Abstract
The main objective of the present study was to develop a fire thermal model able to predict the evolution of the temperature and decomposition gradient across a laminated composite structure when exposed to fire. The thermal response of composite laminate made of organic polymer matrix was investigated under severe temperature conditions as samples were exposed to high temperatures up to 750 °C. The highlight is that a behavior law for water is included in our thermo-mechanical model to estimate effects due to a moisture content field on the thermal response of composite laminates. In particular, porosity and gas pressure are strongly influenced by the presence of water in the material and modify the thermal behavior accordingly. This enabled us to propose a new approach that can be used for the prediction of hygro-thermo-chemico-mechanical post-combustion properties in a very large number of material and fire scenarios.
Highlights
Analyses under extreme conditions make it possible to put a material in non-ambient conditions
The thermal response of composite laminate made of organic polymer matrix was investigated under severe temperature conditions as samples were exposed to high temperatures up to 750 ◦C
The field of composite materials with organic matrix does not escape this trend [11] and, in this work, we focus on the analysis of the hygro-thermo-chemico-mechanical properties of laminated composite materials in the case of fire resistance, i.e., in high temperature conditions and in the presence of an initial moisture content field
Summary
Analyses under extreme conditions make it possible to put a material in non-ambient conditions. The properties of that material are often drastically modified and new properties can be studied These properties could change when a material is subjected to severe environmental conditions of low or high temperatures [1,2], often coupled to a second stress such as an intense magnetic field, a light irradiation [3,4], a mechanical stress [5,6], or a high pressure [7,8]. The field of composite materials with organic matrix does not escape this trend [11] and, in this work, we focus on the analysis of the hygro-thermo-chemico-mechanical properties of laminated composite materials (organic polymer matrixes such as vinylester, polyester, or phenolic, with ceramic reinforcements such as E-glass or carbon fibers) in the case of fire resistance, i.e., in high temperature conditions and in the presence of an initial moisture content field
