Abstract: A structural composite laminate and method of making the same are provided. The laminate includes first and second skins or laminas, and a core positioned between the first and second laminas. The core contains thermoplastic and/or substantially inelastic polymeric particles with inter-particle interstices between the polymeric particles. Optionally, the polymeric particles are arranged discontinuously to establish gaps between adjacent particles along at least one dimension of the laminate.
