Report on the testing of compressive properties

ASTM D3410_Standard Test Method for Compressive Properties of Polymer Matric Composite Materials will move

Abstract/Summary

 

This section will include the following (and maybe some other stuff I missed?)

  • Highlight of results

  • What test we are doing (tensile, compression anvil pendulum etc.)

  • Some more specific information we missed, for example, we used our own equipment, we didn’t have the correct equipment so we had to choose something else, something that may have messed up our test results? (feel free to add other things you believe are important to note)

  • Lack of test specimens for the standard quantity that standards require?

  • Link to ASTM Standard summary?

 


 

Introduction

  

In this test, we will be using a compressive fixture to test various compressive properties of our CF sandwich panels. We are hoping to compare the empirical data received from this test to the FEA data acquired from simulations. There are a lot of failure modes that may occur, there is a whole code classification to them, as shown in the figure below.

 

 


Materials

 

Equipment required

  • Micrometers/Calipers

  • Compression fixture

  • Specimen Alignment Jig

  • Strain-Indicating Device

  • Bonded Resistance Strain Gauges

  • (Maybe Emery cloth)

  • Conditioning/Environmental test chamber

 

Procedures

This test involves compressing the test specimen in the following apparatus:

Figure 1: Compression Test Fixture (insert the one we actually used)

 

 

 

Test Specimen Prep

 

Only fill out if we actually do specimen preparation/ we change the standard geometries used in the ASTM document.

 


Raw Data

 

  • Results obtained directly from the test

Specimen Number

Compressive Force? (idk if this is it, on the ASTM summary it just says Force)

Compressive Strain? (I think this is it)

Ultimate Compressibe Strain?

Displacement (idk if we will actually measure this for this test)

We can continue with another table or just add cells to the end of this table?

 

  • Graphs below this with a description of what the graph is showing


 

Discussion

 

Here, we can just explain what went/think went wrong and how we could’ve maybe avoided it if anybody wants to read this for future reference?

 


 

Conclusion

 

  • Here, we can include our final remarks and what we learned while going through this test

  • Validity of results

  • Conclusions

  • Implications

  • Some Highlight of Results (quantitative statements)

  • Trends

  • More stuff that I can’t think of?
