Honeycomb structure for FRP sandwich panel

摘要

PPROBLEM TO BE SOLVED: To provide an FRP sandwich panel which is light in weight and can hardly be peeled off. PSOLUTION: The plane aggregate of hollow pillar-like cells is provided. Expandable resin particles are set in the hollow parts of the cells. Reinforcing fibers are arranged on the two main surfaces of a honeycomb structure in which a resin for an FRP matrix is packed in the openings of the cells to cover the expandable resin particles and placed in a mold. After mold clamping, the resin is melted by heating, and the expandable resin particles are expanded. The molten resin is extruded into the reinforcing fibers, and the resin is cured.
