| Abstract: | An internal combustion engine cylinder block made of polymer composite materials has great importance in reducing the weight and raising the efficiency of automobile. The composite block is one of the development trends in the future.Numerical calculation of typical example delamination research and internal combustion engine block made of composite materials is worked out by means of structure elastic semi-analytics. Strain response of the internal combustion engine block is gained at some primary points by dynamic real time test under substantial load. Meanwhile result of calculation is verified by the test. This research proves that engine block made by composite material is feasible,and provides basis for constructional design of internal combustion engine block made of composite material. |
