3D reinforced stitched carbon/epoxy laminates made by tailored fibre placement

Microstructure and tensile behavior of multiply needled C/SiC composite fabricated by chemical vapor infiltration

“…To improve the delamination resistance and save cost, a unique kind of multiply preform was developed by the means of the through-the-thickness needling technique. The multiply needled preforms have 3D architecture in real sense, which are similar to that of Novoltex preforms reported in literatures (Lacoste et al, 2002) but differ significantly from the multiply stitched preforms reported in literatures (Mattheij et al, 2000;Lomov et al, 2002). The multiply needled preforms consisted of unidirectional plies arranged in the desired orientations and short-chopped fiber fabrics.…”

Innovative tailored fiber placement technique for enhanced damage resistance in notched composite laminate

“…Mattheij et al [18] investigated the effect of through-the-thickness reinforcing of TFP preforms on in-plane and out-of-plane mechanical properties. In their work, TFP preforms made of carbon fiber were 3D reinforced with aramid, polybenzoxazol (PBO), polyethylene and polyester fibers and vacuum injected with epoxy resin.…”

Damage Tolerance Behaviour of Carbon Fibre Multi-axial Warp Knit Fabric Composites

“…Various researchers have presented results both agreeing and disagreeing with this conclusion. For example, Larsson [28] claimed better compressive properties with stitch density while Suh et al [29], Mattheij et al [30], and Mouritz [31] showed that the degradations of compressive properties with stitch density. All these references deal with overstitching but could be applicable to the present study.…”
