Laminated composites and methods of making the same

摘要

The present disclosure relates to a fibrous veil and methods of making the same. The fibrous veil includes a base having a plurality of fibers, each of the plurality of fibers having an average diameter ranging from about 7,000 nm to about 9,000 nm. Graphite nano-platelets are attached to at least some of the plurality of fibers without a polymeric binder.

1. A fibrous veil, comprising:
a base including a plurality of fibers, each of the plurality of fibers having an average diameter ranging from about 7,000 nm to about 9,000 nm; and graphite nano-platelets attached to at least some of the plurality of fibers without a polymeric binder, the graphite nano-platelets being a mixture of exfoliated graphite nano-platelets, the mixture having a 1:1 weight ratio of graphite nano-platelets having an average diameter of about 5 microns and graphite nano-platelets having an average diameter of about 15 microns, the average diameter of an individual graphite nano-platelet being measured across a lateral dimension of the individual graphite nano-platelet; wherein when the fibrous veil is to be laminated to an interface formed between adjacent prepregs of a laminated composite, the laminated composite exhibits an increase in at least one of a maximum load, an energy to maximum load, and an energy to penetration.
