repair sheets
1.It were shown that carbon mixed with glass fibers (under quasi-isotropy plying) used as patch to repair aluminium sheets with a center hole could meet the demond of bonding-repair. Compared with carbon fiber composite, the thermo-expansion coefficient was increased from 1.01×10-6K-1 to 3.41×10-6K-1, mostly approaching the thermo-expansion coefficient of aluminium alloy.
