摘要：通过加入 4-5 份纳米分散粘土，炭黑填充的 SBR 的弯曲疲劳寿命得到显着提高。粘土的添加并没有降低复合材料的交联度，但提高了滞后性和撕裂能。弯曲断裂形态的 ESEM 观察表明，纳米分散粘土层比炭黑具有优势，因为它们可以钝化裂纹。粘土用量对复合材料弯曲疲劳寿命的影响。
Summary: The flex-fatigue life of carbon-black-filled SBR was dramatically improved by incorporation of 4–5 phr nanodispersed clay. Addition of clay did not decrease the degree of crosslinking of the composite but improved the hysteresis and tearing energy. ESEM observation of the flexing-fracture morphology indicated that nanodispersed clay layers had the advantage over carbon black in that they could blunt the crack. Effect of the clay amount on the flex fatigue life of the composites.
