“…The damage initiation force for 3D noninterlaced stitched composite is lower than for the 2D unstitched woven composite due to weak resin-rich regions around the stitch loops. Densely stitched composite with more stitched-induced matrix cracks upon impact loading is due to the presence of weak resin-rich pockets around the stitching yarns [77][78][79][80]. The noncrimp stitched carbon fabric composite shows a quasi-isotropic behavior, while 2D woven composite demonstrated an anisotropic behavior.…”

E-glass three dimensional (3D) stitched preform composites have been developed for several industrial applications due to their high mechanical performance and damage tolerance properties. Although some in-plane properties of the stitched E-glass composite structure are slightly lower than in laminated composite, its mode-I delamination failure is improved. This was achieved by using the out-of-plane directional stitched fibers. Recently, some nanoparticles as single-walled nanotubes (SWNT) or multiwalled nanotubes (MWNT) or nanofibers (NF) were added to the glass fabric structure or stitched preform during consolidation process. This further enhances the thermo-mechanical impact properties of the E-glass fiber composites.

“…Conversely, in‐plane tensile and shear properties of the stitched composites were slightly reduced but their through‐the‐thickness directional properties were improved . The failure strength for NCF composite was inferior compared to 2D woven composite because of complex heterogeneous interphase behavior in the stitch loops . The fractured areas of four directional stitched woven composite was lower compared to the base 2D woven composite .…”

In‐plane response of para‐aramid/phenolic nanostitched and nanoprepreg 3D composites under tensile loading

The tensile properties of nanostitched and nanoprepreg three dimensional para‐aramid/phenolic composites were studied. The tensile responses of para‐aramid/phenolic composites showed three regions as initial interfiber friction, crimp exchange, and yarn extension regions. Their tensile moduli in each region were defined. It was obtained that stitching and multiwall carbon nanotubes slightly increased the tensile strength of all stitched and stitched/nano composites. Tensile failure on all stitched structure showed brittle matrix and multiple ductile filament breakages in yarn after angular deformation in composite surface layers as well as local restricted delamination. Failure mechanism of carbon stitched composite was interestingly different compared to para‐aramid stitched composite in where carbon stitching yarn was failed in the loop section. It was pulled out thickness direction of the composite and caused large local opening between layers. POLYM. COMPOS., 40:1275–1286, 2019. © 2018 Society of Plastics Engineers

“…19 However, stitching caused weak resin-rich regions near the stitching loop section and affected the damage initiation force. [20][21][22] It was claimed that the exural strength and modulus of the 3D multiaxis composite were hardly lower than those of the 3D composite because of the bias bers. 23,24 In single-wall carbon nanotubes (SWCNTs) and multiwall carbon nanotubes (MWCNTs), sampling, size, surface area/ volume, density, crystallinity and purity are considered important material parameters.…”
