Title: Fiber-reinforced sandwich panel
United States Patent 20030091805
The present invention may be embodied in a sandwich panel having first and second face panels each having a first predetermined thickness and being formed of a fiber-reinforced cementitious material. The sandwich panel further includes support frame for supporting the first and second face panels in a spaced apart configuration.
Title: Semi sandwich panel
United States Patent 20030126830
The present invention relates to a semi sandwich panel in which a cores material is partially formed in a portion which needs a strength and intensity between both surface finishing materials formed of a textile for thereby implementing a certain strength and intensity of a sandwich panel, so that it is possible to obtain a certain strength and intensity as a structure member which is a feature of a sandwich panel, and the number of fabrication processes is decreased, and the fabrication cost is decreased.
Title: Honeycomb sandwich panel
United States Patent 20020012767
In a honeycomb sandwich panel having a honeycomb core, and a front surface layer and a rear surface layer sandwiching the honeycomb core on its upper and lower surfaces, at least one of the front surface layer and the rear surface layer is made of a fiber reinforced plastic using a phenolic resin as a matrix.
Title: Sandwich panel with interior barrier
