Composite Body Solutions™ (CBS™)
CBS™ for Optimizing Strength, Stiffness and Weight
What is CBS™?
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.
CBS™ Optimizes Strength, Stiffness and Weight
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.

Expandable Adhesive
Tolerances that exist due to the complexity of automotive assembly are handled by incorporating the ability of the adhesive to foam.
Robust Assessment
The models developed by our experienced CAD / CAE design teams provide high predictbility. Globally, we use 8 CAE tools, 3 top CAD design tools, and complete comprehensive prototyping and testing / validating of our solutions.
Potential Applications
Main CBS™ Attributes Are:
- Load path management
- Section integrity
- Light-weight potential
- Improved stiffness
- Increased durability
- Reduced implementation timing
- No impact to the body shop
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.
CBS™ reinforcements can eliminate localized durability problems, such as metal fatigue, by increasing overall stiffness and distributing loads more effectively across the structure.
Improved noise, vibration, and harshness (NVH) performance is also commonly achieved when our CBS™ structural reinforcement technology is integrated into the body structure. Again, careful engineering analysis allows development and location of optimal solutions to optimize vehicle ride and handling characteristics.
The design flexibility of CBS™ parts allows to simplify the manufacturing process in areas of complex or difficult-to-access assembly conditions. For example, using CBS™ for doors and closures can offer weight savings and stiffness gain, but can also help to simplify door manufacture if taken into consideration already in the design process.
