I What absorbs impact better, hard plastic or silicon?

  1. Feb 12, 2017 #1
    Hello,

    Not sure really where to ask this but I couldn't find a good answer so why not a physics forum, because well this involves physics. I just got a gopro for my fpv drone and I am wondering what type of case to get for it, either a plastic or silicone one. If im going 30+ mph and smack into a tree what would absorb most of that energy and protect the gopro?

    Thanks

    silicon- absorbs shock better
    if you use plastic it will most likely crack depending on how hard it is

    wonder where you got that info from ?
    the silicon I see in semiconductors is very brittle
    and I have no idea where you would get sufficient quantities from to encase a gopro ???

    maybe you would be much better looking at Styrofoam or foam rubber

    when he said silicon I was assuming a sort of malleable silicon case that is commonly seen in phone cases, not conductor silicon - however I see your point and foam rubber sounds feasible

    most mobile phone cases are plastics of one type or another, polycarbonate etc

    There are both plastics and silicone based materials that could be used as a shock absorber.
    With plastics you have more choice and they are cheaper.

    It's not just about the material, but the specific design:
    - How the camera is mounted inside the hard box
    - How thick the silicon is
    - The mechanical weak points of the camera
