A comparison of fabric structures for carbon fiber reinforced composite: Laminated and orthogonal woven structures

Abstract

In this research, orthogonal structure carbon fiber reinforced composite was developed and its properties were compared with those of laminated structure composite. To solve the problem of yarn damage caused by friction during the weaving process, a custom-built weaving device was build up. Compression and vacuum-assisted resin infusion molding (VARIM) techniques were selected and compared. It was found that fiber geometries could be well retained using the later one. The orthogonal and laminated composites prepared by the VARIM technique with the fiber volume fraction were 32.76% and 38.64%, respectively. Flexure and impact tests were performed to evaluate the properties of laminated and orthogonal composites. The results show that orthogonal composite exhibits superior properties in the warp and weft directions. In addition, due to its straight yarn path and insertion of carbon fiber in the through-thickness direction, orthogonal fabric reinforced composite exhibits an improved bending strength over composites reinforced by laminated plain woven fabric, although the fiber volume fraction of orthogonal composite is much lower than that of laminated composite. The findings indicate that orthogonal structure composite provides profound guiding significance for product development and application of carbon fiber composite.

Improvement of interfacial adhesion of CuO nanostructured carbon fiber reinforced polymer composites

“…The correct proportion of the fiber content should be determined because several studies have expressed that it is one of the most important factors in enhancing the mechanical properties of fiber reinforced composites. [ 28,29 ] The ASTM D2584 standard is typically used to calculate the fiber volume proportion as follows in Equation () [ 30 ] . Where, denotes the volume fraction of the fiber, denotes fiber density, denotes matrix density, denotes weight of the fiber, and denotes weight of the matrix. When it comes to textiles, the spacing between the yarns of the textile pattern determines the total fiber volume proportion.…”

Effect of woven structure and aramid binder yarn on the flexural performance of carbon/aramid fiber hybrid three‐dimensional woven composites

“…Many technologies have been used to overcome this disadvantage, such as improving the combined strength between fiber and resin [1][2][3][4] ; introducing fiber or yarns in the throughthickness direction of laminated structures, such as stitching, [5,6] Z-pinning, [7] and tufting, [8] whereas threedimensional (3D) woven textile structures with three groups of yarns (warp, weft, and binder yarns in three linear perpendicular directions) have attracted much attention for decades as reinforcement structures to improve composite through-thickness strength. [9][10][11][12][13][14] Based on the internal yarn interlacement, 3D woven structures could be classified into many types, such as orthogonal interlock, angle-interlock, layer-to-layer, and multilayer. [15,16] Many researchers have studied the outof-plane mechanical performance of FRP composites with various woven structures.…”

Aligned carbon nanotube composite belts stitching of laminated composites for enhanced fracture toughness and enriched functionalities

“…However, the relatively poor interlaminar strength, toughness, and conductivity of CFRPs, which was caused by the weak and insulating resin-rich regions at ply-ply interfaces, greatly limit their light-weighting efficiency. In the last few decades, several interlaminar strengthening methods, such as interlayer toughening, [1][2][3] z-pinning, [4][5][6] stitching, [7][8][9] as well as 3D weaving, [10][11][12] have been developed. Although most of these methods are effective in enhancing the interlaminar mechanical properties, they usually have a negative effect on in-plane mechanical performance because of the fiber damage, fiber misalignment as well as in-plane fiber volume loss.…”
