“…200,201,207 Coupled flexural torsional analysis with consideration of warping effects for thin-walled VSC beams are presented recently. 109,219 Günay and Timarci 220 investigated closed cross-section thin-walled beams considering warping effects as well as the variable stiffness along the length. The linear variation of the fiber, modeled using the CTS process, is considered.…”

The functional advantages of tailored stiffness, often seen in nature, are also utilized in composite structures. Advancements in the multiaxis tow placement and automated fiber placement (AFP) machines led to the development of variable angle tow (VAT) composites, also referred further as variable stiffness composites (VSC). These composites are shown to effectively enhance the stress distribution and buckling load capacity of structures with greater flexibility on the design space. This review systematically presents the status of recent research on the topic of VSCs. Various manufacturing techniques of VSC are discussed; constraints and the defects associated with the manufacturing processes are enlisted. The review highlights the optimization studies based on the fiber profile and macro-scale stiffness invariants. Several studies existing in the domain of buckling, vibration, and aeroelastic tailoring of angle tow composites are summarized to connect the important aspects of analysis and present a holistic approach for future studies in this area.

“…Production of variable stiffness layers with curvilinear fibers is not discussed in this paper, methods such as automated fiber placement (AFP), automated tape laying (ATL), Continuous tow shearing method [15] can be used for this purpose. It is assumed that the variable stiffness layers do not have any gap or overlap and the curved fibers are placed by shifting the fiber path along 𝜂 axis.…”

A novel method for production of variable stiffness woven fabrics with curved advanced fibers is presented. A scalable concept design is introduced. Several variable stiffness fabrics are woven by the prototype loom. The weaving process and woven fabrics are examined. Two distinct regions of the fabric which are showing different behaviors are observed. Based on the two regions identified the curved fibers of the woven fabric are simplified and modeled as a three-dimensional unit mesh. Geometry variation of the curved fibers and stiffness variation of the woven fabrics are discussed for these two distinct regions by using the developed model.
