摘要：
In order to fabricating gun propellants with complex structure, the photocurable gun propellants consisting of ultraviolet curable resin as binder and CL-20 as energetic solid additive are prepared by the material extrusion 3D printing technology. The mechanical properties and combustion performances of printed gun propellants are studied. The results show that the gun propellants with 70% solid content presents good adhesion between the extrusion layers after optimization of the printing conditions. The tensile strength and compressive strength of the printed gun propellant are 10.21MPa and 50.94MPa, respectively. Compared with triple-based gun propellants, the mechanical strength of printed gun propellant is higher, while the maximum deformation rate is smaller. The burn rate of the printed gun propellant was 17.88cm/s at 100MPa and the pressure exponent is 1.47, showing that the application of the material extrusion 3D printing technology for photocurable gun propellants is feasible. © 2022, Editorial Board of Journal of Explosives & Propellants.
