Abstract

Based on the analysis of the literature on the possibility of using neural networks to create new materials with high functional properties, the article considers a solution to the problem of determining the operational stability of polymeric composite materials by creating physical and chemically sound mathematical prediction models. Epoxy resins of the UP-637 and EA brands with an isophorone diamine hardener were chosen as the matrix of the model composite material, and oligobutadiene rubber of the SKN-10 KTR brand was chosen as the modifier. It justifies directions of work necessary for development of new materials creation methodology with optimal characteristics, building a model for changing the properties of materials at variation of composition and implementation of full-scale mathematical modeling of physical and chemical processes of polymer composite materials aging at changing level and time of climatic factors influence. Verification of the obtained dependence of service characteristics on the composition of the material and the level of influencing climatic factors was carried out on the basis of data from full-scale tests in a temperate climate. The proposed methodology for modelling the properties of polymer composite materials will reduce the development time of new materials and allow creation of polymer composites based on epoxy resin containing fillers of various natures (carbon, mineral and polymer) with high performance parameters.
聚合物复合材料生成过程和老化的数学建模
基于对利用神经网络创造具有高功能特性的新材料的可能性的文献分析,文章考虑了通过创建物理和化学上合理的数学预测模型来确定聚合物复合材料的工作稳定性问题的解决方案。文章选择 UP-637 和 EA 品牌的环氧树脂和异佛尔酮二胺固化剂作为模型复合材料的基体,并选择 SKN-10 KTR 品牌的低聚丁二烯橡胶作为改性剂。这为以下工作指明了方向:开发具有最佳特性的新材料制造方法、建立在成分变化时改变材料特性的模型,以及在气候因素影响水平和时间不断变化的情况下,对聚合物复合材料老化的物理和化学过程进行全面数学建模。根据在温带气候条件下进行的全尺寸试验数据,验证了所获得的使用特性对材料成分和气候影响因素水平的依赖性。所提出的聚合物复合材料性能建模方法将缩短新材料的开发时间,并可在环氧树脂的基础上制造出含有各种性质填料(碳、矿物和聚合物)的具有高性能参数的聚合物复合材料。
