Aerospace Materials
We built composite 4-ply and sandwich samples, using uni-directional and bi-directional fiberglass.
Each group should create a wiki page to address the following:
- List the step-by-step procedures you followed.
- Highlight important safety procedures followed while working with composites.
- Identify the differences in wetting out uni- and BID fiberglass. Present a hypothesis as to why these differences exist.
- List the physical characteristics of your finished samples. Include:
- size - length, width, height
- weight - weight before finishing, finished weight, weight of uni plies, weight of bi-plies, weight of foam piece
- quality of construction - air bubbles?, delamination? voids?
- any other physical characteristics of your sample
- Judge your fabrication technique by including data on the weight differences of samples. Provide suggestions for improvement of your technique.
- What impacts would using your original fabrication technique have on an actual airplane? What would a manufacturer do to mitigate these impacts?
- Were your second day results better than the first day of construction? Why?
- Propose a step-by-step procedure that eliminates (or tries to eliminate) the problems discussed above.
- Compare your samples to other group's samples.
- Formulate a plan for using both uni- and BID fiberglass on an airplane. Give specific uses for both.
