Composites opportunities in eVTOLs

As eVTOL OEMs seek to advance program certification, production scale-up and lightweighting, AAM’s penetration into the composites market is moving on an upward trajectory.  


Electric vertical takeoff and landing (eVTOL) aircraft do not represent the first opportunity for composites to be applied in the mobility industry. The success of composites in the aerospace, automotive and marine end markets is no secret. But what makes the eVTOL industry as good as gold for the composites industry is the degree of penetration.

For instance, the Boeing 787, which acted as a torchbearer for the use of composites in aircraft, has ~50% of its structure made from composite materials. For the automotive industry, the numbers are significantly lower, with composite materials accounting for 8-12% of the vehicle’s weight in light vehicles. However, for eVTOLs, that same figure shoots up to an average of ~70% of the material mix, regardless of the maker.

Since most eVTOLs will be battery-powered, lightweighting is necessary in more than one way (i.e., making lighter components and also choosing designs that would require less components). On top of that, eVTOLs impose strict structural requirements. Because of this, composites are an obvious solution for eVTOL manufacturers.

From primary exterior structures like wings and fuselages to small secondary components like clips and brackets, composites will find applications in every cubic meter of an eVTOL. The image below highlights some major applications of composites in this aircraft type.

  Simonelli undertakes research to reuse composite materials Simonelli Group is currently undertaking a research and development project to reuse composite materials, that nowadays have a vast range of uses and applications thanks to their durability and longevity, but which are also very difficult to dispose of. The De-Manufacturing research project, developed by Delta srl and Simonelli Group, is part of the Marche Region’s Marche Applied Research Laboratory for Innovative Composites (MARLIC) platform in the context of ‘Sustainable manufacturing: eco-sustainability of products and processes for new materials and de-manufacturing’. “We are truly delighted to take an active part in this virtuous synergy, promoted and developed also within the MARLIC platform as advocates of a dual objective, to make a strong contribution to the transition towards a circular economy and to grow and develop the local industrial system,” says Fabio Ceccarani, Simonelli Group Managing Director. “The De-Manu

Unsaturated polyester (UP)  resin  is a low cost thermoset with excellent processing ability and  mechanical properties  that finds applications in fiber-reinforced polymer (FRP) materials. It also crosslinks readily in the presence of a catalyst such ketone peroxide, forming an even stronger and stiffer resin. Unfortunately, this also leads to lower  fracture toughness . Several methods to enhance the toughness of the cross-linked resin have been proposed; one such method involved blending with nano-fillers m

Revolutionizing Industries: Innovative Applications of Polymer Nanocomposites

Image
  In the dynamic realm of materials science, polymer nanocomposites have emerged as a revolutionary class of materials with unparalleled versatility and performance. From automotive engineering to biomedical technology, polymer nanocomposites are revolutionizing industries. This article explores the potential of polymer nanocomposites, highlighting their contributions to advancing materials science and supporting a sustainable future.1 What are Polymer Nanoparticles? Polymer nanoparticles, often termed nanofillers or nanoscale additives, are integral to polymer nanocomposites, imbuing them with exceptional properties. Ranging from 1 to 100 nanometers in diameter, these nanoparticles integrate into the polymer matrix, influencing mechanical strength, thermal conductivity, and electrical resistivity. Carbon-based nanoparticles like carbon nanotubes (CNTs) and graphene reinforce polymer matrices effectively, while clay nanoparticles enhance mechanical reinforcement and flame retardancy. M
