| Title | Novel Adhesives for Bonding Friction Materials to Clutch Discs (Automotive) |
| Knowhow is available for | A novel adhesive composition that allows bonding friction materials to clutch discs without use of rivets, resulting in longer-lasting, cheaper, lighter clutch discs. |
| Summary | NCL scientists have developed a novel adhesive composition that can be used to bonding (without use of rivets) friction materials to the clutch discs. A unique formulation provides the necessary bond (lap shear) strength without compromising on the required cushioning properties for clutch applications. This would lead to a radical increase in the lifetime of the clutch discs, and also make them cheaper. [Temperature stability up to 150â°C (exposure time~30–40 hrs); lap shear strength~10-15 Kg/cm2; cushioning~0.3-0.4 mm.] |
| Advantages | • Adhesively bonded clutch discs fully utilize the friction material, thus reducing loss of the expensive component, and also increasing the lifetime of the clutch disc
• It also leads to the overall reduction of the weight of the clutch disc
• The process for preparing adhesively bonded discs are comparatively easier, cheaper
