| description | The invention relates to a connection method of a composite material, in particular to a connection method of a C/C composite material, and solves the problems that when complex components are assembled through connection modes of rivets, bolts and the like in the prior art, a single rivet and bolt structure has failure modes of rivet breakage, thread tooth breakage and the like, and serious potential safety hazards exist on the complex structural components. The C/C composite material connecting method comprises the following steps: 1) preparing a carbon matrix from a carbon fiber preform to obtain at least two sub-components or at least two sub-components and at least one connecting piece with the density of 1.2-1.5 g/cm < 3 >; (2) an organic solvent and silicon powder or silicon alloy powder are stirred according to the proportion of 1: (2-4), the surfaces of the joints of the at least two sub-components or the surfaces of the joints of the at least two sub-components and the at least one connecting piece |
