Barrel is the key part of artillery. In shot process, propellent gas of high pressure and high temperature flows in the tube at a high rate of speed, which brings an upheaval to the temperature field of the composite barrel. As to the composite barrel with metal inner, its poor thermal conductivity is more likely to cause uneven temperature distribution and bigger temperature gradient, to produce improper deformation and to make the work temperature of metal inner rise, all of which will affect the life span of barrel.

身管是火炮的关键部件，在火炮发射过程中，高温、高压的火药燃气在身管内成脉冲式高速流动，使身管受到急剧的加热，引起身管壁内的温度急剧变化，而对于带金属内衬复合材料身管，由于复合材料导热性能较差，更容易引起非均匀温度分布以及较大的温度梯度，产生不合适的变形，也会使身管的金属内衬的工作温度升高，从而使得身管的寿命降低，同时身管的发热会引起其刚度的变化，增大射弹散布。
