Things like Badminton rackets, Tennis rackets, golf clubs, softball bats and hockey sticks. I know its light and all but what are the other reasons why is it used as a stick to hit objects? Can someone give me a detailed answer? Edit: Is tensile strength an important factor to making these sticks if so why?
In: Engineering
Concrete is very strong in compression, but only worth 10% of it’s strength in tension. That’s why it’s easy to bust a chunk of concrete, because when you bend it, you compress one face and stretch the other.
That’s why we put steel in Concrete. It has a really high tensile strength, and prevents the block of concrete from pulling apart, making it super strong. But steel and concrete are really heavy. Steel is strong, but not really all that strong when you break it down to thicknesses measured in micro-millimeters.
Carbon Fiber on the other hand is CRAZY strong. But it’s also really thin, so it behaves more like rope or string. Great in tension, but not good for pushing on.
So, you surround the Carbon Fiber in something flowable and rigid like Concrete. In sports equipment, that’s usually some kind of plastic epoxy thing that can be engineered with exact hardness vs bendiness specifications. The Carbon Fiber will make sure it never breaks or cracks, and will fit whatever form you put it in.
