PREPARATION AND FLEXURAL ANALYSIS OF BALSA WOOD CORE SANDWICH COMPOSITE BRIDGE DECK REINFORCED BY LATTICE WEBS
摘要
Abstract
This study proposed a new sandwich composite bridge deck reinforced by lattice webs to replace the used bridge deck because of its high bending stiffness,high strength to weight ratios and corrosion resistance,etc.The surface layers,lattice web and core material are integrally formed in the mould at one time through vacuum infusion process,and lattice web integrates surface layers and core material into a whole organically,which thus greatly improve the performance of the new bridge deck.The flexural analysis of the panel is carried out by using the theory of composite sandwich structure.The results show that the stiffness of the new bridge deck can be satisfied.Both normal stress of the fiber surface and the shear stress of the wood core can meet the strength requirements,and the weight of the bridge panel is greatly reduced by 57％.关键词
