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.
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).
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.
