The reduction of weight in transport vehicles results in higher payload, better fuel efficiency, or allows the integration of more comfort.Engineers are integrating components made of non-traditional lightweight materials such as aluminium, magnesium, and fiber reinforced plastics and composite materials to achieve a lower weight. Sika provides solutions to join dissimilar materials and expertise to cope with thermal expansion and integration challenges. We have a wide range of adhesive solutions for the effective assembly of such lightweight components in the body shop or the assembly line.
Sika’s global expertise, combined with the local technical service provides commercial vehicle manufacturers optimal solutions for individual weight saving and optimisation challenges.
"Sika’s broad set of technologies and competent technical support provide innovative and efficient solutions for lighter vehicles that have lower fuel consumption, higher payload, or increased comfort."
Sika Adhesive Technologies for Lightweight Vehicles
Sika has a unique portfolio of technologies. These were developed by taking our customer's unique challenges in mind. Our smart adhesive and coating solutions have proven their value in countless cases, globally.
High Stiffness and Elasticity SikaForce® Powerflex
Structurally joining large panels of different materials, like lightweight composites with aluminium, creates thermal expansion challenges. Most structural polyurethane or MMA adhesives become brittle in the cold and lose their strength in the warm. SikaForce® Powerflex is a unique adhesive technology that stays flexible and retains its strength regardless of service temperature.
Stiffer Body Structures by Using the full Strength of High Strength Steels
Mechanical fixtures such as screws and bolts add substantial weight to vehicles. Using them also creates stress peaks that may result in reduced longevity of the connection or the need for additional stiffening. SikaPower® SmartCore epoxy adhesives provide your engineers with additional tools to reach strength and stiffness requirements. They also allow the integration of ultra-high-strength steel and may even reduce postwork like straightening the parts or need for surface polishing.
Reinforcing Structures with Carbon Fiber Sheets and Components
SikaPower® SmartCore adhesives allow the stiffening of body structures by combining carbon fiber (CFRP) sheets with the steel structure. CFRP reinforced structures allow a significant weight reduction. With SikaReinforcer® Sika offers reinforced components and inserts for vehicles with large production volumes.
SikaDamp® Ultralite Sound Deadening Solutions
SikaDamp® Ultralite is a constrained layer material which provides highly effective sound damping. Up to 80% weight reduction compared with similar products. Targeted damping is a highly effective way to eliminate the noise associated with vibration in body panels.
