Introduction

Testing what material is the best for a football boot My objective is to find out which material is the best to use for a football boot. To do this various test were done to see which material would be best. These tests were durability, friction/grip, strength and waterproof. Durability Introduction Durability is one the main properties for a football boot as with good durability it means the shoe will last longer and won't wear down easily. A test was done to see which material has the best durability. Hypothesis I think that rubber will have the best durability while I think sponge will do the worst in the durability test. Apparatus * Materials(sponge, leather, foam, rubber and fabric) * Sandpaper Method The apparatus was set up as instructed. To the test for durability sandpaper would be rubbed against each material. To make it a fair test each material would be rubbed with the sandpaper and they would be rubbed the same amount of times (20times). ...read more.

After that 100g weights were added each time. To make it a fair test each material would have 5 100g weights used. Results Results Weight (100g) Grip Fabric 500g 4N Sponge 500g 4N Foam 500g 2N Leather 500g 3N Rubber 500g 5N Conclusion The results show that foam has the worst grip and like I predicted rubber has the best grip. Rubber has the best grip because it is a material that can stretch far. Strength Introduction It is important for a football boot to have good strength so the boot doesn't break easily and so the footballer can have more power on his shot. So a test was conducted to see which material has the best strength. Hypothesis I think that leather will have the best strength. While I think sponge will have the worst strength. Apparatus * Materials (sponge, leather, foam, rubber and fabric) * 100g weights * Clamp stand * Crocodile Clip Method The apparatus was set up as instructed. To test the strength of the materials each material would be attached to the clamp stand and 100g weights were added one at a time to see what happened to the material. ...read more.

Conclusion

While I think leather will be the best to use for a waterproof shoe as I think it will stop the water going through. Apparatus * Materials(sponge, leather, foam, rubber and fabric) * 6 Beakers * Pipette * Water Method The apparatus was set up as instructed with each of the five materials over the beakers. While by using the pipette drops of water were put onto each of the materials and were left to see what happened. To make it a fair test each material got the same amount of drops (10 drops) and were left for the same amount of time (5 minutes). Results Material Time left for Drops What Happened Sponge 5 minutes 10 Soaks Though Leather 5 minutes 10 Doesn't Soak Through Foam 5 minutes 10 Soaks Through Rubber 5 minutes 10 Doesn't Soak Through Fabric 5 minutes 10 Soaks Through Conclusion From looking at the results it is possible to conclude that the worst materials to use for waterproof are sponge, foam and fabric while the best to use would be leather and rubber. ?? ?? ?? ??
