本文是第三个系列的防火夹层玻璃复合材料含有一个膨胀硅酸盐中间层和增强纤维的硅酸盐基体的膨胀行为的影响进行了研究。两种硅酸盐基质与不同的二氧化硅/金属氧化物的比例（SiO2：Na 2 O）增强聚丙烯（PP），聚酰胺66（PA 66），AR-玻璃（ARG）和不锈钢（ST）纤维，选择，因为它们的碱和UVA的耐性能。检查具有5/95和10/100质量比的纤维/硅酸盐混合物的热降解行为，以了解每种纤维类型对每种硅酸盐的膨胀的影响。硅酸盐层的纤维增强物作为非织造网或作为织造网。通过在450 °C的炉中加热复合材料5分钟并测量膨胀层厚度来研究硅酸盐的膨胀性质。结果表明，非织造网增强材料中的所有纤维类型都有负面影响，而织造网形式的无机玻璃纤维对硅酸盐基质的整体膨胀的影响可以忽略不计。提出了纤维类型是次要的，而织物结构在抑制膨胀方面起着重要作用。优选的增强件应当优选地具有开放的网状特征。
This paper is the third in series on fire-resistant laminated glass composites containing an intumescent silicate interlayer and studies the effect of reinforcing fibres on the intumescent behaviour of the silicate matrices. Two silicate matrices with different silica/metal oxide ratios (SiO2:Na2O) were reinforced by polypropylene (PP), polyamide 66 (PA66), AR-glass (ARG) and stainless steel (ST) fibres, selected because of their alkali and UVA resistant properties. Thermal degradative behaviour of fibre/silicate mixtures having 5/95 and 10/100 mass ratios were examined to understand the effect of each fibre type on the intumescence of each silicate. Fibre reinforcements of the silicate layer were either as a nonwoven web or as a woven mesh. The intumescent properties of silicates were studied by heating the composites in a furnace at 450 °C for five minutes and measuring the intumescent layer thickness. The results showed that all fibre types in nonwoven web reinforcements had a negative effect while inorganic glass fibre in a woven mesh form had a negligible effect on the overall intumescence of silicate matrices. It was proposed that while fibre type was of minor importance, the fabric structure played an important role in inhibiting intumescence. Preferred reinforcement should preferably have open mesh-like characteristics.
