Composites end markets: Automotive (2023)


As the automotive industry focuses on electrification, new opportunities exist for composites to lightweight vehicle components and protect the newer, larger batteries on battery-electric vehicles (BEV). Shown here, the BMW iX BEV features a multi-material composites-intensive frame.

Low-volume, high-end vehicles and motorsports have made frequent use of composite materials for years, favoring continuous carbon fiber materials for high-performance, lightweight vehicles.

The more cost-sensitive market for mid- and high-volume production vehicles has been slower to adopt composites. However, a steady, incremental increase has been seen in the use of continuous glass fiber-reinforced polymers (GFRP) in applications such as leaf springs, as well as sheet molding compound (SMC) for applications like body panels and frames, bulk molding compound (BMC) for housings and support structures and injection molded thermoplastics for bumper frames, lift gates and seat structures.

More recently, new opportunities for composites use on commercial mid- and high-volume vehicles have come about as the automotive industry ramps up production of battery-electric vehicles (BEV). According to the U.S. Department of Energy (DOE), sale of plug-in vehicles — including BEVs and hybrid electric vehicles — rose nearly double in 2021 compared to 2020. Batteries in BEV are heavier than internal combustion engine (ICE) vehicle batteries, necessitating lightweighting elsewhere in the vehicle to maximize the vehicle’s range and efficiency.

 

Battery enclosures Electric vehicle (EV) battery enclosures — covers and trays that hold and protect the frames and battery cells within an EV — are perhaps the area with the most opportunity for composites in automotive right now, led by the need for OEMs to reduce the mass of the overall battery pack. As reported by CW in Part 1 of a two-part 2022 feature on composite enclosures, empty metallic battery enclosures are said to add 110-160 kilograms to vehicle mass even before they’re loaded, making them the heaviest component on BEVs — presenting an opportunity for lighter weight composite materials.

  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
