This proposal involves mathematical modelling of the burning and degradation of mechanical properties of flame retadant glass fibre reinforced plastic laminates. At Bolton, novel flame - retardant laminates have been developed and patented during an earlier EPSRC project. These laminates contain novel flame retardant chemicals and inherently flame retardant cellulosic fibres as additives in the resin matrix or as additional fabric layer. Some laminates also contain polymer layered silicate nanocomposites with or without conventional flame retardants. The laminates show improved flame reatrdant and residual mechanical properties after fire/heat exposure compared to unmodified laminates. This proposal is a joint attempt by 'Fire and Heat Resistant Materials' group at Bolton Institute and 'Fire Engineering Research Group' at University of Manchester to numerically predict their burning and mechanical behaviour under a fire condition. The Bolton team will focus on the burning aspect and the Manchester team the burning induced degradation of mechanical properties. Results from the Bolton team will provide input of material damage and temperature information to the Manchester team so that the outcome of this project will be an integrated predictive model for combining both burning and burning-induced mechanical behaviour. A limited amount of mechanical tests at elevated temperatures will be carried out to provide data for validation of the numerical models developed.

本方案涉及阻燃玻璃纤维增强塑料层压板的燃烧和机械性能退化的数学模型。在博尔顿，新型阻燃层压板在早期的EPSRC项目中被开发并获得专利。这些层压板含有新型阻燃化学品和固有阻燃纤维素纤维，作为树脂基体的添加剂或作为额外的织物层。一些层压板还含有含有或不含常规阻燃剂的聚合物层状硅酸盐纳米复合材料。与未改性的层压板相比，层压板在火/热暴露后表现出更好的阻燃性和残余机械性能。该提案是由博尔顿研究所的“防火和耐热材料”小组和曼彻斯特大学的“消防工程研究小组”共同尝试的，旨在数值预测它们在火灾条件下的燃烧和机械行为。博尔顿队将专注于燃烧方面，而曼彻斯特队将专注于燃烧引起的机械性能退化。博尔顿团队的结果将为曼彻斯特团队提供材料损伤和温度信息的输入，以便该项目的结果将是一个综合的预测模型，将燃烧和燃烧引起的机械行为结合起来。将在高温下进行数量有限的机械试验，为所开发的数值模型的验证提供数据。
