| Abstract: | The infiltration process in the liquid extrusion of composites is the key factor that influences the solidification of metal matrix and distribution of fibres. The infiltration model in liquid extrusion of composites was built according to the need of practical technology design, the numerical simulation of its temperature fields was carried out with the similarity solution, and then the temperature variation rule and the effect of infiltration pressure and fibre volume fraction on temperature fields was got. |
