火中聚合物基复合板结构的完整性设计

对火中聚合物基复合板在热和机械荷载组合下的受压承载力进行探讨。其典型案例是受火后横向温差下船体结构中板的状态。研究聚焦在横向温差和压缩机械荷载下的破坏模式。即由中心轴引起的弯曲、挠度和没有机械荷载的热变形。提出破坏模型的温度场和机械场并从设计角度对细节问题进行了探讨。对于设定的耐火时间,给出了设计机械荷载下的设计图;与此相对应,对于给定的机械荷载,设计了耐火时间。与传统的造船钢板不同,随温度变化的横向温差的设计过程包含多维破坏机理。

Designing Polymer Matrix Composite Panels for Structural Integrity in Fire

This paper discusses the compressive load bearing capability of polymer matrix composite panels in fire , a combined ther mal and mechanical loading condition . An example of such combinedloading conditionis that of panelsin ship structures under transverse ther mal gradients caused by fire .Investigation is focused on failure modes under transverse ther mal gradients and compressive mechanical loads , i .e .buckling ,deflection induced by the shift of the neutral axis ,ther mal distortion without mechanica...
