NC/GAP的3D打印及性能
3D Printing of NC/GAP and its Performance
摘要
Abstract
To study the structure and performance of NC/GAP printed samples,nitrocellulose(NC)and glycidyl azide polymer(GAP)were used as raw materials to prepare NC/GAP printed samples with GAP mass fractions ranging from 0%to 30%via 3D printing.The structure,thermal stability,combustion performance and mechanical properties of NC/GAP composites were char-acterized by field-emission scanning electron microscopy(FE-SEM),fourier transform infrared spectroscopy(FT-IR),differential scanning calorimetry(DSC),high-speed camera,oxygen bomb calorimeter and universal tensile testing instrument.Results show that the NC/GAP printed samples have regular morphologies,with no obvious interface between the internal layers.With the increasing of GAP content,the thermal stability gradually enhances,the compatibility between NC and GAP gradually deteri-orates,the tensile strength gradually decreases,and the combustion rate shows a trend of first increasing and then decreasing.When the mass fraction of GAP is 10%,the maximum combustion rate reaches 25.6 mm·s-1,which is 46%higher than that of NC.When the mass fraction of GAP increases from 0%to 30%,the heat of combustion in air and argon increase from 2843.2 J·g-1 to 5260.1 J·g-1 and 1065.7 J·g-1 to 1938.7 J·g-1,increasing by 85%and 82%,respectively.关键词
