摘要

在万能试验机(UTM)中对织物加固材料进行压实,可以确定在较大压力范围内可实现的纤维体积分数,这对复合材料制造来说是非常有价值的信息。从第一个国际压缩性基准中可以看出,织物叠层厚度测量的不准确性、顺应性校正方法以及压实板之间的不平行导致压缩曲线非常不准确。本文介绍了影响基于机器位移的间接厚度测量方法和使用激光传感器的直接测量方法的不同变异源,并估算了其对精度的影响。总之,两种厚度测量方法得出的结果相似;但是,直接方法测量的厚度由于钻机位移或板块间方向的微小变化,再加上外部干扰或压实板振动等其他变化源,导致整个测试过程中的测量精度变化较大。

Achieving highly accurate cavity thickness measurements in fabric compaction
The compaction of a fabric reinforcement in a Universal Testing Machine (UTM) allows to determine the achievable fiber volume fraction across a wide range of pressures, a valuable information for composite manufacturing. As seen in the first international compressibility benchmark, inaccuracies in the fabric stack thickness measurement, the approach to compliance correction and the non-parallelism between compaction plates resulted in highly inaccurate compression curves. In this paper, the different variability sources affecting indirect thickness methods, based on the machine displacement, and direct methods with laser sensors are presented and its impact on the accuracy is estimated. In conclusion, both thickness measurement methods produced similar results; however, the thickness measured by direct methods experienced more variability due to minor changes in the rig’s displacement or the orientations between plates, combined with other sources of variability such as external interferences or vibrations from the compaction plate which led to variations in measurement precision throughout the tests.
