Characterization and Performance of a Self -Healing Composite Material
… with embedded microcapsules and catalyst. Double-cantilever-beam (DCB) and width-tapered double-cantilever-beam (WTDCB) specimens were tested to study the healing of delamination in composites by comparing the toughness of the virgin specimen with the toughness of the same specimen after …

Self-healing of high temperature cured epoxy and composites
… epoxy adhesive were evaluated using the width-tapered-double-cantilever-beam (WTDCB) specimen geometry. The same healing system was then incorporated into a commercial high temperature cured rubber toughened epoxy adhesive, FM®73M. The addition of 117 μm average diameter microcapsules into ca. …

The development of poly(vinylidene fluoride) piezoelectric sensors for measuring peel stresses in adhesive joints
… angle studies, XPS analysis and 1800 peel and tapered double cantilever beam adhesion specimens. An acid etch using a mixture of acetic, phosphoric and nitric acids was found to greatly improve the bond strengths to an epoxy adhesive without reducing the piezoelectric activity of the film. The …

Autonomic healing of low-velocity impact damage in woven fiber-reinforced composites
… strength up to a threshold impact energy nearly double that of non-healing controls. Above this threshold impact energy, residual compressive strength was partially recovered to a degree that diminished with increasing impact energy. The work on self-healing 2D woven composites indicated that …

Multiscale characterization of carbon fiber-reinforced epoxy composites
Transverse cracking is an early form of damage in fiber-reinforced composite materials that can nucleate delamination, fiber breakage, and ultimate failure. Although many variables influence transverse cracking, little work has been done to characterize local and complex microstructural features …
