Abstract

An experimental investigation on the mechanical properties of scarf jointed CFRP laminates with impact damage was carried out. This paper shows the influence of the scarf angle on various characteristics, namely tensile strength, damage after impact, and tensile after impact (TAI) strength. Such influences were investigated experimentally by using four variations of scarf angles of 2°, 3°, 4.5°, and 6°. As a result of the tensile test, it was found that the tensile strength decreases as the scarf angles increases. As a result of the cross-sectional observation and TAI test, it was found that the TAI strength of the scarf joints was much affected by the fact that the debonding length of the adhesive layer varies depending on scarf angle.
