CYCOGS® brand, VCA TFA Vacuum Compression Apparatus, Thin Film Analyzer material technology testing platform

contain numerous sensors and additional sensors can be embedded.  Such additional sensors may include optical moisture content, moir'e optical pattern analyzers and other sensors that may be needed.


General Description 

The VCA TFA is an advanced paper test instrument controlling relative humidity for testing and evaluating mechanical properties of planar type materials. 
Such materials include paper, plastics, corrugated, composites, textiles, elastomers, etc.  The load frame (load control) applies mechanical force and measures the resulting stress.  Extensometers provide strain data allowing data analysis of yield, energy, modulus and Poisson's ratio. 
Sample measurements include load, and the X, Y, and Z deflections. 


Dimensional stability test setup on paper with three extensometers. 


A paper test lab certifying their product.
A research organization testing recycled material properties.
A packaging company simulating corrugated box performance.
An electronics company testing for moisture effects.
A fabric manufacturer testing moisture related strengths.
A publisher solving ink registry problems caused by dimensional changes during printing.
An adhesive label manufacturer analyzing humidity effects on glued paper.

Test Types 

The tests can be conducted under various environmental conditions. 
Relative humidity profiles include steady state, steady state plus steps, square wave with ramp control (trapezoid), sine wave, saw-tooth (triangle) wave, swept frequency waves. 
Custom profiles such as actual recorded data from a process or warehouse can be used. 

The test types are as follows:
Load Tensile, compression, creep, stiffness, biaxial  (required biaxial test frame).
Short column (Edgewise compressive corrugated fiberboard)  (required short column fixtures).
Dimensional stability (Four axis, X, Y, XY and Z).
Moisture migration Curl, air permeability studies.

The TFA VCA has numerous subsystems.  The power is distributed through a high current sub-panel located in the utility cart.  The test unit also contains an uninterruptible power supply, computer and electronics.  Numerous sensors allow the real world to interface with the computer.  The computer is a current generation running Microsoft® Windows®.  The analog interface electronics uses 16-bit precision. 

System Software 

The Microsoft® Windows® based HMI (Human Machine Interface) software controls the TFA.  Concurrent multithreaded processes ensure high level of performance and self-monitoring.  The program running on Microsoft® Windows® is custom designed for this machine.  Basic data storage is in the form of an ASCII text comma separated values  (CSV) file that can be read by any software that can read a text file.  The custom software semi-automates sensor calibration.  Data can be played back with a second program using a similar screen for review or demonstrations. 


Other Information 

The internal load frame uses hydraulic clamps that are pressure adjustable. 
The external load frame (biaxial) uses glue tabs. 
The vacuum system provides sample restraint and air flow. 
Maximum air flow results in minimal restraint. 
The VCA TFA consists of two units.  
The first component is called the Test Unit. 
The second unit is called the Utility Cart. 
The Utility Cart contains heat and noise generating devices such as motors, pumps, dehumidifier, etc.
that can be located remotely from the Test Unit. 
The two units are connected with umbilical cables and pipes. 
The separation distance between the two components depends on the application and the installation configuration.

High Load test May require a necked (dog bone) sample, depending on expected load: necked down to 1.50 cm (0.59.")
Minimum Thickness The actual material properties will determine the minimum thickness.
Maximum Thickness 3mm (0.12"), depending on clamp foot design.
Short Column test 5.1cm X 3.2cm (2" x 1.25".) This sample size may vary depending on ultimate load potential, flute type etc.


VCA TFA Load test setup. 

Load Range

Internal Load Frame capacity: ±1.3344kN (300 lbf)
External Load Frame (Biaxial) capacity: ±444.8 N (100 lbf).
Load Control: 16 bits resolution. NOTE: this device's cross head motion uses load control.  Load ramp rates User selected;  computer generated.
Calibration: 444.8 N (100 lbf) load ring standard.
Option 1: Biaxial test frame and fixture (external load frame).
Option 2: Short column test fixtures.
Option 3: Pass through sample preparation punches.


Precision extensometers are used for motion sensing.
Most load tests: One or two are used.
Dimensional stability test: Uses three extensometers.
Typical setups: 25.4mm (1") gage length 10% extensometers.
A/D conversion: 16-bit resolution.
Z direction data: Uses a DVRT sensor.
Option 1: 25.4mm (1") gage extender for 5% operations.
Option 2: 1 - 2mm (micron level) Z direction or precision measurements.
Option 3: Optical measurements.


Test Software

Option 1: Microsoft® SQL Server® data storage.
Option 2: Internet enabled remote monitoring and email event notification.
Option 3: Robotic specimen loading.

Relative Humidity 

The standard setup in a 22.8°C (73°F) 50% room will control (depending on proper test setups) 25% to 95% RH (non-condensing). 
A typical accelerated load test may use a 10 minute 30%-90% sinusoid control ramp. 
Faster square wave cycles are possible; however, the system response may not follow the square wave input within the 2% target. 

Relative Humidity
Option 1: Below 10% operations.
Option 2: Above 95% operations - Condensing water may result in control issues.
Option 3: Optical moisture sensor.
