Abstract
In this study, it is evaluated for fracture toughness to analyze crack resistance properties of particulate reinforced composite propellant. Fracture toughness test using WST specimen is conducted by temperature conditions from $\small{50^{\circ}C}$ to $\small{-60^{\circ}C}$. Evaluation method for fracture toughness calculated using an equation suggested by ASTM E399 with linear elastic fracture mechanics. From these result, splitting loads and stress intensity factors of propellant increase according to decrease of test temperature. Also, the strain fields of specimen surface using digital image correlation increase as temperature decreased from $\small{50^{\circ}C}$ to $\small{-40^{\circ}C}$, but it sharply decreases at $\small{-60^{\circ}C}$ because of brittle behavior.
