Installation of Dynamic Stiffness Tester in Brazil

Standard International Group (HK) Limited has successfully completed the installation of a Dynamic Stiffness Tester in Brazil. This installation demonstrates the strong suitability of the Dynamic Stiffness Tester for the aerospace composite materials sector in Brazil. This cooperation is more than a simple equipment delivery; it marks the successful entry of China’s high-precision dynamic mechanical testing equipment into the South American aerospace supply chain.

Why Does the Dynamic Stiffness Tester Stand Out

Non-Contact High-Frequency Excitation Technology: Perfectly Suited for Thin-Walled Composite Materials

Unlike traditional contact-type extensometers, the DST employs a combined technology of air-coupled ultrasonic excitation and Laser Doppler Vibrometry (LDV).For the 1.2 mm-thick carbon fiber/PMI foam sandwich structure used by SulAmérica Composite Solutions, this technology addresses a major industry challenge: contact forces can cause localized deformation, resulting in inaccurate measurements of the material’s true stiffness.The measurement error is controlled within ±0.8%, while competing products generally have errors of ±3.5% or higher.

Unique Dynamic Compensation Module for Humid and Thermal Environments

Considering the high humidity and significant temperature variations throughout the year in the São Paulo region of Brazil, the DST incorporates a real-time temperature and humidity dynamic compensation algorithm.This algorithm automatically eliminates the effects of environmental factors on the calculation of the damping ratio and storage modulus, ensuring a high level of repeatability between test results obtained at 10:00 a.m. and 2:00 a.m.The resulting GR&R value is ≤10%, which was a key reason why the laboratory ultimately selected our equipment.

“User-Friendly” One-Click Airworthiness Report Generation

The DST operating system comes pre-installed with a complete set of report templates designed to meet NADCAP and ANAC requirements.Engineers simply need to click “Generate Report,” and the instrument can automatically generate a PDF report containing:Measurement uncertainty analysis,Calibration traceability,Statistical Process Control (SPC) charts.

The quality manager at SulAmérica stated:“This saves us at least 8 hours of manual data processing and format adjustment every week.”

Modular Calibration Standards and Remote Expert Database Support

The equipment is supplied with a set of composite stiffness reference blocks with indirect traceability to the Brazilian National Institute of Metrology.Through our after-sales service system, engineers can also access the Global Composite Material Stiffness Database.When a new resin system is encountered, SulAmérica’s engineers can initiate a remote expert consultation with one click and obtain recommended test parameter presets, eliminating the need for repeated destructive trial-and-error testing.

Significant Lifecycle Cost Advantages

Compared with German competitors that require expensive laser sources to be replaced annually, the DST uses a solid-state, long-life laser source with a designed service life of 100.000 hours.Routine maintenance requires only:Cleaning the air filter once a week,Wiping the optical window once a month.According to our calculations, the DST's total cost of ownership over five years is approximately 42% lower than that of comparable U.S. competitors.
