Abstract
A study was conducted to improve the adhesion of propellant, liner,and insulation. Insulation was shown to be more advantageous in improving the adhesion when a barrier coat was applied compared to a bare insulation layer. It was confirmed that the adhesion strength between the insulation and the propellant improves as the thickness of the liner coating increases. The liner was cured for 24 h. If the liner is cured for a long time, it will adversely affect adhesion. Adhesion is also improved when a bonding agent is applied. As the bonding agent content increases, the adhesion improves. There is a change in the adhesive strength depending on the type of bonding agent used. HX-868 shows slightly more improved adhesion than HX-752.
