Composites, Combrella (Composites- Umbrella), IDM8
The document discusses the exploration of composite materials by a group of students from Al-Wakra Secondary School for Girls, focusing on their properties, applications, and strength testing. It highlights various activities conducted to illustrate the differences between composite and pure materials, culminating in a design project for a multifunctional umbrella to protect against Qatar's harsh weather. The students express gratitude to their teachers and sponsors for their support throughout the project.

- 5. The next daywe took the ice from the fridge then we remove the composites & the water ice from the container . After that , we put it in the same level in 50 cm , then we dropped it in the floor to see anyone of them was more strong composites We conclude that the composites material stronger than pure material , because we dropped the composites material 3 times in the floor to disintegrate opposite than the pure material that disintegrate in the first drop .

- 18. Conclusion: The two sidefoam was the strongest foam cause it was covered from up and down so its protected the foam from breaking.
- 19. Design Project: Designfishing pole It has to be: STRONG FLEXIABLE REINFORCED
- 20. Project Design: Designinga Fishing Pole Hold at least 200 gm without failure. Deflect at least 2 cm with 200gm. Largest load hold/pole mass.
- 21. Project Design: Designinga Fishing Pole We designed two different simple of fishing pole , we use some material to make the pole more flexibly , strong & reinforced .
- 22. Project Design: Designinga Fishing Pole We but the fishing pole in the scale to measure and to see did the fishing pole have a flexibly , strong & reinforced ?? then we use some weights to see if the pole will come to normal or will break ! The fishing pole we were did it , it contains flexible , strength & reinforced , because we but different types of weights , then it came to her normal , and it didn’t break , it’s a good composites .

- 24. Final project: Our projectname is ? Composite + umbrella our project is talking about covering all the houses that is being built or the gardens, coffee shops, that are already built outdoors
- 25. The project’s explanation Umbrellais made of several materials to help cool place in the summer and heating in winter
- 26. The importance ofour project. 1-The project will definitely be useful for Qatar’s hot weather 2- Outdoors places will be protected because it will prevent the sunshine from passing through. 3- The construction workers will no longer struggle with tiredness and exhaustion because this project will warm them up from the heat. 4- People will have the chance to keep their skins natural and protected.
- 27. The advantages ofour project 1-Protect people with skin disease category and get away from all that would be bad for them from the atmosphere 2-Encourage construction workers to finish their work on time 3-Good to go outside at all times and rituals Airborne
- 28. Facing any obstaclesin the project. 1-People are not exposed to sunlight, leading to the loss of vitamin D is necessary for the body 2-Increasing the quantity of injury to a variety of diseases because many scientists who say that the exposure to the sun an important factor in strengthening the immune system
- 29. We hope This projectis going to be spread in Qatar and the whole world as well. We hope that our project be the first, we wish we could be one of the winners Conclusions
- 30. The benefits ofAL-Bairaq 1-We gained a ton of information that will help us to improve our general knowledge. 2-We have learned how to mix materials together, and how to choose them, and know how to distinguish between vehicles. 3-Now we have an idea of how to make a good and useful and valid compound for use of our environment.
- 31. Acknowledgment Many thanks tomy teachers, school and AL-Bairaq team from Center for Advanced Materials (CAM), Qatar University for supporting us during our journey with a AL- Bairaq. Also, we would like to thank the sponsors .
