Influence of Density on the Thermal Conductivity of Fiberglass Felt Yong Yang1,a,Xueyu Cheng2,b, Zhaofeng Chen1,c,Renli Fu1,d,Zhou Chen1,e, Jinglian Qiu1,f,Dan Su1,g 1College of Material Science and technology, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, P.R.China 2Suzhou V.I.P.New Material Co., Ltd., Hong Da Fang Yuan Group, Suzhou 215000, P.R.China *Corresponding author.E-mail:zhaofeng_chen@163.com Keywords: Thermal conductivity, Density, Fiberglass felt, Heat-transfer mechanism.
Introduction Fiberglass felt are used widely as insulations and building sections in commercial and industrial applications[1].Coefficient of thermal conductivity for the Fiberglass felt is an important index,which could evaluate the thermal insulation performance of the fiberglass felt.In general,thermal insulations are classified into the following two types of materials:isotropic materials with a uniform thermal conductivity and anisotropic materials with a nonuniform thermal conductivity[2].Fiberglass felt are the isotropic materials.The thermal conductivity of the material is defined as the amount of heat crossing a unit area of the material per unit time per unit temperature gradient[3].In porous materials heat is propagated by three processes:thermal conductance through the solid and both radiation and convection through the pores[3].
In this paper,using this heat-transfer mechanism of the porous materials explains the relationship between thermal conductivity and density of the fiberglass felt.
Generally speaking,thermal properties of a fibrous material depend on:thermal properties of each phase(fiber and air),fiber volume fraction,and fiber size, orientation and mass distribution[4].The value of the thermal conductivity of heat-insulating materials,among which are fibrous materials,is affected by their density and kind,the size and location of pores,the chemical composition and molecular structure of hard constituents,the emissivity of surfaces bounding the pores,and the kind and pressure of the gas filling the pores[5].Main aim of this paper is to describe the relationship between thermal conductivity and density.According to the aim,we study the effect of density of fiberglass felt and analysis the reason.

If a high-conductivity driver expands a low-conductivity specimen or the specimen is given an inner coating, for example of copper, specimens of bad conductors and nonconducting materials, such as engineering ceramic, which is appealing due to its unique features especially the high strength, high hardness and low density may also be tested.
This research can be available for reference for the application and development of fragile material test technique.
