Hybrid　lattice　structures　have　significant　potential　in　engineering　applications　owing　to　their　outstanding　mechanical　and　thermal　properties.　In　this　paper,　an　innovative　design　strategy　for　hybrid　lattice　structures　is　proposed　involving　the　integration　of　primitive　surfaces　with　truss　lattice　configurations.　This　approach　allows　for　the　full　exploitation　of　the　mechanical　and　thermal　properties　inherent　in　each　component,　leading　to　the　development　of　new　hybrid　lattice　structures.　Firstly,　the　quasi-static　compression　and　fluid-solid　coupling　heat　conduction　analysis　of　the　hybrid　lattice　structure　is　carried　out　by　numerical　simulation.　Then　the　effects　of　surface　wall　thickness,　and　truss　diameter　on　the　mechanical　and　thermal　properties　of　the　lattice　structure　are　discussed.　Additionally,　the　mechanical　performance　of　the　array　hybrid　lattice　structure　is　evaluated　through　quasi-static　compression　experiments.　These　experimental　results　are　compared　with　those　from　the　numerical　simulations,　validating　the　accuracy　of　the　simulation　model.　Finally,　a　multi-objective　optimization　model　targeting　specific　elastic　modulus　and　heat　dissipation　performance　(indicated　by　Nusselt　number)　is　established,　in　response　to　the　demand　of　aviation　and　aerospace　industries　for　lightweight,　load-bearing,　and　heat-dissipating　multi-functional　integrated　lattice　design.　The　non-dominated　sorting　genetic　algorithm　is　utilized　to　solve　the　optimal　model,　and　the　distribution　of　feasible　solutions　and　Pareto　front　are　obtained.　The　results　show　that　the　interpenetrating　hybrid　lattice　structure　has　a　greater　improvement　in　mechanical　and　thermal　properties　than　the　primitive　surfaces.　This　research　holds　significant　implications　for　the　design　of　multi-performance　hybrid　lattice　structures.　©　2024
