Heat protective sleeve
A heat protective sleeve includes a body being a sleeve extending along a longitudinal direction, and comprising a triply periodic minimal surfaces (TPMS) structure between an inner diameter of the body and an outer diameter of the body. The TPMS structure has open spaces in communication with ambient air at the outer diameter of the body, and the inner diameter of the body is configured to contact a surface adjacent to the inner diameter. A strip extends along the longitudinal direction on a portion of the body. The strip is a same material as the TPMS structure, and the material of the strip is solid and without holes through it.
