玻璃钢的吸水值,无论从绝对量角度还是从相对量角度来看,都与试件大小有关。本文从实测和模型计算两个方面探索了吸水量和试件大小的关系,二者所得结果相当吻合。分析表明,当试件尺寸增大时,虽然绝对吸水量会无限增加,但以重量百分率和单位面积吸水量表示的相对吸水量会趋向各自的极限确定值。
Fiberglass water absorption value, both from the absolute point of view or from the relative point of view, are related to the size of the specimen. This paper explores the relationship between the amount of water absorbed and the size of the specimen from both the actual measurement and the model calculation, and the results obtained by the two are in good agreement. The analysis shows that when the specimen size increases, although the absolute water absorption increases indefinitely, the relative water absorption expressed by weight percentage and water absorption per unit area tends to the respective limit determination value.
