Today, thermosets such as epoxy resins are frequently reinforced with either glass fibers or carbon fibers (also known as graphite fibers) (8,9). As an example calculation, the modulus of a unidirectional glass fiber-epoxy composite will be calculated in both the longitudinal and transverse directions. The properties of the materials are...

The arrow indicates where the entire sample failed, (b) The same type of data from debonding occurring in a single fiber specimen. Again, the arrow indicates when the entire sample fractured.

The other proach based on AFM that is commonly used to study the interface region is force modulation mode. Mai et al, probed the interface in glass fiber-epoxy composites, using force modulation, and concluded that the interface was 1-3 am thick and either ductile or brittle, depending on whether the fiber was sized or unsized, respectively. Munz et al, also used force modulation to characterize the stiffiiess in a carbon fiber/qioxy composite. Investigations of the cross-sections perpendicular to the axis of the carbon fiber were used to determine the thickness of the interface that was estimated to be between 20-80 nm.
