“…[57b] Additives may be added into the composite for various reasons, namely, to facilitate polymerization, reduce viscosity of the resin, stabilize the suspension, and to act as a coupling agent between the fiber and matrix. In another variation, a new layer of composite resin is added onto the build tray at the start of each layer to avoid sedimentation of fiber in the resin (Figure b). The fiber surfaces are treated in order to decrease the viscosity of resin to permit higher fiber concentration.…”

Additive manufacturing (AM) has brought about a revolution in the way we can manufacture complex products with customized features. AM has paved its way in the application areas ranging from aerospace, automotive, consumer to biomedical. AM of composites has attracted special attention due to its promise in improving, modifying, and diversifying the properties of generic materials through introducing reinforcements. This review provides a detailed landscape of fiber‐reinforced composites processed via AM techniques. Different AM processes, various material formulations, and strengths and drawbacks of AM methods are discussed. Emphasis is paid to AM techniques focusing on continuous fibers, as they hold the promise of becoming the next‐generation composite fabrication methodology. The article also tries to identify the potential of AM technology for fiber‐reinforced composites and delves into challenges facing the area.

This paper describes the uid mechanics of the slot-coating process in the context of rapid layered manufacturing. It has been conjectured that slot-coating would successfully address a number of common dif culties encountered in the formation of thin layers from a highly viscous brephotopolymer composite liquid. The objective of the present study was therefore the development of an engineering analysis tool to assist with the design of a slot-coating-based liquid layer formation mechanism for use as an integral part of a lithography-based rapid layered composite parts manufacturing (R LCM) system.In addition to an analytical model, the paper presents a numerical model based on a volume-ofuid (VOF ) algorithm. This algorithm allows (a) solution of non-steady-state problems, (b) tracking of the free surface of the uid undergoing large deformations and (c) easy modi cation of the model's domain to facilitate experimentation with coater geometry. R esults from a set of simulated experiments establish a relationship between the liquid-coat height and several design and process parameters.Physical examination of cross-sections of several test parts built on an R LCM prototype system in the authors' laboratory con rmed the ability of the new coater design to form solid layers of good quality, as predicted by the numerical simulations.

In the context of product development, the term rapid prototyping (RP) is widely used to describe technologies which create physical prototypes directly from digital data. Recently, this technology has become one of the fastest-growing methods of manufacturing parts. The paper provides brief notes on the creation of composites using RP methods, such as stereolithography, selective laser sintering or melting, laminated object modelling, fused deposition modelling or three-dimensional printing. The emphasis of this work is on the methodology of composite fabrication and the variety of materials used in these technologies.
