Composite materials
This Laboratory exercise has an experimental procedure and is used to instil the procedures and techniques used when manufacturing laminates and composite materials. From this lab, the feel confident of understanding the theory they should use in fabricating a stable composite laminate, and what properties they should look for in the development of composite materials.
When writing your report the following needs to be addressed:
1. The theory behind the layered composite using symmetric code.
2. Fabrication procedures of composites.
3. Graph GFRP composite results using raw data files and construct the true
stress-strain curves.
4. Calculate Young’s Modulus (E) for each material and compare experimental
values with literature values.
5. Discuss any differences in mechanical behaviour between the two samples
with different layers sequence.
6. Analyse the fracture modes of each sample (ductile fracture, brittle fracture,
or intermediate fracture mode).
7. Explain any unexpected results.
Specific Criteria
• Report writing and Presentation:
– produce technical report with clear writing style.
– present experimental results in the form of graphs.
• Analysis of the results:
– extract useful information from the graphs.
– Compare the results of two specimens and discuss the results.
• Discussion:
– -interpret the results and deduce any trend or observable physical phenomenon.
– demonstrate understanding of the experiment.
– -pinpoint any experimental error.
– -compare your results.
– -draw technical conclusions.

Conclusions
The conclusions should be presented in a clear and concise manner and should relate to the purpose for which the work was undertaken.
Recommendations
The recommendations are specific suggestions for future work that may be undertaken as a direct consequence of the work done. As with the conclusions, these should be presented in a clear and concise manner.
SECOND REPORT, only ((Conclusion))
Wind Tunnel Testing of a Model Wing
The aim of the experiment is to determine the lift, drag and pitching moment characteristics of a wing (NACA 23012 aerofoil) by varying the angle of incidence at constant wind speed under two-dimensional wind flow conditions and to study the variation with speed of the lift coefficient for a fixed incidence.
Specific Criteria
• Report writing and Presentation:
– Produce technical report with clear writing style.
– Present experimental results in the form of graphs.
– Find the best-fit curves
• Analysis of the results:
– Convert forces and moment into coefficients.
– Extract useful information from the graphs.
• Discussion:
– Interpret the results and deduce any trend or observable physical phenomenon.
– Demonstrate understanding of the experiment.
– Pinpoint any experimental error.
– Compare your results with Abbott and Doenhof.
– Draw technical conclusions.
