Tecman Speciality Materials (TSM) , Carbon Fibre Reinforced Plastic Dual Action Adhesive Tape (CFRPb-DAAT) proof of concept

2014年，汽车排放的二氧化碳占欧盟总排放量的12%。欧盟立法旨在提高在欧洲市场销售的汽车的燃油经济性。到2015年，车队的平均新车排放量为每公里130克二氧化碳，到2021年为每公里95克二氧化碳。汽车上的碳纤维增强塑料(CFRP)为实现这些目标提供了一种方法。轻型车使省油的发动机能够获得类似的性能。CFRP可以比铝轻30%--相当于类似体积钢材重量的20%-25%。胶带有可能克服碳纤维复合材料生产中使用的液体胶粘剂的问题。较高的初始粘合力和快速固化时间提供了处理速度，以便将CFRP生产扩大到主流车辆。

Cars were responsible for 12% of total EU emissions of Carbon Dioxide (CO2) in 2014. EUlegislation aims to improve fuel economy of cars sold on the European market. Fleet averagesfor new cars is 130g CO2 per km (g/km) by 2015 –and 95g/km by 2021. Carbon FibreReinforced Plastic (CFRP) on motor vehicles offers a method to achieve these targets. Lightervehicles enable fuel efficient engines to obtain similar performance. CFRP can be 30% lighterthan aluminium - 20-25% of the weight of steel of similar volume. Due to tooling andmanufacturing costs CFRP is expensive, suitable only for niche, low volume sports and highspecification vehicles.Current CFRP panel manufacture involves liquid adhesives applied using 6 axis roboticsystems followed by clamping in jig fixtures and curing process using heat up to 7 hours.CFRP panel gaps are closely controlled to maximise adhesive performance. Costs areprohibitive and scalable only with very high infrastructure costs and large carbon footprint.Tecman Speciality Materials (TSM) is an established UK converter of adhesive tapes for Tier1 and 2 automotive suppliers. Adhesive tapes can potentially overcome issues with liquidadhesives used in CFRP manufacture. High initial adhesion and rapid cure time provideprocessing speed to scale up CFRP manufacture to mainstream vehicles. However pressuresensitive adhesives (PSA’s) used in current adhesive tapes do not have sufficient adhesion orintegral strength to form a structural bond between CFRP panels.Working with Adhesive Applications International (AAI) CMC Cevenini (CN) & ExpertTooling (ExT), Tecman will pioneer the concept of CFRP Dual Action Adhesive Tape(CFRPb - DAAT®) for high volume production over a successful 12 month project.Combining benefits of initial pressure activated adhesive tape with performance of asecondary heat activated liquid adhesive this will pave the way for mainstream use of CF inmedium - large volume vehicle manufacture to lower emissions
