Structural Reinforcements

Composite Body Solutions (L&L CBS)

L&L’s CBS structural reinforcement technology (L&L CBS) improves vehicle body structure performance. Our technology enables weight to be reduced, while maintaining or improving vehicle durability, stiffness, and crash worthiness.

L&L’s CBS structural reinforcement technology improves vehicle body structure performance. Our technology enables weight to be reduced, while maintaining or improving vehicle durability, stiffness, and crash worthiness.

L&L Reinforce technologies are used to enhance the performance of a vehicle’s body structure – weight is reduced while durability, stiffness, impact resistance and safety of the vehicle are maintained or improved.

L&L Products unique expertise in formulating high performance expandable structural adhesives provides customers with novel systems that provide optimum reinforcement exactly where it is needed in the vehicle structure, but without the risk of contamination to a customer’s anti-corrosion or paint line processes as can be the case with paste or liquid adhesives.

L&L has a detailed understanding of the design and engineering requirements of current and forthcoming CV crash safety and acoustic regulations. Using the latest material modeling and computer aided / finite element analysis software, we have significant expertise in helping customers to optimize vehicle design using L&L Reinforce systems to demonstrate improved safety and lower structure borne noise while also demonstrating reductions in overall vehicle weight.

L&L structural reinforcement technologies are available in several forms to suit a customer’s vehicle assembly and design criteria, including:

  • Dry to touch structural adhesive pre-applied to injection molded carriers
  • Dry to touch structural adhesive pre-applied to stamped metal carriers.
  • Dry to touch structural adhesive pre-applied to thermoset SMC carriers.

Composite Panel Stiffener

L&L Products Composite Panel Stiffener is an epoxy-based, high expanding structural adhesive contained within a fiberglass reinforcement. It is designed to provide improved local reinforcement and NVH and specifically to deal with excessive panel vibration and noise issues.

As a result of detailed analysis, our engineers are able to determine the ideal size and positioning of the Composite Panel Stiffener in order to provide our customers with optimal pricing and performance.

While in its green state, the panel stiffener offers excellent substrate adhesion and pliability, which allows for it to adhere around corners. Once heat is applied, the material will expand and cure allowing for a high performance stiffening patch. The high performance is due to the increased moment of inertia.

Typical application areas include door panels, roof panels, hood, fender (front & rear), lift gate and tailgate panels and floor panels.

Key Product Attributes

  • High performance stiffening due to increased moment of inertia
  • Superior adhesion to a wide range of substrates in green state
  • Enables thinner gauge panels to be used thereby saving weight
  • Ability to hold around corners
  • A price competitive solution
