Short electrospun polymeric nanofibers reinforced polyimide nanocomposites

Nanofibre bridging as a toughening mechanism in carbon/epoxy composite laminates interleaved with electrospun polyamide nanofibrous veils

“…PAN [8], PCL [2], P(St-coGMA) [11,12], PI [13], PA 6 [14e16] and PA 6.6 [17e22]. Regular fibrous veils, with a larger diameter of the fibres compared to nanofibrous veils, have also been investigated to study the interlaminar toughening effect [23e26].…”

Electrospun nanofiber reinforced all-organic PVDF/PI tough composites and their dielectric permittivity

“…Previous work found that the electrospun PI nanofibers possessed excellent mechanical strength [13], superior thermal stability [14], and super high toughness [13], which made them excellent candidates as reinforcements [15,16] and the layer-by-layer hot pressing can improve the uniformity and reduce the porosity of polymer-based composites [17][18][19]. Therefore, in this work, we choose high performance electrospun copolyimide (co-PI) nanofibers as reinforcement and high dielectric performance PVDF as matrix to prepare nanofiber reinforced all-organic composites.…”

Electrospun nanofibers as reinforcement for composite laminates materials – A review

“…• resin reinforcement [23,60,[87][88][89][90][91][92][93][94], detected by several authors, using a different type of polymers. In [94] it is demonstrated that using an hybrid electrospinning-electrospraying method (electrospraying uses polymers with much shorter chains which end deposited as particles rather than fibers), a resin containing 0.13% weight content of fiber was 700% stronger, 250% stiffer, and more ductile than the non-modified one.…”

“…The main issues with the use of CNT and CNF are linked to health dangerousness [85] and difficulties in mixing and homogenizing with the matrix [86]. Authors considered out of the scope of this literature, and therefore did not treat, studies on nanofibers embedded in pure matrix [60,[87][88][89][90][91][92][93][94], on the single nanofiber [95][96][97][98], and on numerical simulations of nanomodified composites [65,[99][100][101][102].…”
