用于制造很小或没有残余应力的弯曲夹层结构的低能量工艺
摘要：
用于制造很小或没有残余应力的弯曲夹层结构的低能量工艺。用于制造包括微桁架结构的弯曲梁的工艺。在一个实施例中，所述工艺包括在底部面板上制造所述微桁架结构，其中所述微桁架结构仅部分固化使得其可容易地弯曲，且然后使所述局部固化微桁架结构和底部面板在弯曲的固定装置上方成型，在此处然后完全固化和硬化所述局部固化微桁架结构至其最终的弯曲状态。然后附接顶部面板至所述微桁架结构的顶部表面。在可替代实施例中，迫使弯曲的底部面板抵靠固定装置变平，且当所述底部面板固定至所述固定装置时使所述微桁架结构成型至局部固化状态。然后所述底部面板从所述固定装置释放，其引起它返回至它的弯曲构型，从而引起所述微桁架结构来弯曲。
摘要（英）：

A process for fabricating a curved beam including a micro-truss structure. In one embodiment, the process includes fabricating the micro-truss structure on a bottom facesheet, where the micro-truss structure is only partially cured so that it is readily bendable, and then forming the partially cured micro-truss structure and bottom facesheet over a curved fixture, where the partially cured micro-truss structure is then fully cured and hardened to its final curved state. A top facesheet is then adhered to a top surface of the micro-truss structure. In an alternate embodiment, a curved bottom facesheet is forced flat against a fixture and the micro-truss structure is formed while the bottom facesheet is secured to the fixture to a partially cured state. The bottom facesheet is then released from the fixture, which causes it to return to its curved configuration causing the micro-truss structure to bend.
