A heat resistant laminate structure is provided which comprises: (a) a thermoplastic polymer matrix core layer having an upper and lower surface and within which is located a strata of voids; positioned at least substantially within at least a substantial number of voids is at least one spherical void-initiating particle which is phase distinct and incompatible with the matrix material, the void space occupied by said particle being substantially less than the volume of said void, with one generally cross-sectional dimension of said particle at least approximating a corresponding cross-sectional dimension of said void; (b) a void-free thermoplastic skin layer affixed to the upper surface of core layer (a); and, (c) a thermoplastic polymer foam layer affixed to the lower surface of core layer (a).
