Bonding
Critical fiber sizing
To achieve desirable properties in composite components, adhesion between fiber and matrix must be optimized. Adhesion requires sufficient saturation with resin (wetout) at the fiber/matrix interface. To ensure good adhesion, attention must be given to fiber surface preparation, such as the use of a surface finish or

Testing Tech: Adhesion testing of sandwich panels
In my three preceding columns, I discussed the testing of sandwich panels as unit structures. This included flexural and shear testing of beams and panels. However, such tests — and hardware components that are designed accordingly — will not produce the desired results unless the adhesives that hold these panels

Automaker BMW stepped outside the box when it recently adhesive bonded carbon fiber/epoxy roofs to 1,500 limited-edition BMW M3 CSL sedans. The automaker wanted to enhance the car's performance by shedding as much weight as possible — other composite components include the doors, front skirt, trunk lid and rear bumper
