标准摘要
[中文适用范围]： 表观挥发物含量是加热时损失的物质相对于初始质量的百分比。 该方法的原理是通过测量试样在通风烘箱中以一定温度加热时的质量变化来获得。 指定的温度和指定的时间长度。 该方法适用于所有单向和多向纤维增强预浸料以及所有热固性树脂基体。 不适用于未浸渍的增强纤维。 [外文原描述]： The apparent volatile-matter content is the percentage of matter lost on heating, relative to the initial mass, The principle of the method specified is obtaining it by measuring the change in mass of a test specimen when heated in an air-ventilated oven at a specified temperature for a specified length of time. The method is applicable to all unidirectional and multidirectional fibre-reinforced prepregs and all thermosetting-resin matrices. Does not apply to unimpregnated reinforcement fibres.
