Abstract: A lightweight panel for a vehicle includes a honeycomb part including a paper honeycomb having an inside formed in a honeycomb structure and machined to have a predetermined thickness. The panel also includes a reinforcing layer formed of a reinforcing mat and a reinforcing resin, formed on each of upper and lower surfaces of the honeycomb part. The honeycomb part is formed to be thinner toward a perimeter thereof.

Abstract: A lightweight panel for a vehicle includes a honeycomb part having a paper honeycomb whose interior is formed in a honeycomb structure and is machined to a predetermined thickness, a reinforcing layer including a reinforcing mat and a reinforcing resin, formed on each of upper and lower surfaces of the honeycomb part, and a plurality of concave portions formed in a lower surface of the honeycomb part.

Abstract: A method of manufacturing a lightweight panel for a vehicle includes a mat fixing operation of manufacturing a first semi-finished product by fixing a mat to each of upper and lower surfaces of a paper honeycomb in a predetermined thickness and a resin spraying operation of manufacturing a second semi-finished product by applying a resin to each of upper and lower surfaces of the first semi-finished product. The method also includes a thermal molding operation of manufacturing a third semi-finished product by thermally molding the second semi-finished product between a heated upper thermal mold and a heated lower thermal mold, a sheet attaching operation of manufacturing a fourth semi-finished product by attaching a sheet molded on an upper surface of the third semi-finished product, and a trimming operation of cutting an unnecessary area of the fourth semi-finished product.

Abstract: Disclosed herein are a bar code encoding system and a bar code decoding system. The bar code encoding system includes a method for compressing the original data and adding data for error detection and correction to the compressed data to generate a large capacity 2-dimensional color bar code so as to be used as prints in an off-line environment and a large capacity 2-dimensional bar code pattern. The decoding system includes a method for receiving the prints including the 2-dimensional bar code generated by the encoding system through an input device such as a scanner and a camera, searching the 2-dimensional bar code to recognize it, performing color correction and error detection and correction, decompressing the compressed data to decode the original data.
