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上销售的汽车的燃油经济性。到2015年，新车的平均二氧化碳排放量为每公里130克（g/km），到2021年为每公里95克。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。轻型车辆使燃油效率高的发动机获得类似的性能。CFRP比铝轻30%，相当于同等体积钢重量的20-25%。由于模具和制造成本昂贵，CFRP仅适用于小众，小批量运动和高规格车辆。目前的CFRP面板制造涉及使用六轴机器人系统应用液体粘合剂，然后在夹具中夹紧，并使用长达7小时的加热固化过程。CFRP面板间隙受到严格控制，以最大限度地提高粘合性能。只有在基础设施成本非常高、碳足迹很大的情况下，成本才会令人望而却步。特克曼特种材料公司（TSM）是英国一家为一级和二级汽车供应商生产胶带的老牌公司。胶带可以潜在地克服CFRP制造中使用的液体粘合剂的问题。高初始附着力和快速固化时间提供了加工速度，以扩大CFRP制造到主流车辆。然而，目前胶带中使用的压敏粘合剂（PSA）没有足够的附着力或整体强度来形成CFRP板之间的结构粘合。与Adhesive Applications International (AAI) CMC Cevenini （CN）和ExpertTooling （ExT）合作，Tecman将在一个成功的12个月项目中率先推出CFRP双作用胶带（CFRPb - DAAT®）的概念，用于大批量生产。将初始压力激活胶带的优点与二次热激活液体粘合剂的性能相结合，将为CF在中大型汽车制造中的主流使用铺平道路，以降低排放

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
