Strength and Stiffness • Activity 4: Testing a Foam Composite for
Strength and Stiffness • Design Project: Designing a Fishing Pole• Product Idea
Introduction
• A composite material is made by combining two or more materials to give the composite unique properties. Composites do not dissolve or blend into each other.
Activity 1: Testing Different kind of Ice
• Objectives – Testing 3 samples of ice composites• Water only• Water and tissue paper • Water , cotton , newspaper and straws
Results
• We found that the composite made of ice, cotton , straw and newspaper was stronger than ice alone
Activity 2: Hunting for Composites
• Objectives – We conducted an internet study to know more
about composites.
Composites Types Properties Examples Particle composites Stronger , cheaper concrete
Laminar composites
Flexible, light weight
plywood
Reinforced composites
Lighter, stronger and stiff material
Material used in tennis racquet
Activity 3: Exploring the Difference Between Strength and Stiffness
• Objectives – Test different materials like pasta , iron , nylon ,
wood , plastic.– Predict the ranking of the above materials for
strength and stiffness.
ResultsMaterial to be tested
Prediction about strength
Prediction about stiffness
Ranking from strongest to weakest
Ranking from stiffest to flexible
Iron rod 1 2 1 2
nylon 2 3 2 5
plastic 4 4 3 4
Wood 3 5 4 3
pasta 5 1 5 1
Activity 4: Testing Foam Composite for Strength and Stiffness
• Objectives – Test 3 types of foam• Plain foam• Foam reinforced from one side • Foam reinforced from two sides
ResultsMass (g) Deflection in Plain
foam(cm)Deflection in 2-side foam(cm)
Deflection in 1-side foam(cm)
0 0 0 0
100 0.2 0 0.6
200 0.5 0.4 1.2
300 0.7 0.8 1.8
400 1.3 1.3 2
500 1.9 1.7 2.4
600 3 2 2.7
Conclusion
• We found that 2- side foam reinforcement showed high property of strength and stiffness.
• It showed less deflection for higher mass.
Design Project: Designing a Fishing Pole
• Objectives :– Design a fishing pole, made out of a composite
material that is based on plastic straw.

1000 22.5 9.5
Conclusion
• We used plastic straw ,wood ,paper , cotton and wire as composite to make fishing pole to make it more flexible and strong which are the characteristics of fishing poles
• Hence more weight could be handled using composite material.
Heat resistant car cover
• Owing to the high temperature in our country, we decided to make use of composite material in manufacturing car covers.
• We use the following material in composites:– Fabric– Nylon– Helium– Normal cover
Conclusion
• Applications and Advantages– Our project helps people to reduce accidents
caused by overheating in cars during summer.– Also it cautions other drivers when parked at night
due to its fluorescent property.– Our design is highly economical , and
environmental friendly.
