Abstract

This study evaluates the influence of a thermal treatment of a basalt fiber on capillary wicking tests and in-plane permeability experiments, under several pressure differences. The impact of the treatment was characterized at three scales: microscopic, to determine the fiber surface energy; mesoscopic, to estimate an equivalent capillary pressure (

P_{c a p}

) of the fabric in spontaneous impregnation; and macroscopic, to determine the saturated (

K_{s a t}

) and unsaturated (

K_{u n s a t}

) permeability of the fibrous preform at the process scale. Results at the microscopic scale showed that the thermal treatment increased the polarity of the fiber by 22% and decreased its surface roughness. Capillary wicking tests showed that the treated fabric presents a better affinity with water, increasing

P_{c a p}

by 68%. At the process scale, permeability experiments showed the increase of

K_{s a t}

and

K_{u n s a t}

after treatment. Finally, results of capillary pressure (

Δ P_{γ}

) showed a dominance of capillary effects under the negative pressure difference.

玄武岩纤维表面能对毛细管吸水和加固材料面内渗透性的影响

本研究评估了玄武岩纤维热处理对毛细管吸水试验和几种压力差下平面渗透性实验的影响。热处理的影响体现在三个方面：微观方面，确定纤维的表面能；中观方面，估算织物在自发浸渍过程中的等效毛细管压力（Pcap）；宏观方面，确定纤维预型件在加工过程中的饱和渗透率（Ksat）和非饱和渗透率（Kunsat）。微观结果显示，热处理使纤维的极性增加了 22%，并降低了其表面粗糙度。毛细管吸水测试表明，经过处理的织物与水的亲和性更好，Pcap 增加了 68%。在工艺尺度上，渗透性实验表明，经过处理后，Ksat 和 Kunsat 都有所增加。最后，毛细管压力（ΔPγ）结果表明，在负压差条件下，毛细管效应占主导地位。
