Abstract

Fiber
metal laminate (FML) is an advanced composite material that combine the
advantageous of both fiber reinforced composites and metal alloys without
sharing their individual disadvantages. When it is compared to commonly known
fiber reinforced polymer composites, the FML provide better impact resistance
and fatigue strength. But the production of a FML composite is a major problem
since the bonding at fiber-metal interface can be poor. For this reason, the
adhesion bonding capability at the fiber-metal interface was investigated in
this study. Carbon fiber and glass fiber fabrics having both  ±45° and 0°-90° orientation were used as
fiber layers. And extremely thin stainless steel materials in the mesh form
were used as metal layers. The mesh sizes of the layers are 100 and 500
respectively. The produced specimens having 12 different configurations were
subjected to  single lap shear tests
according to ASTM D 5868-01 Standard. The results showed that 500-mesh
stainless steel favorably affected the adhesion bonding strength.
