Effect of Stitching, Stitch Density, Stacking Sequences on Low-Velocity Edge Impact and Compression after Edge Impact (CAEI) Behavior of Stitched CFRP Laminates. [PDF]

Materials (Basel), 2022
Low-velocity edge impact and compression after edge impact (CAEI) behavior of stitched carbon-fiber-reinforced plastic (CFRP) laminates were experimentally investigated in the paper. Five groups, including three stacking sequences (P1, P2, P3) and two stitch densities (stitch space × stitch pitch is 10 mm × 10 mm and 15 mm × 15 mm) of stitched ...

Effect of Thickness and Stitch Density on Low-Velocity Impact and Compression After Impact Properties of Stitched Composite Laminates. [PDF]

Polymers (Basel)
In this work, experimental studies were conducted on the damage failure of laminated composite laminates under low-velocity impact and compressive failure behavior under compression after impact. The study primarily investigated the effects of stitch density, impact energy, and laminate thickness on the damage behavior of composite laminates.

Influence of Stitch Density on Tensile Properties of Polyethylene-Stitched Composite Laminates

Applied Sciences
Delamination in laminated composites originates from premature matrix cracking within the interlaminar region, ultimately leading to ply separation under indirect loading.

Influence of Stitch Density on Seam Strength in Cotton Fabrics [PDF]

AATCC Journal of Research
The goal of this paper was to investigate the influence of three different fabric thread densities per weft (10, 17, and 25 cm −1 ) as well as three different linear densities of weft threads (20, 30, and 50 Tex) on the seam strength of cotton fabrics. When measuring seam strength, the values

Embroidered Transmission Lines with Conductive Yarns: Challenges, Modeling, Fabrication, and Experimental Performance Assessment [PDF]

Sensors
This paper presents an enhanced measurement technique for evaluating embroidered transmission lines (TLs), based on a TL characterization method. The evaluation metric is the “pure” losses of the embroidered TL excluding mismatch losses.

Seam Strength Prediction for Different Stitch Types Considering Stitch Density of Cotton Woven Fabrics [PDF]

Textile & Leather Review, 2022
Seam strength is critical in achieving the proper and adequate quality seam, which eventually determines the overall quality of any garment. The target of this research was to investigate exactly how different stitch density affected seam strength for different stitch types.

Investigation into the tensile properties of ISO-401 double-thread chain-stitched glass-fibre composites

International Journal of Lightweight Materials and Manufacture, 2021
Interlaminar stitching has proven to be an effective through-thickness reinforcement technique for laminated composites but a major drawback is the negative effect it has on the in-plane tensile properties.
