“…The broadly distributed geometrical flaws and coarse yarns caused debonding and reduced stress concentration around sites of failure, therefore resulted in a lower strength decrease [11,12]. These results further confirmed that the stress concentration induced by a circular notch has little influence on the quasi-static tensile strength on 3D woven composites [10,11,12]. Figure 2 and 3 show the longitudinal strain distribution of two typical W-1 samples at different stress levels along with the image of the weave pattern.…”

“…The tensile fatigue properties of 3D woven composites were found to be better than 2D woven laminates [7], but decrease with increasing content of through-thickness reinforcement [6,8,9]. The fatigue sensitivity and the quasi-static tensile strength of the investigated 3D interlock composites was found to be uninfluenced by the presence of a central hole [10,11,12].…”

“…Much research has concentrated on the un-notched fatigue behaviour of 3D woven composites [7,6,8,9], with less research focused on the notched properties [10,11]. The tensile fatigue properties of 3D woven composites were found to be better than 2D woven laminates [7], but decrease with increasing content of through-thickness reinforcement [6,8,9].…”

“…Previous work on the fatigue damage progression characterisation for 3D woven composites was generally achieved by pausing the test and examining the specimen with X-ray computed micro-tomography [9] or optical microscopes [9,10]. Non-destructive testing equipment has been used to continuously monitor the fatigue damage in conventional laminated composites, such as acoustic emission [13,14,15], digital image correlation [14,16], and thermography [14,13,17,15].…”

Composite Structures, 131, Additional Information:• This paper was accepted for publication in the journal Compos- AbstractThis paper presents a comprehensive study on the open-hole quasi-static tensile and tension-tension fatigue behaviour of an orthogonal and an angle-interlock 3D woven carbon/epoxy composite. The full-field strain distribution during quasi-static tests was characterised using digital image correlation (DIC), and the fatigue damage behaviour was monitored using an infra-red camera. The notched tensile strength was less than 17% lower than the un-notched tensile strength and not very sensitive to the notch size. The fatigue specimens were loaded with maximum stress of about 60% of the ultimate failure stress and no complete fracture occurred after 5,000,000 cycles. The residual fatigue strength was also found to be similar to the quasi-static tensile strength in both weaves. The surface crack initiation and progression during fatigue loading was identified using thermoelastic stress analysis which revealed that the orthogonal weave had larger surface damage area than the angle-interlock weave.

“…In other words, 2D woven composites were found to be less notch sensitive (Naik et al 1990;Shembekar and Naik 1992). Replacing 2D with 3D woven composites helped in achieving further enhancement of the notched strength and fracture toughness, along the fibre direction, of composites as reported in (Cox et al 1996;Tsai et al 2000). The effect of the through-thickness binder in 3D woven composites was clearly observed as a dramatic decrease in the notch sensitivity of 3D woven composites and significant improvement of the fracture toughness and damage tolerance compared with those of 2D woven laminates.…”

Three dimensional (3D) woven composites have attracted the interest of academia and industry thanks to their damage tolerance characteristics and automated fabric manufacturing. Although much research has been conducted to investigate their out-of-plane "through thickness" properties, still their in-plane properties are not fully understood and rely on extensive experimentation. To date, the literature lacks an inclusive summary of the mechanical characterisation for 3D woven composites. Therefore, the objective of this paper is to provide a comprehensive review of the available research studies on 3D woven composites mechanical characterisation, with less emphasis on the outof-plane response, but an in-depth review of the in-plane response "un-notched vs. notched". The paper highlights the knowledge gap in the literature of 3D woven composites, suggesting opportunities for future research in this field and a room for improvement in utilising Non-Destructive Techniques (NDT), such as Digital Image Correlation (DIC), Acoustic Emission (AE) and X-ray Computed Tomography (CT), for observing damage initiation and evolution in 3D woven composites that could be used to calibrate and evaluate analytical and numerical models.
