本文介绍了一种新的先进复合材料弯曲试验方法。虽然传统的三点或四点弯曲试验可以方便地获得弯曲强度和模量，但它有几个缺点，特别是对于先进的复合材料。一种新提出的方法是基于通过轴向压缩弯曲，这种方法克服了上述缺点。设计并加工了一套试验装置，对几种复合材料进行了试验。除了弯曲强度，还开发了弯曲模量的评估方法。结果表明，该方法特别适用于T800/环氧石墨复合材料等高性能复合材料。
This paper deals with a new bending test method for advanced composites. Although a conventional three- or four-point bending test is convenient to obtain bending strength and modulus, it has several disadvantages especially for advanced composites. A newly proposed method is based on a bending by means of axial compression and this method overcomes the above disadvantages. A set of testing device was designed and machined and several kinds of composites were tested. In addition to the bending strength, the method to evaluate the bending modulus was also developed. It has been made clear that the new method is suitable especially for high performance composites such as T800/epoxy graphite composites.
