The ETEK 3000 is the world's foremost acoustic measurement
instrument for friction materials. Using ultrasonic
technology, the ETEK 3000 can measure all relevant elastic constants
of friction materials as well as composites. Currently, ETEK
elastic property data on new friction material formulations are required by
all major US automobile manufacturers.
The brake systems for new automobile models are often
specifically tailored to the individual needs of each model or
platform. Customer satisfaction is critically dependent on
braking free of noise, vibration and harshness.
Characterization of the brake components is needed for good NVH
characteristics.
To speed the development of new friction material formulations
and to design quiet systems, sophisticated models and simulations
have been developed. The predictive capability of these models
is dependent on accurate elastic property data, which can be
responsible for both the generation and propagation of noise and
vibration.
NVH characteristics of vehicles become increasingly important
factors in automobile development with advances in hybrid and
electrical drivetrain components, which while generally decreasing
the overall noise and harshness of a vehicle, allow for the noises
and vibrations of other components, such as the braking system to
become more noticeable and important.
The ETEK measurement system is positioned as the leader in
measuring relevant elastic property data for friction materials.
ETEK systems have been sold to brake development laboratories of
major US car manufacturers, first tier brake systems suppliers and
major friction material manufacturers through the world.
The ETEK 3000 measures all five independent
elastic constants for:
- Young's Modulus
- Shear modulus
- Poisson's Ratio
Features
- Controlled temperature measurement environment from
-25°C to 325°C
- Adjustable pre-load up to 1000N
- High speed data acquisition
- Advanced database and data management
- Advanced reporting features including automatic graph
generation and export to Microsoft Excel®
- Available load-dependent measurement package

IMS, Inc. also provides testing services with our
ETEK systems. We make measurements on the
ETEK using SAE specification J2725 with pre-loads from 5 to 55 bar
and temperatures from -25°C to 325°C. Our
Enhanced measurement procedure for friction materials provides
elastic and engineering constants as a function of temperature and
load. In addition, we make measurements on intact pads on multiple
positions using the iETEK.

In-line Quality Assurance testing of brake pads requires
automation in combination with rapid ultrasonic measurement. This
usage would allow ETEK technology to perform as a quality control
instrument.
