Done By : School Name :Al-Shamal Independent Secondary school for Girls Composites : materials made from two or more constituent materials with significantly different physical or chemical properties, that when combined, produce a material with characteristics different from the individual components. Mobile Heater : This project will help to save time and effort and this product is easy to use and help in a variety of tasks like heating outside the home.

• Introduction
• Activity 1: Testing different kinds of ice.
• Activity 2: Hunting for composite materials.
• Activity 3: Testing materials for strength and
stiffness .
• Activity 4: Testing a foam composite for strength
and stiffness .
• Design Project : Design a Fishing pole.
• Product Idea : Mobile Heater

3. composite
• A composite material can be defined as a
mixture or combination of two or more visibly
Distinct materials.
• there's 3 types of composite materials :
Fiber-reinforced composite Particulate composite Laminar composite

4. Activity 1 :Testing different kinds of Ice
Objective : Comparing between ice and ice composite strength
Sample A Sample B Sample C
water
Water and
only
tissue paper
water and
many different
materials

5. Activity 1 :Testing different kinds of Ice
CONCLUSION:
It was the hardest one to
breakage
It was a little trickier to
break
The ice was easy breakage

6. Activity 2 :Hunting for composites
materials
Conclusion

7. Activity 3 :Testing materials for
strength&stiffness
We tested Different material sample :
steel rod
plastic rod
pasta
wooden rod
nylon rod
We test the strength by Appling load
We test the stiffness by bending

8. Activity 3 :Testing materials for
strength&stiffness
•Conclusion :
strength stiffness
Steel
Nylon rod
Wood
plastic
pasta

9. Activity 4 :Testing a foam composite for
strength and flexibility
objective : Testing a foam and foam composite

10. Activity 4 :Testing a foam composite for
strength and flexibility

11. Design Project : Designing a fishing Pole
• Objective : make a fishing rod by a certain measure.
1-flexible 2-strong 3-Light

12. Design Project : Designing a fishing Pole
we have made our
fishing Pole by the
simple materials
according to the rules
then we test it .
Result :The fishing pole has to
be thick where the tensile
force is applied, and it has to
be thin and flexible from end
so it can catch fish without
breaking.

14. Mobile Heater
* This project will help to save time and effort and this product is easy to use and
help the Qatari society in a variety of tasks like heating outside the home.
* Which attracted us to this project because of the difficulty in heating foods outside
the home, and the characteristics of the project it easy to navigate in addition to
that, a multi-sizes, has a promising future because it is used in flight
* Scientific background that we used are chemical exothermic reactions, and we
have benefited from Albairaq activities that article useless can make it even more
important.
* The primary goal of our project is to save time and effort and use this project in
several areas.

We used calcium chloride as it is less risky and cheap
Material

17. Recommendations:
oThis product can be developed in terms of size and
temperature.
oWe have encountered a problem in search for
repellents to heat and we know that calcium chloride
and sodium hydroxide repellent materials to heat and
we compare them and concluded that sodium
hydroxide that is very high temperature, but using
sodium hydroxide is dangerous with food either
calcium chloride temperature degree sufficient to heat
the food and safe .

18. conclusions
Composite are too helpful for our general life
and it help us in a lot of things even if we can’t
see it, we learned many things in the
workshop 4 days and we hope we can help our
country by creating new .

19. Acknowledgment
We would like to thank all people, teachers,
friends, and our school that supported us
during our journey in AL-Bairaq.
Also we like to thank AL-Bairaq team and the
sponsors who gave us the opportunity to
participate in AL-Bairaq project, create and
innovate.
