Abstract

Composite materials have now been adopted in a wide range of applications, primarily due to their weight-saving potential. Overwhelmingly so, these materials have been used in laminated or monolithic structural components. Moving towards lattice configurations, in which the structure is formed from a network of connected members, can offer unparalleled structural efficiencies. From a structural standpoint, composites are ideal materials for the formation of lattice structures as their anisotropic properties can be exploited within the mainly uniaxially stressed members. However, from a manufacturing standpoint, they present a range of challenges that, so far, has largely limited their application within industry. Within this field, there is now a wide range of different approaches to creating composite lattice structures that are under development. This paper organises and assesses the current work on these technologies, with the core focus being on their associated manufacturing methodologies. Three main classifications are identified based on the geometry and intended use of the structure, and progress made in each is highlighted alongside key remaining hurdles to widespread implementation.
