Publication number: 20210137184Abstract: Generally described, aspects of the disclosed subject matter are directed to impact mitigating membranes. In accordance with aspects of the present disclosure, the impact mitigating membranes generally include a laminar core having a first lamina and a second lamina coupled to the first lamina and configured to shift relative to the first lamina to dissipate kinetic energy resulting from an oblique impact force. The laminar core may include a lubricating layer or self-lubrication between the lamina to reduce friction. In general, the laminar core is surrounded by first and second encapsulating layers positioned adjacent each lamina. An anchoring attachment coupled to one or more of the first and second encapsulating layer and associating with the laminar core constrains relative lateral motion between the laminar core and the first and second encapsulating layers.Type: ApplicationFiled: March 6, 2018Publication date: May 13, 2021Applicant: SIMON FRASER UNIVERSITYInventors: Daniel Eamon ABRAM, Farid GOLNARAGHI, Gaofeng Gary WANG
