During a crash event, CBS™ structural inserts provide a desirable combination of section stability, load path transition, multi-axis load management, and energy absorption. The optimization of body sections with weight and space saving CBS™ parts allows for an efficient body design, minimizing the deformation of the structure resulting in reduced intrusion into the vehicle’s passenger or battery space.
Composite Body Solutions (CBS™)
CBS™ for optimizing strength, stiffness and weight
CBS™ is a solution combining a unique foaming adhesive with a highly engineered thermoplastic or thermoset structural carrier.
What is CBS?
Structural reinforcement for improved performance, mass, process and cost optimization
Our CBS™ technologies combine highly engineered heat activated structural adhesive material (also known as structural foams) with a customized thermoplastic carrier. CBS™ enables lightweight but strong structural applications for both current and future-ready applications, such as battery protection in electric vehicles (EV).
The L&L Products team uses its proven expertise with advanced CAD/CAE simulation to design a three-dimensional engineered part. The result is a structural insert that is dry-to-the-touch and ready to assemble into the body structure prior to cavity closure and e-coating. Our foaming structural adhesives allow for e-coat flow and coverage of the cavity prior to structural adhesive foaming in the e-coat bake oven.
L&L introduced Composite Body Solutions (CBS™) to the transportation industry over 20 years ago as an innovative solution for body in white reinforcement. It is still the clear global market leader. L&L works closely with our customers to provide engineered solutions that reduce vehicle weight, increase stiffness for NVH applications, improve safety and crashworthiness and improve the fatigue life of vehicles.
Composite Body Solutions (CBS™) enable lightweight body structures while enhancing overall performance of the application. With early involvement in the development, the lightweight cost can be neutral (same cost as a traditional metallic structure) or even negative (reduced cost compared to a traditional metallic structure). This is achieved by enhancing existing geometries, replacing less effective parts, and using synergies between materials. CBS™ can also reduce the number of metallic parts used, thereby, reducing weight.
L&L CBS™ technologies can enable a cost effective, robust reinforcement solution that brings extensive engineering knowledge, for lightweight Body in White (BIW) optimization.
... for stability of cross sections
... tolerances that exist due to the complexity of automotive assembly is handled by incorporating the ability of the adhesive to foam.
