General Description 

The STFA is an advanced paper test instrument used for testing and evaluating mechanical properties of planar type materials such as paper, plastics, corrugated, composites, textiles, elastomers, etc. 
The load frame (load control) applies mechanical force and measures the resulting stress. 
An Extensometer provides strain data allowing load related data analysis. 


Applications

A paper test lab certifying their product.
A research organization testing recycled material properties.
A packaging company simulating corrugated box performance.
A fabric manufacturer testing strengths.


The tests can be conducted under various environmental conditions.  Relative humidity is not controlled, the RH and Temperature conditions are passive based on the room’s environment. 
The test types are as follows: 

Test Types

Load Such as tensile, compression, creep and stiffness
Short column (edgewise compressive corrugated fiberboard)  (required short column fixtures).


Electronics 

The STFA has few subsystems. 
The power is distributed through the main unit.  Basic 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 or higher precision. 

Software 

The Microsoft® Windows® based HMI (Human Machine Interface) software controls the STFA. 
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 manual clamps that are adjustable. 
The vacuum system provides sample restraint and air flow. 
Maximum air flow results in minimal restraint. 
The STFA consists of one unit, with additional components such as the computer. 


Key Benefits

In-plane compression testing.
Precision load system using load control.
Multitude of test types.
Modern computer control.




Sample Sizes

Standard load-based test 3.08cm x 15.3cm (1.21" x 6.02")  By special order (3.08cm X 17.78cm)
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 (Option) 5.1cm X 3.2cm (2" x 1.25".)  This sample size may vary depending on ultimate load potential, flute type etc.
Option 1 Pass through sample preparation punches
