Abstract

AbstractThis research focused on the development of a honeycomb fabric by predicting the areal density suitable for aircrew helmet liner. The aim was to fulfill the requirements for the lightweight and mechanical properties of composite liner. The model was based on the structural characteristics of the preform, including the weave design and geometric parameters. The predicted areal density, based on varying yarn linear density and the number of picks in the free and bonded wall, was compared to experimental results and showed good agreement. A geometric model was derived to predict the areal density of 3D woven honeycomb preforms for producing the composite liner of aircrew helmet. The model was validated using experimental data from a variety of 3D woven honeycomb preforms, showing that it accurately predicts the areal density and can be used as a tool to design 3D woven honeycomb preforms for advanced composites.Keywords: Aircrew helmet liner3D woven honeycomb fabricareal densitylightweight compositegeometrical modeling AcknowledgmentsWe are grateful to the Defence Research & Development Organisation (DRDO) for sponsoring the project (Project code-RP04187) at the Focus Incubation Centre of 3D Weaving and Structural Composites, Indian Institute of Technology Delhi.Disclosure statementNo potential conflict of interest was reported by the authors.

轻型机组头盔衬垫三维编织蜂窝织物的几何建模与实验验证

摘要通过预测面密度，研制了一种适用于空勤人员头盔衬垫的蜂窝状织物。其目的是满足复合衬垫的轻量化和机械性能要求。该模型基于预制件的结构特征，包括编织设计和几何参数。根据纱线线密度和自由壁和粘接壁中纱条数的变化，预测的面密度与实验结果吻合较好。建立了用于制造机组头盔复合衬垫的三维编织蜂窝预制件的面密度几何模型。利用多种三维编织蜂窝预制件的实验数据对该模型进行了验证，结果表明，该模型能够准确预测蜂窝预制件的面密度，可作为设计先进复合材料三维编织蜂窝预制件的工具。感谢印度国防研究与发展组织(DRDO)在德里印度理工学院3D编织和结构复合材料重点孵化中心赞助该项目(项目代码r04187)。披露声明作者未报告潜在的利益冲突。
