碩士 === 中華科技大學 === 飛機系統工程研究所 === 99 === Abstract This study reinforced sandwich composite materials design and structure of the specimen bending function tests, designed laminated glass fiber surface and intermediate density for the 30k guarantee Lilong composite sandwich the sandwich specimens were laminated with the laminated direction, the direction angle is 〔0 / 90〕 degrees, and develop production sandwich composite specimen method, the use of the upper and lower layers of 4 layers of glass fiber reinforced section and adding structure to make the structure into a shape of a wave function to investigate the structural strength of the difference. Test composite sandwich structure to withstand the maximum bending strength. Design of light weight, carrying high pressure, convenience and cost savings made sandwich composite sample is the main purpose. In this paper, reference to ASTM specifications as the basis of experiments, specimens of reinforced sandwich composite design experiments, and principles of the implementation of three-point bending test, together with structural reinforcement and improvement of Article I value, I value the stronger the compressive and tensile strength also would be a great improvement, so the thesis utilizes the material to add structural reinforcement bar to improve the brittleness of epoxy resin, laminated fiber materials to improve the tensile and compressive ability to improve their compression strength after impact, the results can be used in a variety of green energy and industrial materials selection based on people's livelihood and reference. Keywords: ASTM standard, composite materials, structural reinforcement section, I value.
