The　bistable　composite　laminates　are　kind　of　structural　unit　with　two　stable　equilibrium　states.　Due　to　the　complexity　of　mathematics,　the　mechanical　analysis　of　trapezoidal　plates　is　seldom　studied,　which　can　provide　theoretical　basis　for　the　development　of　deformable　intelligent　structures　such　as　collapsible　structures,　deformable　wings　and　energy　concentrators,　though.　Based　on　the　classical　theory,　a　new　model　of　trapezoidal　cross-laminated　bistable　laminates　is　presented　in　this　paper.　Using　the　principle　of　minimum　potential　energy,　Newton-Raphson　technique　and　the　application　of　higher　order　polynomials　in　the　configuration　function,　two　steady　state　configurations　of　trapezoidal　laminated　plates　with　different　geometrical　sizes　under　free　boundary　conditions　are　studied.　In　addition,　flexible　intelligent　piezoelectric　microfiber　composite　(MFC)　actuators　are　used　to　trigger　the　snap-through　between　two　stable　configurations　of　bistable　laminates.　The　voltage　required　to　drive　the　change　of　bistable　structure　of　trapezoidal　laminates　is　calculated.　The　calculation　of　the　bistable　model　has　a　certain　guiding　significance　for　the　design　and　manufacture　of　equipment　and　mechanism　under　various　special　circumstances.
