Strain Gage Installation Checklist: COMPOSITE / PLASTIC / FIBERGLASS

Our new COMPOSITE / PLASTIC / FIBERGLASS checklist helps to ensure consistency and completeness in carrying out a strain measurement task.

Do you have strain measurements that you need to do again and again? If you do, how do you make sure that you do them correctly every time? One good solution, as it has been proven in many fields, is to use our new checklist. In fields like Automotive, Agriculture, building construction, aviation, and medical, the usage of a checklist can save a lot of time and can help stress analysts to do strain measurements more efficiently and avoid costly mistakes.

There is an ASTM (American Society for Testing and Materials) committee specifically dedicated to developing standards necessary for repeatable testing of composite materials. Committee D30 has created over 30 standards and guidelines for testing composites. ASTM D5379 (Shear Properties of Composite Materials by the V-Notched Beam Method) describes a unique test for determining shear modulus, and the line of Shear Modulus Gages developed by Micro-Measurements were designed around this test. ASTM D5450 (Transverse Tensile Properties of Hoop Wound Polymer Matrix Composite Cylinders) requires the use of rectangular rosette strain gage sensors, like the C2A-06-250WW-350 pattern.

So, if you do something like testing a composite, plastic or fiberglass again and again, and want to do it right every time, use a checklist.

A simple tool that helps to prevent these mistakes is the checklist. Our new checklist is simply a standardized list of the required steps developed for a repetitive strain measurement task on a COMPOSITE / PLASTIC / FIBERGLASS . 

Step 1: Define the Test Conditions

Step 2: Ensure Appropriate Surface Preparation Materials Are On Hand

Step 3: Select the Strain Sensor

Step 4: Select the Adhesive

Step 5: Select a Protective Coating

Step 8: Select the Measurement Instrumentation
