Resistance Welded Joint of TI6AL4V Alloy-PEI/GF Composite Reinforced By Candle Soot Coating

Abstract

PEI/GF lamination and TI6AL4V alloy are often related to the poor wettability of PEI to TI6AL4V alloy at the interface layer. To overcome these problems, an in situ synthetic candle soot reinforcing coating on TI6AL4V alloy was added into the place of the bonding area. The mechanical properties of composite joints were evaluated by single lap shear strength (LSS) tensile test. The mechanism of strengthening TI6AL4V-PEI/GF joint by candle ash was compared.
