摘要
用测定树脂砂弯曲载荷-挠度曲线的方法,测定树脂砂中加入附加物后的断裂功,分析了附加物对树脂砂的增韧作用.
The frature work of the resin sand with additions was determined by a new method determining bend load-deflexion curve of the resin sand. The toughening effect of several additions on the cold-setting resin sand has been systematically investigated.
