WebNov 22, 2024 · The observed dependence on graphite volume fraction can be modeled using linear regression; dependence of the Cu–graphite composites’ coefficients of thermal expansion on the volume fraction of graphite was fitted using the least square method: α comp = (−14.15.n Vgr + 18.45) × 10 −6 K −1 with an R 2 value of 0.972. WebThe CTE of C/C composites abides by the mixture regulation, α c =νf·α cf +νm·α cm, (1) where Vf and Vm denote the volume fraction of the CF and PyC respectively, α f andα m stand for the CTE of the CF and PyC respectively. The value of exponent c is about equal to 1. So the above expression becomes α=νf·α f +νm·α m, (2)
