  • Method and apparatus for continuously fabricating a composite sandwich structure
    Patent number: 10821651
    Abstract: A method for continuously fabricating a composite sandwich structure includes the steps of: (1) preheating a laminate to a preforming temperature above a glass transition temperature of the laminate but below or equal to a crystalline melt temperature of the laminate as the laminate is substantially continuously moved through a preheating zone, wherein the laminate comprises a first face sheet, a second face sheet and a core sandwiched between the first face sheet and the second face sheet; (2) consolidating the laminate as the laminate is substantially continuously moved through a consolidation zone in line with the preheating zone to form a continuous length of the composite sandwich structure; (3) moving the composite sandwich structure, substantially continuously, through at least one of a texturing zone and a coating zone; and (4) incrementally applying at least one of a surface texture and a surface coating to at least one surface of the composite sandwich structure.
