| 中文摘要: |
| 基于粉体喂料3D打印机研究3D打印玻璃纤维/热塑性聚氨酯共混材料的性能。结果表明：随着玻璃纤维质量分数增大，共混材料的拉伸强度呈先增大后减小趋势，当玻璃纤维质量分数为0.08时，共混材料的拉伸强度最大，为51.2 MPa，较热塑性聚氨酯提高41%；弯曲强度和压缩强度先减小后增大再减小，当玻璃纤维质量分数为0.15时，共混材料的压缩强度最大，为108.35 MPa；冲击强度呈先增大后减小趋势，当玻璃纤维质量分数为0.08时，共混材料的冲击强度最大，为15.52 kJ·m-2，较热塑性聚氨酯提高39%。 |

| The properties of 3D printing glass fiber/thermoplastic polyurethane blended material were investigated based on a powder feed 3D printer.The results showed that，with the increase of glass fiber mass fraction，the tensile strength of blended material increased first and then decreased.When the glass fiber mass fraction was 0.08，the tensile strength of blended material was the largest，which was 51.2 MPa and raised 41% than that of thermoplastic polyurethane.The bending strength and compressive strength were firstly decreased，then increased and then decreased.When the glass fiber mass fraction was 0.15，the compressive strength of blended material was the largest，which was 108.35 MPa.The impact strength increased first and then decreased.When the glass fiber mass fraction was 0.08，the impact strength of blended material was the highest，which was 15.52 kJ·m-2 and raised 39% than that of thermoplastic polyurethane. |
