provides a continuous curve of the force, velocity, penetration versus time and curve of the contact force versus penetration.
        IMPULSE-R is ideal for testing time-dependence materials. It allows to determine the information, which is not available in traditional tests.
        IMPULSE-R gives whole information about mechanical properties of material tested and provides measurement in different test condition (different temperature or loading rates). Measurement with IMPULSE-R is repeatable unlike destructive instrumented impact tests. The use of these data makes it possible to predict the behavior of a material under the most complex operating conditions.
        The installation is applied in many companies in Russia and Europe.
PRINCIPLE OF OPERATION
        The device is based on dynamic indentation method - local impact loading of the material tested; recording of the analog signal of indenter’s displacement; its analog-to-digital conversion and calculation of the mechanical characteristics of the material tested, using special algorithms. Various models of loading system are enable to measurement properties of different materials (polyvinylchloride, plastics, foamed polyurethane, and rubber) and monitor manufacture polysurface products—cable, gasket, grommet etc.
DESIGN
        Installation interface – Com-port (RS 232). Operation system- Windows 98/2000/XP, RAM 64 MB. The installation works when connected to a computer (not included in the delivery set).
ADVANTAGES
        IMPULSE-1R gives whole information about mechanical properties of material tested and provides a better characterization of measurement in different test condition (e.g. different temperature or loading rates). Measurement with IMPULSE-1R is repeatable unlike destructive instrumented impact tests.
