一、前言高分子材料抵抗其它较硬物体压入的性能称为高分子材料的硬度。硬度数值大小不仅表示高分子材料的软硬程度,而且还与磨耗和抗拉强度等力学性能有一定的关系。测量塑料硬度应用较广泛的方法是巴柯尔硬度。巴柯尔硬度是一种压痕硬度,它以特定压头在标准弹簧的压力作用下压入试样,以压入的深度来表征试样的硬度。巴柯尔硬度作为玻璃钢制品的一个工艺指标日益受到重视。英、美等国已把巴柯尔硬度正式列为检查玻璃钢制品质量的一个重要指标。目前许多工作证明,巴柯尔硬 First, the introduction of polymer materials to resist the performance of other hard objects pressed into the polymer material known as the hardness. The hardness value not only represents the degree of soft and hard polymer materials, but also with wear and tensile strength and other mechanical properties have a certain relationship. The most widely used method of measuring plastic hardness is the Barcol hardness. Barcol hardness is a kind of indentation hardness, which is pressed into the specimen under the pressure of a standard spring with a specific indenter, and the hardness of the specimen is characterized by the depth of penetration. Barcol hardness as a glass fiber reinforced plastic products more and more attention to an indicator. Britain, the United States and other countries have formally listed Barcol hardness as an important indicator of the quality of FRP products. Much work has so far proved that Bakr is hard
