[ 1 ] - بررسی راهکارهای بهبود خواص حرارتی و مکانیکی پلییورتانهای بر پایه گلایسیدیل آزید پلیمر(علمی-ترویجی)
Glycidyl azide polymer (GAP) is a unique elastomeric binder with high heat of formation and high density due to enhanced thermal and performance properties of composite solid propellants. However, GAP has high glass transition temperature and poor mechanical properties that are limited its application as a binder in a composite solid propellant. In this paper , the efforts carried out on modifi...
[ 2 ] - بررسی خواص مکانیکی و حرارتی کوپلی یورتان های بر پایه GAP-PPG با نسبت های متفاوت
For improving the mechanical and thermal properties of polyurethanes based on glycidyl azide polymer (GAP), a series of polyurethane elastomers with two soft segments were prepared from hexamethylene diisocyanate (HDI) / (GAP) / (PPG) /TMP and isophorone diisocyanate (IPDI) / GAP/ PPG/ TMP formulation. The weight ratio of soft segments GAP/PPG in polyurethane samples is changed as following ord...
[ 3 ] - بررسی خواص حرارتی و مکانیکی پلی یورتانهای بر پایه GAP
Glycidyl Azide Polymer is one of the most important energetic binders that is used in the composite solid propellant formulation. GAP is a unique binder with a positive heat of formation (+117.2 kJ⁄mol). In addition, GAP has good thermal and physical properties such as low glass transition temperature, low viscosity and high density compared to other energetic binders. GAP can be used as a bin...
