Overview
The white paper discusses the role of hybrid cross-car beams in the automotive industry, particularly in the context of increasing pressure on original equipment manufacturers (OEMs) to reduce vehicle emissions and meet stringent CO₂ targets. Envalior's technical expert, Ron Krotwaar, highlights how these hybrid solutions, which combine thin-walled metal inserts with high-modulus thermoplastics, enable significant weight savings of 20–30% compared to traditional steel components. This weight reduction is achieved without compromising safety or structural integrity, particularly in crash management and torsional rigidity.
The adoption of hybrid technologies also addresses rising raw material costs and supply chain volatility. By reducing overall metal content, OEMs can decrease their reliance on materials susceptible to geopolitical disruptions, such as steel and aluminum. The shift towards engineered thermoplastics, which can often be sourced regionally, allows for more stable pricing and better management of material cost fluctuations. Additionally, hybrid beams facilitate lower-cost tooling, faster production cycles, and the elimination of post-processing steps, contributing to more predictable manufacturing costs.
Sustainability is a key focus, with hybrid beams supporting circular economy goals. Their lightweight nature leads to reduced tailpipe and lifecycle emissions, while the integration of functions minimizes the number of parts and assembly operations, lowering energy consumption during production. Envalior’s materials portfolio includes bio-based and recycled-content polyamides, further enhancing sustainability efforts.
In the context of increasing vehicle electrification, hybrid cross-car beams offer advantages such as tailored stiffness-to-weight ratios, integrated channels for wiring and mounts, superior noise, vibration, and harshness (NVH) performance, and adaptability for modular designs. Envalior’s approach combines material innovation with comprehensive development support, enabling faster concept-to-production timelines, which is crucial for OEMs navigating a complex global market.
