    Can someone tell me what is the difference.

    Because I saw "Yang Yang" badminton racquet have this type of material.:confused:

    Material Properties

    Louis,
    Hope this help !

    First of all, pure titanium is too soft and can not be used in badminton, most of said titanium is alloy of other material like Aluminum, vanadium, like (famous strength material Ti-3Al-2.5V ) etc

    The mesh is only on outer layer of graphite. If you grinding it out, inside still is graphite material. pull the titanium string mesh out weighting against total weight. The weiigh ratio is less than 1 % of total weight. What is the titanium for racquet again?

    Material property
    at same weight, graphite is st 200% more efficient than titanium

    Titanium stiffness (young's modulus) is 27,000,000 psi density of 0.16257 lb/in^3, while normal graphite is 26,251,830 ps density 0.057803
    efficiency modulus/weight , for titanium is 1.660, graphite is 4.541,


    By the way, All the information is readily available at web or any engineering handbook




    :eek:
    Please refer the information to web

    or Mark's Standard handbook



    Louis, I Hope it help

    Woven = weave of carbon fiber.
    HiM graphite is just graphite that is stiffer than usual.

    They are all variants of graphite, and not necessary exclusive. I have a racquet that claims to use hi modulous grapite, and it weaves the fibers on the shaft and head.,
