Abstract過塩素酸アンモニウム(AP)粒子と末端水酸基ポリブタジエン(HTPB)を主成分とするコンポジット推進薬において,そのレオロジー特性を捉えるために粒子間隙パラメータγを導入する.γの小さな変化に対して推進薬スラリーの形状保持性が大きく変化した.レオロジー特性評価装置を用いて単一粒径で作製した異なるγの値を持つ模擬推進薬の粘弾性を温度別に測定した.特徴的な粒子配置が持つγの値に相当するγ=0.5 から損失弾性率がステップ状に減少した.また,試料温度の上昇に伴い損失弾性率のステップが緩やかになった.
We define the gap parameter γ, in order to understand the rheology of AP/HTPB composite propellant. A shape retainability of propellant slurry greatly changes with a slightly change in γ. The viscoelasticity of simulated propellants with different γ was measured using a rheometer at different temperatures. The loss modulus decreased stepwise from γ = 0.5. γ = 0.5 is equivalent to the value of γ of the particle arrangement that particles are in contact with each other in the simple cubic lattice. As the sample temperature rose, the step of loss modulus disappeared.
