摘要: 本文对六面进水的短切玻璃纤维增强聚砜(FR-PSu)和增强聚碳酸酯(FR-PC)的长方体试件的吸水性能进行了研究,认为它们的吸水方程与热传导方程相类似,可用三个薄型试件吸水方程相乘的公式来描述,而初期由于边界的影响仍符合Chi-hung Shen等推导的公式,从而可利用实验数据计算出单向的扩散系数及平衡含水量。Abstract: Water absorptior of the caboidal spccimens of chopped-glassfiber reinforced polysulfone (FR-PSu) and polycarbonate (FR-PC) in distilled water has been studied.Water absorptipon equation of the materials is similar to heat conduction equation.It is cepressed by a equation which is consisted of three water absorption equarions of one dimension specimen.At initeal stagd of water absorption it is coincident with Chi-hung Shen's equation.Therefore,the diffusivity and equilibrium water content can be deduced from the data.
