First, I would like to say that I am doing a science fair experiment testing the effectiveness of different polymers in absorbing hits. I have decided that I am looking to exert about 25 g-forces on each polymer. Average football hits are in the 50 g- force range, and taking everything into...
I am doing a science fair experiment testing the effectiveness of polymers commonly used in football helmets. I am planning on using polycarbonate and ABS, because they are commonly used. However, I am looking for one or two other polymers that are similar in strength and price to add more of...
