  • 有客户要求提供弯曲试验的Taylor's Modulus,请问Taylor's Modulus是什么东东?
    有没有相关测试标准?

    谢谢!

    From Google, I found that the term “Flexural Modulus (Taylor's)” appeared in several websites. It is likely that Taylor’s Modulus is Flexural Modulus (弯曲模量). If positive, relevant testing standards can be found by searching in Google with the key words “Flexural Modulus, GB” or “Flexural Modulus, ASTM”

    GB9341-1998《塑料弯曲性能试验方法》中关于弯曲模量的定义是:由负荷/挠度曲线的初始线性部分按Ef=L3P/(4bh3Y)计算。
    式中 Ef--弯曲模量,Mpa
    P --负荷-挠度曲线的初始线性部分上选定点的负荷,N
    Y --与负荷相对应的挠度,mm
    L --跨度,mm
    b --试样宽度,mm
    h--试样厚度,mm

    But improvement has been made in GB9341-2000. (新)

    For further details, please refer to新旧标准中塑料弯曲模量的计算方法比较 ( http://www.17-china.cn/Html/Cn/NewsView_ID13.html )
