Dynamic Interlaminar Fracture Toughness of CFRP Composite Laminates

1996
New experimental techniques were devised for determining dynamic mode I, moode II and mixed mode interlaminar fracture toughness of CFRP laminates. Up to the impact velocity of 10–20m/s, rate effects on interlaminar fracture toughness of each mode were investigated and compared with the quasi static results.

The toughness contribution of bamboo node to the Mode I interlaminar fracture toughness of bamboo

Wood Science and Technology, 2013
Bamboo is a kind of biological composite reinforced by unidirectional long fibers. The cleavage strength along grain of bamboo internode is low; however, the existence of bamboo node can hinder the propagation of interlaminar crack to make up for the defect of weak opening mode fracture toughness along interlamination.

Nanowire reinforcement of woven composites for enhancing interlaminar fracture toughness

Journal of Sandwich Structures & Materials, 2016
A novel technique to improve the Mode I and Mode II interlaminar fracture toughness of woven carbon-fiber polymer matrix composite face sheets using zinc oxide nanowires is proposed. Zinc oxide nanowires are directionally synthesized on dry carbon fabrics that are used to manufacture the laminate.

Effect of Fiber Coatings on Interlaminar Fracture Toughness of Composites

1987
A candidate approach for improving the fracture toughness of graphite fiber epoxy composites was investigated in which coatings of tough epoxy based adhesives were applied to the graphite fibers and subsequently overcoated with a 350°F (177°C) service epoxy laminating resin. Composites were fabricated from the coated fiber/epoxy matrix prepreg and from

Interlaminar fracture toughness of graphite fiber-reinforced polyimide composites

Mechanics of Composite Materials, 1995
The present study has proved the effectiveness of the application of viscoelastic polymers with increased fracture toughness to graphite/polyimide composites interlaminar fracture toughness improvement. Thermoplastic polysulphone film and thermoresistant structural adhesive have proved to be inherently more effective for composites' delamination ...
