Improved Key Cards. By Logan Eddy, Jeffrey S. Hammond and Marcus Walters. SNAP!!. Research Question. Which key will withstand more stress, the newer composites fiberglass or the older plastic? We used four tests to determine this: Laundry Test Three-Point Bending Test Hot/Cold Test

Select composite materials and prep tool
Calculate and mix resin and hardening agent
Mix resin mixture with fiberglass
Make bag for composites
Leave out to cure for at least 24 hours
Cut out and sand keys
Test new composite keys
We sent a key through the laundry to find out how it would hold up, and if it would still be in usable condition.
To simulate weather conditions in either Winter or Summer, we are going to freeze the cards and bend them. As well as heating them up in hot water and bending them.
A test in which the edges of the card are held and pressure is added to the center to see how much the key can bend before it breaks.
The torsion test will show how durable the side strengths are and to simulate your card being put in your pocket long ways to bend it around your hip. The torsion test is just another test used to identify the flexibility and durability of a key in a different manner.
Our keys work as actual keys, but they aren’t any better than the keys already in use.
This project helped us to learn about new and different possibilities that could be used in future testing.
Other things we would like to test are:
Different materials for the keys such as:
-Kevlar (Impact Resistance)
