Future Experiments
Due to time constraints, we were unable to perform all the tests we wished to on our samples. Should we be given the opportunity to further work on our project, we would conduct the following tests to give a better representation of the physical properties of our material.
Additional tests:
- Compression strength
Using the testing machine at the FoodTech lab at BCIT, we will perform compression strength tests on our samples to determine its maximum withstandable load strength from parallel sides, the percent deformation at various loads, and the compression modulus.
- Water resistance
A repeat of the flexural strength test after samples have been immersed in room temperature water for a period of 10.0 minutes.
- Heat resistance
A repeat of the flexural strength test after samples have been heated to 50 degrees C.
- UV Photodegradation
Procedure:- Cut out 1.0cm2 samples of each kind of fibre reinforced plastic. Measure the mass and volume.
- Place each sample under a UV lamp.
- After every 48 hour interval, remove remaining sample from UV lamp and measure again the mass and volume (through indirect measurement of water displacement) to determine the percentage decrease in mass and volume.
- Dry sample and place again until UV lamp.
- Continue until sample has been under the UV lamp for 240 hours (10 days) or no visible plastic remains.
We will plot volume and mass data on a- volume vs. time and
- mass vs. time graph, respectively, and extrapolate to determine i) rate of degradation and ii) total degradation time.
