Full recovery of interfacial bond strength after complete fiber/matrix debonding is achieved with a microencapsulated solvent-based healing chemistry. The surface of a glass fiber is functionalized with microcapsules containing varying concentrations of reactive epoxy resin and ethyl phenylacetate (EPA) solvent. Microbond specimens consisting of a single fiber and a microdroplet of epoxy are te...

We present the implementation of aligned carbon nanotubes (CNTs) as a method to enhance properties of traditional advanced composites. The hybrid composites are 3-dimensional architectures of aligned CNTs, and existing advanced fibers and polymeric resins creating nanoengineered composites. Our work to date has focused on interlaminar strength and toughness, and electrical and thermal conductiv...

The influence of nanoclay on the impact damage resistance of glass fiber–epoxy composites has been investigated using high-velocity repeated ice impact tests. The incorporation of nanoclay into epoxy enhances the impact resistance of the composites. The impact of ice is a realistic scenario for composite structures such as aircraft fuselages, wing skins and fan blades and it is not a completely...

The creep and dynamic mechanical behavior of natural fiber/epoxy composites using functionalized multiwalled carbon nanotubes (MWCNTs) modified matrix were investigated. 0.4 wt% of MWCNTs functionalized with carboxylic acid groups (MWCNTs-COOH) were dispersed in epoxy and three-phase multiscale hybrid composites were processed by hot press. Natural fiber/epoxy two-phase composites without MWCNT...

The combined effect of the use of carbon fiber and seawater and the molecular structure on the tribological behavior of various polymer materials under natural seawater lubrication was investigated. After the investigation, the wear morphology of the contact surface was observed by a laser scanning confocal microscope, and the texture of the wear scars and tracks were presented in 3D profiles. ...

The improvement of electrical conductivity of carbon-fiber reinforced plastics (CFRP) has been investigated by conductive silver nano-particles coating for the purpose of aircraft lightning protection. Silver nano-particles in colloid were sprayed on the surface of carbon fibers, which were then impregnated by epoxy resin to form a CFRP specimen. Electrical resistance was measured by contact re...

This study is focused on the influence of a modified matrix glass fiber reinforced laminates, which inherently have different material properties than carbon composites. For this we green epoxy resin with 2.5wt% based fillers (synthesized graphene nanopellets, and milled recycled fibres), were subsequently applied to multifilaments, vacuum cured obtain fiber/epoxy UD laminates. The prepared sam...
