【 摘 要 】

A new technique for additive manufacture of composites has been developed, capable of 3D printing different compositions of asphalt with magnetic nanoparticles. Variation of the material feed ratio combined with precise fabrication geometries offers a simple avenue to functional grading of the materials properties. The integration of nanomaterials into milli-scale particle feedstock offers a new modality of nanomaterials handling, mixing and processing. We use X-ray computed tomography to quantify the functional grading and magnetic hyperthermia experiments to illustrate the functionalisation of the 3D printed composites. The technique is general and can be applied to a wide variety of materials; it has immediate application for repairing cracks in asphalt roads to modulate their properties and improve the lifetime of the repair.
