    摘要： The invention is to perform operations from sealing of a honeycomb core with a thermosetting sealing material having an adhesive property to its hardening in one step, prevent a resin from flowing into cells of the honeycomb core during resin impregnating operation, and thereby mold low-cost honeycomb sandwich components by using RTM technique which is adopted in molding solid materials, for instance. Dry fabric sheets are stacked on both sides of a honeycomb core with thermosetting sealing members having an adhesive property placed in between, and the sealing members and the dry fabric sheets are heated at the curing temperature of the sealing members to cause initial hardening of the sealing members and to dry the dry fabric sheets. Then, the dry fabric sheets are impregnated with a thermosetting resin and the resin impregnated into the dry fabric sheets is hardened by hot-pressing an entire assembly thus prepared under specific conditions.

    摘要： A method for forming a honeycomb sandwich composite panel comprising dry fabrics, an unpermeating-resin film, a non-low-viscosity-resin film, a honeycomb core, a non-low-viscosity resin film, an unpermeating-resin film and dry fabrics, stacked in this order in a mold. The cells of the honeycomb core are sealed by the laminated films. The unpermeating-resin film prevents the excessive permeation of the resin which forms the laminated films into the dry fabrics and to enhance the adhesion of this resin to the honeycomb core by forming proper fillets of the resin of the laminated sealing films. Further, drying process for drying the dry fabrics enables the application of the RTM process to the formation of the honeycomb sandwich composite panel.
