Fire resistance testing of components made of carbon fibre reinforced polymers (CFRP) usually demands intermediate-scale or full-scale testing. A bench-scale test is presented as a practicable and efficient method to assess how different fire protective systems improve the structural integrity of CFRPs during fire. The direct flame of a fully developed fire was applied to one side of the CFRP specimen, which was simultaneously loaded with compressive force. Three different approaches (film, non-woven, and coatings) were applied: paper with a thickness in the range of μm consisting of cellulose nanofibre (CNF)/clay nanocomposite, nonwoven mats with thickness in the range of cm and intumescent coatings with a thickness in the range of mm. The uncoated specimen failed after just 17 s. Protection by these systems provides fire stability, as they multiply the time to failure by as much as up to 43 times. The reduced heating rates of the protected specimens demonstrate the reduced heat penetration, indicating the coatings’ excellent heat shielding properties. Bench-scale fire stability testing is shown to be suitable tool to identify, compare and assess different approaches to fire protection.

由碳纤维增强聚合物 (CFRP) 制成的部件的耐火测试通常需要进行中等规模或全面的测试。台架试验作为一种实用且有效的方法来评估不同的防火系统如何在火灾期间改善 CFRP 的结构完整性。将完全发展的火焰的直接火焰施加到 CFRP 试样的一侧，同时加载压缩力。应用了三种不同的方法（薄膜、无纺布和涂层）：由纤维素纳米纤维 (CNF)/粘土纳米复合材料组成的厚度在 μm 范围内的纸、厚度在 cm 范围内的无纺垫和具有厚度在毫米范围内。未涂层试样仅在 17 秒后失效。这些系统的保护提供了防火稳定性，因为它们将故障时间增加了多达 43 倍。受保护样品的加热速率降低表明热渗透降低，表明涂层具有出色的隔热性能。实验室规模的防火稳定性测试被证明是识别、比较和评估不同防火方法的合适工具。
