1.1本试验方法包括以复合材料预浸料的重量百分比测定挥发物含量。本标准侧重于热固性树脂的复合材料，由于在加热过程中残留的水和挥发的低分子量基体成分的损失，加热时往往会损失几%的基体质量。 1.2本试验方法的使用仅限于循环空气烘箱的最高温度（约300 ° C） 。 1.3本试验方法的使用仅限于基体从钢筋中流出的温度。 1.4以国际单位制表示的数值应视为标准值。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 第8节给出了具体的预防说明。 ====意义和用途====== 本试验方法用于获得复合材料预浸料的挥发物含量。挥发物含量的知识有助于开发最佳制造工艺。 在暴露于标称固化或固结温度后测定挥发物含量。

1.1 This test method covers the determination of the volatiles content, in weight percent of composite material prepregs. This standard focuses on composites with thermosetting resins that tend to lose a few percent of the matrix mass when heated due to loss of both retained water and low molecular weight matrix constituents that volatilize during heating. 1.2 Use of this test method is limited to maximum temperature of circulating air ovens (approximately 300 ° C). 1.3 Use of this test method is limited to temperatures below which the matrix flows from the reinforcement. 1.4 The values stated in SI units are to be regarded as standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 8. ====== Significance And Use ====== This test method is used to obtain the volatiles content of composite material prepreg. Knowledge of the volatiles content is useful in developing optimum manufacturing processes. The volatiles content is determined after exposure to the nominal cure or consolidation temperature.
