The triaxial woven fabric is known for their light weight and isotropy of mechanical properties. However, researches that using it as reinforcement to form different structural composites were rarely mentioned. Here, we found that the effect of the triaxial woven fabric can be almost equivalent to the unidirectional fabric in flexural strength (99.18%) when it was added as a reinforcing material into the unidirectional fabric composites even though the weight of triaxial woven fabric has only a third of unidirectional fabric. Moreover, the effects and mechanisms are quite different when changing the position of the triaxial woven fabric in the composites. The damage modes of composites when triaxial woven fabric in different stacking sequences were summarized and the resin blocks model from triaxial woven fabric composites was presented in this paper.

“…14 Tensile experiments from different directions show that the tensile modulus of TWF in the weakest direction was increased more than two times compared with traditional woven fabric, and the bursting strength of TWF was significantly improved. 15 The research on triaxial woven fabric composites (TWFCs) mainly focuses on their mechanical properties 2,[16][17][18][19][20][21] and model analysis. [22][23][24][25][26] Carbon fiber has drawn attention because of its characteristics of high strength and modulus and, moreover, it has light specific gravity.…”

Warp control devices and tension for triaxial woven fabric with carbon fiber

In the weaving process of triaxial woven fabric (TWF), warp yarns need to be moved in different directions at each weaving step, which makes it difficult to control the warp tension. Furthermore, the friction of carbon fiber will lead to fuzzing and fracture of yarns in the manufacturing process, which brings challenges to the weaving of TWF with carbon fiber. Here, we have designed a warp control system for weaving TWF with carbon fiber. It includes a let-off mechanism and fabric winding device, which have been demonstrated to realize the continuous weaving of TWF with different specifications of carbon fiber (1k, 3k, 6k, 12k, 24k). The let-off mechanism meets the needs of moving the warp at each weaving step and keeping the carbon fiber in its the original shape. The compensation length ([Formula: see text]) and warp tension during interweaving could be adjusted by the polyester filament and the number of weights ([Formula: see text]), respectively. The fabric winding device can take up the formed fabric by controlling the stepping motor. Moreover, the relationships between the control parameters of the stepping motor ([Formula: see text]) and the width of carbon fiber ([Formula: see text]) have been established.

Inconel 718 is a challenging alloy to machine, commonly employed in the aeronautic and energy industries. There is a continual need to enhance our understanding of its cutting processes to improve its machining applications. This research presents an in situ analysis of the kinematic and thermal elds behaviour of a serrated chip, during orthogonal cutting in the primary shear zone. This study involves a speci c self-designed optical system enabling the simultaneous acquisition of both a visible high-speed CCD and an infrared cameras. A particular attention is brought to evaluate the accuracy of the whole optical system to measure the thermomechanical elds in the unfavourable peculiar cutting conditions among such: high strain rates, texture evolution, strong thermal gradients, very narrow observation window... The description of the digital image correlation technic within the visible range and the infrared images post-processing are both affronted, and their limitations exposed. To conclude, a deeper characterisation of the primary shear zone shape is done from the kinematic and the thermal point of views showing that, at least under the employed cutting conditions and for Inconel 718 alloy, the primary shear zone width exhibits no thickness despite the literature.
