Investigating the Effect of Interface Morphology in Adhesively Bonded Composite Wavy-Lap Joints

Joints and interfaces are one of the key aspects design production composite structures. This paper investigates effect adhesive–adherend interface morphology on mechanical behavior wavy-lap joints with aim to improve performance. Intentional deviation from a flat joint plane was introduced in different bond angles (0°, 60°, 90° 120°) were subjected quasi-static tensile load. Comparisons made regarding conventional wavy joints. The visible failure modes that occurred within each configurations also highlighted explained. Load vs. displacement graphs produced compared, as well discussed both visually qualitatively. It observed distinct morphologies result variation load–displacement curve damage types. experience considerably higher due additional bending area, initial starts occurring at displacement. However, load level had its maximum value for single-lap Our findings provide insight development angle optimize behavior, which is widely some biological systems their
