Abstract

Various cured binding agent specimens are investigated in order to determine principles of variation of microhardness values of matrix along their thickness. Microhardness measurements of cured binding agent are carried out on cross sections at the load on indenter of microhardness meter of 10 g (0.1 N). The studies show that the microhardness value of the plastic along the thickness of the specimens from the front surface of the specimen to its rear side changes according to a parabolic law with critical microhardness values in the core of the cross section of the semifinished product and direction of the parabolic curve is determined by the type of binder.

本体聚合物复合材料基体特性变化的评价方法

摘要

为了确定基质的显微硬度值沿其厚度变化的原理，对各种固化的粘合剂样品进行了研究。固化粘合剂的显微硬度测量是在显微硬度计压头压头上的载荷为10 g（0.1 N）的情况下进行的。研究表明，从试样的前表面到背面，沿着试样厚度的塑料的显微硬度值根据抛物线规律变化，在半成品横截面的中心和方向上具有临界显微硬度值。抛物线的角度取决于结合剂的类型。
