“…Comparing the ultimate compressive load in the case of the baseline specimens (see Table 2) clearly reflects the effect of crimp in 2D and 3D woven composites. This crimp effect has been the scope of many research studies in the literature [9,11,28,[38][39][40], and it confirms the trend observed in this study. NCF with the least waviness exhibits the maximum compressive strength (see Table 2), followed by the 2D-PW, then the ORT-TW and the ORT-PW withstanding the least compressive load to failure.…”

This paper investigates the effect of the fabric architecture and the z-binding yarns on the compression after multiple impacts behavior of composites. Four fiber architectures are investigated: non-crimp fabric (NCF), 2D plain weave (2D-PW), 3D orthogonal plain (ORT-PW) and twill (ORT-TW) weave. The specimens were subjected to single and multiple low-velocity impacts at different locations with the same energy level (15 J). Non-destructive techniques including ultrasonic C-scanning, X-ray CT and Digital Image Correlation (DIC) are employed to quantitatively analyze and capture the Barely Visible Impact Damage (BVID) induced in the specimens. Although the absorbed energy was approximately the same, damage was the least in 3D woven architectures. In the case of compression after impact, 3D woven composites demonstrated a progressive damage behavior with the highest residual strength (~92%) while 2D plain weave and NCF specimens showed suddenly catastrophic damage and the residual strength of~65% and~55% respectively.

“…There is general acceptance that the current practice of designing a damage tolerant structure is to take advantage of composite material heterogeneity and to configure the material such that it will withstand certain types of damage and will naturally arrest their propagation; 3D fibre architectures [16][17][18] and resins modified with nano particles [19][20][21][22] have been used in that effort. Yet, this is a passive approach and for this reason it is subject to its own limitations.…”

Empirical or semi-empirical design methodologies at the macroscopic scale (structural level) can be supported and justified only by a fundamental understanding at the lower (microscopic) size scale through the physical model. Today structural integrity (SI) is thought as the optimisation of microstructure by controlling processing coupled with intelligent manufacturing of the material: to maximise mechanical performance and ensure reliability of the large scale structure; and to avoid calamity and misfortune. SI analysis provides quantitative input to the formulation of an appropriately balanced response to the problem. This article demonstrates that at the heart of the matter are those mechanisms of crack nucleation and growth that affect the structural integrity of the material: microscopic cracking events that are usually too small to observe and viewed only by microscopy.

“…For woven composites, literatures about ERM in both plain and 3D woven structures have been reported and the effects of the structures on sensing property have been studied through experimental method. 20,21 However, the results of ERM method usually reflect a vague relation between the location of geometric change and resistive property. This is caused by the CFs in the FRPC materials, such as prepregs, that are arranged into an entirety, which makes the whole structure to become a resistor network.…”

“…Among various woven fabric, 3D orthogonal weaving fabric (3DOWF) has a good property in anti-delamination and is studied by a lot of researcher in both mechanical and electrical performance. 20,26 In this work, the 3DOWF was chosen to reinforce the composite in a practical hat-shaped structure, which is a common structure in vehicle frame, and consisted two types of fibers, i.e. carbon fibers (CFs) and Kevlar fibers (KFs).…”

An investigation into self-sensing property of hat-shaped 3D orthogonal woven composite under bending test

In this paper, the influence of damage and deformation on the electrical property of carbon fibers in the hat-shaped 3D orthogonal woven fabric-reinforced composite structure is studied. A method of producing parallel sensor arrays was proposed, in which the warp yarns made of carbon fibers were separated by isolated Kevlar fibers as weft yarns and Z-yarns. The sensor array unitized the self-sensing property of carbon fiber and could detect the damage and deformation distribution along the transverse direction of the composite under bending tests. Both the experiments and simulations had been conducted to analyze the mechanical and electrical responses of the carbon fiber array. By comparing the experimental results and simulation data, the method was validated and the influences of damage and deformation distribution on the resistance variation of carbon fibers were revealed.
