ISO 18608:2017标准是针对陶瓷复合材料的机械性能测试而制定的。陶瓷复合材料是由两种或两种以上的材料组成的,其中至少一种是陶瓷材料。这种材料具有高强度、高硬度、高耐磨性、高耐腐蚀性等特点,广泛应用于航空、航天、汽车、电子、医疗等领域。
在使用陶瓷复合材料时,裂纹扩展是一个重要的问题。因此,需要对陶瓷复合材料的裂纹扩展抗性进行测试。ISO 18608:2017标准规定了一种缺口敏感性测试方法,用于测定陶瓷复合材料的裂纹扩展抗性。
该测试方法需要使用标准试样,试样的几何形状和尺寸应符合标准要求。测试时,需要在试样上制造一个缺口,然后在试样上施加一定的载荷,观察裂纹扩展的情况。通过测量裂纹扩展的长度和载荷的大小,可以计算出陶瓷复合材料的裂纹扩展抗性。
ISO 18608:2017标准的实施可以帮助制造商和用户了解陶瓷复合材料的裂纹扩展抗性,从而更好地使用和设计这种材料。此外,该标准还可以为陶瓷复合材料的质量控制提供依据。
