From the Sector

Autoneum’s sustainable, textile and lightweight Propylat technology reduces both interior and exterior noise of vehicles. Propylat was originally developed by Borgers Automotive, which was acquired by Autoneum in April 2023. The versatile technology is characterized by a flexible material composition of natural and synthetic fibers with a high recycled content and contributes to significant waste reduction thanks to its complete vertical integration. In addition, the fully recyclable technology variant Propylat PET is now part of the sustainability label Autoneum Pure.

The ongoing electrification of mobility as well as increasingly strict regulatory requirements for vehicle performance in terms of sustainability and acoustics are presenting new challenges to car manufacturers worldwide. With Propylat, Autoneum now offers another lightweight, fiber-based and versatile technology whose sound-insulating and -absorbing properties as well as high content of recycled materials help customers address these challenges. Propylat-based products not only contribute to reducing pass-by noise and improving driver comfort, but they are also up to 50 percent lighter than equivalent plastic alternatives; this results in a lower vehicle weight and, consequently, less fuel and energy consumption as well as lower CO2 emissions.

Autoneum's innovative Propylat technology consists of a mixture of recycled synthetic and natural fibers – the latter include cotton, jute, flax or hemp, for example – that are consolidated using thermoplastic binding fibers without adding any further chemical binders. Thanks to the flexible fiber composition and the variable density and thickness of the porous material, the properties of the respective Propylat variant, for example with regards to acoustic performance, can be tailored to individual customer requirements. This allows for a versatile application of the technology in a variety of interior and exterior components such as wheelhouse outer liners, trunk trim, underbody systems and carpets. For instance, Propylat-based wheelhouse outer liners significantly reduce rolling noise both inside and outside the vehicle while at the same time offering optimum protection against stone chipping and spray water.

In terms of sustainability, Propylat always contains a high proportion of recycled fibers – up to 100% in some variants – and can be manufactured with zero waste. Thanks to the full vertical integration of Propylat and Autoneum’s extensive expertise in recycling processes, the technology also contributes to a further significant reduction in production waste. Moreover, the Propylat PET technology variant, which consists of 100% PET, of which up to 70% are recycled fibers, is fully recyclable at the end of product life. For this reason, Propylat PET has been selected for Autoneum Pure – the Company’s sustainability label for technologies with excellent environmental performance throughout the product life cycle – where it will replace the current Mono-Liner technology going forward.

Propylat-based components are currently available in Europe, North America and China.

Catering to the acoustic requirements of electric vehicles, Autoneum has extended its concepts for noise-reducing engine encapsulations to new applications related to electric drives. Hybrid-Acoustics PET and the foam-based alternatives Hybrid-Acoustics FLEX and Fit FLEX ensure optimum noise protection in e-cars and thus improve driving comfort. All three technologies are characterized by a high acoustic performance tailored to specific customer needs and zero waste production.

Disturbing noises such as the high-frequency sounds of e-motors and other electric devices or the whining noise of the gearbox are posing new acoustic challenges for vehicle manufacturers worldwide. Anticipating the increasing demand for sound-reducing components in both the front and the rear of e-cars early on, Autoneum has expanded its technologies for noise protection in the engine bay to new tailor-made applications for electric vehicles.

With the fibrous technology Hybrid-Acoustics PET and the two foam alternatives Hybrid-Acoustics FLEX and Fit FLEX, the Company offers three standardized technologies that reduce noise directly at the source, thereby improving driver comfort. All three technologies are produced waste-free and their adaptive capacity to different sizes and shapes allows for a broad spectrum of uses in electric vehicles: from e-motor encapsulations to the reduction of noise and vibration of inverters, gearbox, pumps and compressors. By offering both fibrous and foam-based variants, Autoneum is able to flexibly cater to individual customer needs and preferences with regard to material, acoustic concept, sustainability and costs.

In terms of sustainable noise protection in the engine bay, Autoneum’s patented innovation Hybrid-
Acoustics PET sets the tone: it is made of 100 percent PET with up to 50 percent recycled fibers; cut-offs in production are reclaimed, processed and reused and the material can be fully recycled at the end of product life. The unique textile technology, which is part of the Company’s sustainability label Autoneum Pure, is particularly suited to attenuating high-frequency sounds of the electric drive unit and offers the optimum balance of absorption and insulation. Moreover, components made of Hybrid-Acoustics PET are up to 40 percent lighter compared to standard insulators.

To accommodate the differing preferences of vehicle manufacturers, Autoneum has complemented its lightweight textile technology with two foam-based alternatives. Since the foam is injected in both technologies, no waste is generated during production either. Hybrid-Acoustics FLEX is based on the same acoustic concept as Hybrid-Acoustics PET, but the decoupler is made of foam instead of felt. Autoneum’s Fit FLEX, on the other hand, combines the foam decoupler with an injection molded heavy layer. Thanks to the high geometrical adaptability of foam to even complex shapes, both technologies offer outstanding acoustic performance in the insulation of e-motors and other noise sources in electric vehicles. Furthermore, the absorbing or insulating acoustic quality of the foam can be flexibly tuned to specific customer needs.

• A springboard for entrepreneurs in the composites industry

In a few years, JEC Composites Startup Booster has became a reference for entrepreneurship in the composites industry worldwide. Each year before JEC World, among the startups that submitted their application, 20 of them are selected. 20 finalists from all over the world who will join the leading composites trade show to pitch their project on stage before a panel of expert judges.

This competition is a unique opportunity to network and shine a light on what will be the future of the composites industry so save the date: the two pitches sessions will happen on May 3rd, and the winners will be named on May, 4th at 2.45 pm at JEC World 2022 in Paris as well as online on JEC World Connect platform. This year’s competition is sponsored by Airbus & Mercedes-Benz (Main Innovation Partners) as well as Magna Exteriors (Innovation Partner).

Launched in 2017, Startup Booster has been organized in three different regions (Europe, USA and Asia) and has already fostered the emergence of 500+ innovative projects from 50+ countries, 80 finalists and 30 winners, including Arevo, Continuous Composites, ComPair, Fortify and Vartega…
This challenge not only represents an opportunity to the winners of the trophy but to all the parts involved: participants, jury, official partners and the worldwide audience of JEC World. It brings the entire composites value chain together, creating future business opportunities.

The 20 finalists are divided into two categories:
• Process, Manufacturing & Equipment
• Materials & Products

The jury includes representatives from major manufacturers and investors:
Jelle BLOEMHOF, Head of Manufacturing Technologies of Composite, Airbus
