在这项研究中，研究了由丙烯腈丁二烯苯乙烯（ABS）和石蜡组成的新型复合混合火箭燃料颗粒的燃烧性能，以了解将新型纳米材料：凝胶状碳点（CD）掺入石蜡组分中的效果。具有直端口的 ABS 燃料颗粒经过 3D 打印，并用作模具，将基础材料和 1 wt% CD 负载的石蜡材料分别浇注到模具中。为了进行控制，还打印了纯 ABS 燃料颗粒。所有燃料颗粒均使用实验室规模的测试装置进行弹道测试，其中使用气态氧 (GOX) 作为氧化剂。测试结果表明，负载 ABS/CD 的石蜡燃料颗粒的最大燃烧效率和回归率分别为 88% 和 1.29 mm/s，分别比 ABS/纯石蜡燃料颗粒提高了约 8.5% 和 11%。尽管机械性能有所妥协，但负载 CD 的燃料颗粒燃烧特性的增强归因于较低的粘度、较高的颗粒夹带、比表面积和催化活性
In this research, the combustion performance of a novel, composite hybrid rocket fuel grain composed of Acrylonitrile Butadiene Styrene (ABS) and Paraffin was investigated to understand the effects of incorporation of a novel nanomaterial: gel-like carbon dots (CDs), into the paraffin component. ABS fuel grains with straight ports were 3D printed and used as molds into which base and 1 wt% CD-loaded paraffin materials were casted separately. For control, pure ABS fuel grains were also printed. All fuel grains were exposed to ballistic tests using the lab-scale test setup where gaseous oxygen (GOX) was employed as oxidizer. Test results exhibited that ABS/CD-loaded paraffin fuel grains manifested a maximum combustion efficiency and regression rate of 88% and 1.29 mm/s, which marked enhancements of about 8.5% and 11% compared to ABS/pure paraffin fuel grains, respectively. Despite the compromise in the mechanical properties, the enhancement in combustion characteristics of CD-loaded fuel grains was attributed to lower viscosity, higher particle entrainment, specific surface area and catalytic activity
