摘 要：
Four kinds of structure design schemes are presented based on the researches to the composite properties,structure design principles and processing techniques requirements of railway sleeper composites.Among the schemes,the layer jacketed method is realized by combining materials performance and cost layering method,which ensures the performance of railway sleeper materials and reduces the cost with highest possibility.
