为了研究在建筑物的地板中使用GFRP拉挤型材作为结构元件的可行性，进行了实验调查，以分析其暴露于火灾时的行为。特别是，使用不同的保护涂层/层（膨胀型涂层，蛭石/水泥基砂浆和硅酸钙板），以提供防火玻璃钢拉挤型材的可行性和有效性进行了研究。先前的实验表明，上述被动防火系统允许满足所设想的应用的耐火性要求。本文介绍了有关这些解决方案的火灾反应要求的履行调查的结果。实验方案包括对GFRP和防火材料的动态力学分析（DMA）和热重/差示扫描量热法（TGA/DSC）实验。随后，使用锥形量热仪对玻璃钢拉挤层压板进行了火灾反应测试，包括未保护的和用不同防火系统保护的。根据建筑规范要求，这些实验的结果允许定义每个研究解决方案的应用领域。(C)2009爱思唯尔有限公司保留所有权利。
In order to study the viability of using GFRP pultruded profiles in floors of buildings, as structural elements, experimental investigations were carried out to analyse their behaviour when exposed to fire. In particular, the feasibility and efficacy of using different protective coatings/layers (an intumescent coating, a vermiculite/perlite cement based mortar and a calcium silicate board) to provide fire protection to GFRP pultruded profiles was investigated. Previous experiments showed that the above mentioned passive fire protection systems allow fulfilling fire resistance requirements for the envisaged application. This paper presents the results of the investigations concerning the fulfilment of the fire reaction requirements of those solutions. The experimental programme included dynamic mechanical analyses (DMA) and thermogravimetric and differential scanning calorimetry (TGA/DSC) experiments on both the GFRP and the fire protection materials. Subsequently, fire reaction tests were carried out on GFRP pultruded laminates, both unprotected and protected with the different fire protection systems, using a cone calorimeter. Results of these experiments allowed defining the field of application of each investigated solution, according to building code requirements. (C) 2009 Elsevier Ltd. All rights reserved.
