Abstract
Description
α=0.1388*d2/t50 (1)
式において、dはマイクロメートルで測定されるサンプルの厚さであり、t50は後面が最高温度上昇を達成する時間の半分である。比熱(Cp)は、ジュール毎グラム毎ケルビン(J/gK)で測定し、密度(ρ)は、グラム毎立方センチメートル(g/cm3)で測定する。比熱は、試験サンプルと公知の比熱の標準サンプルの間の比較により測定する。密度は水浸法(ASTM D792)を用いて決定する。熱伝導率は、下記式(2)に示されるように計算することができる。
k(T)=α(T)*cp(T)*ρ(T) (2)
式において、k(T)は、熱伝導率を示し、α(T)は熱拡散率を示し、cp(T)は、比熱を示し、およびρ(T)は、試料の密度を示す。
2厚さ貫通はセテックス多層シートである。
3アルミニウムシート。
1側および2側は、同じサンプルを両側で試験したことを示す(試験、反転、および再試験)。結果の差は構造におけるひずみ/そりによる。
