We propose to develop a multi-material polymer manufacturing system for pre-forms of mesostructured polymer/polymer, Polymer/gas, and polymer metal composites that can be drawn down into fibres with micro and nanoscale features to produce infrared emissivity tunable metamaterials. These fibers are in high demand for military camouflage and would act as the outer surface of tarps or military uniforms to permit changeable thermal emissivity, absorption or scattering properties to enhance survivability of soldiers and vehicles on battlefields where adversaries have access to hyperspectral imaging capabilities (heat vision). The specific outcomes in this project are to develop the full manufacturing capabilities needed to produce the pre-forms using a customized additive manufacturing extruder system, and the thermal drawing capabilities to convert multi-material macroscale preforms into the metamaterial fibres with desired IR properties.

我们建议开发一种多材料聚合物制造系统，用于介观结构聚合物/聚合物、聚合物/气体和聚合物金属复合材料的预成型件，可以将其拉制成具有微米和纳米级特征的纤维，以生产红外发射率可调的超材料。 这些纤维对军事伪装有很高的需求，可用作防水布或军服的外表面，以允许改变热发射率、吸收或散射特性，以提高士兵和车辆在战场上的生存能力，在战场上敌人可以获得高光谱成像能力（热视觉）。 该项目的具体成果是开发使用定制增材制造挤出机系统生产预成型件所需的完整制造能力，以及将多材料宏观预成型件转化为具有所需红外特性的超材料纤维的热拉拔能力。
