    摘要: A monomeric formulation for creating self-propagating polymer optical waveguides and a system and a method of using the same. The monomeric formulation includes a plurality of unsaturated molecules, a molecule having a structure of R—X—H (e.g., X═O, S, N), and a photoinitiator. The monomeric formulation can further include a free radical inhibitor. The system includes a light source, a reservoir having a monomeric formulation and a patterning apparatus configured to guide a light beam from the light source into the monomeric formulation to form at least one self-propagating polymer waveguide.

    摘要: Pre-ceramic monomer formulations for creating self-propagating polymer waveguides, and a system and method of using the same, is disclosed. The formulation includes a plurality of unsaturated molecules, wherein the unsaturated molecules contain a significant amount of non-carbon atoms, a molecule having structure of R′—X1-H (e.g., X1=O, S, N), and a photoinitiator. R′ can also have non-carbon atoms. The system includes a light source, a reservoir having a monomer formulation and a patterning apparatus configured to guide a light beam from the light source into the pre-ceramic monomer formulation to form at least one self-propagating polymer waveguide and can be directly converted to interconnected three-dimensional ceramics.

    摘要: A method for fabricating a radiation-cured structure is provided. The method includes the steps of providing a first radiation-sensitive material and a second radiation-sensitive material adjacent the first radiation-sensitive material. The first radiation-sensitive material has a first sensitivity. The second radiation-sensitive material has the first sensitivity and a second sensitivity different from the first sensitivity. At least one mask is placed between at least one radiation source and the first and second radiation-sensitive materials. The mask has a plurality of substantially radiation-transparent apertures. The first and second radiation-sensitive materials are then exposed to a plurality of radiation beams through the radiation-transparent apertures in the mask to form a first construct in the first radiation-sensitive material and a second construct in the second radiation-sensitive material. The first construct and the second construct cooperate to form the radiation-cured structure.

    摘要: A micro-truss based blast protection apparatus. In one embodiment, the blast protection apparatus includes a three-dimensional (3D) ordered truss core between a first face plate and a second face plate. The 3D ordered truss core includes first truss elements defined by first self-propagating polymer waveguides and extending along a first direction, second truss elements defined by second self-propagating polymer waveguides and extending along a second direction, and third truss elements defined by third self-propagating polymer waveguides and extending along a third direction. The first, second, and third truss elements interpenetrate each other at a plurality of nodes to form a continuous material. The first, second, and third truss elements define an open space for providing a densification in response to a force applied to the first face plate and/or the second face plate, and the 3D ordered truss core is self-supporting.
