Mathematical Models for Designing Composite Materials with Barrier Properties

Математические модели для проектирования композиционных материалов с барьерными свойствами

Abstract

Одним из важных направлений обеспечения химической безопасности являются разработка и совершенствование средств индивидуальной защиты для персонала химически опасных объектов и аварийно-спасательных подразделений МЧС. Современные средства индивидуальной защиты от опасных веществ выполняются на основе многослойных полимерных композиционных материалов с барьерными свойствами. Обоснована актуальность математического моделирования процессов тепломассопереноса при проектировании этих изделий и материалов для них, с учетом широкого набора воздействующих токсичных и агрессивных сред и различных по мощности и природе тепловых факторов. В статье представлен обзор математических моделей для описания тепло- и массопереноса через полимерные (в том числе композиционные) материалы, теплозащитные покрытия, поглощающие системы. Приведены наработанные к настоящему времени приемы решения входящих в них уравнений, которые успешно используются в смежных областях инженерной деятельности и могут быть рекомендованы для проектирования новых защитных материалов и покрытий. One of the most urgent tasks of ensuring chemical safety is the development and improvement of personal protective equipment required for the work of the staff of chemically hazardous facilities and emergency rescue units of the Ministry of Emergencies. Modern personal equipment for protection against hazardous substances is based on multilayer polymer composite materials with barrier properties. The relevance of mathematical modeling of heat and mass transfer processes used for designing these products and materials is justified, taking into account a wide range of toxic and aggressive environments and thermal factors of different types and origin. The article provides an overview of mathematical models describing heat and mass transfer through polymeric (including composite-based) materials, heat-protective coatings, absorbing systems, etc. A series of developed to date techniques for solving the appropriate equations are summarized, which have been successfully used in related engineering fields and can be recommended for designing novel protective materials and coatings for the corresponding purpose.
