Unravel melt pool and bubble dynamics during laser powder bed fusion of polyamides using synchrotron X-ray imaging and process simulation

Virtual and Physical Prototyping
Laser powder bed fusion (LPBF) of Polyamide 12 (PA12) using a near-infra-red (NIR) beam is largely unexplored; therefore, the beam-matter interaction, evolution mechanisms of the melt pool and defects remain unclear. Here, we employed a combination of in

effect of compatilizer pp-g-mah on the morphology and properties of pp/pa12 system [PDF]

, 2009
采用熔融共混制备了不同相容剂马来酸酐接枝聚丙烯(PP-g-MAH)含量的聚丙烯(PP)/PP-g-MAH/聚酰胺12(PA12)共混体系,通过对体系的平衡扭矩、差式扫描量热法(DSC)、扫描电子显微镜(SEM)及力学性能等测试,分析了共混体系中相容剂PP-g-MAH对PP/PAl2形貌及性能的影响.结果表明,PP-g-MAH能改善PP/PAl2的界面相容性,PA12能更好地分散在PP基体中,最佳相容剂添加质量分数为12%.此时,杨氏模量比未添加相容剂时提高了60.7%,断裂伸长率提高了79.9 ...

Material Selection and Geometric Design for Few‐filament Shape Memory Polymer Yarns for Force Generation

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
A custom shape memory polymer material selection process relates quantitative application criteria (e.g., compression garment yarns) to material characterization information. The selected materials are manufactured into yarn geometries, which expand the design space by creating structural stress‐strain profiles beyond the nominal material stress‐strain
