DuPontTM Kevlar® is a para-aramid fiber invented by DuPont to provide high strength, lightweight and heatstability properties in textile and composite applications. For many years, Kevlar® was solely used in militaryapplications, primarily due to its superior mechanical properties as well as its limited availability. However, therecent increased production of Kevlar® has made it widely available for civil applications. From a materialstandpoint, Kevlar® is characterized by superior mechanical properties, good fire resistance and very lowdensity. These characteristics make Kevlar® extremely attractive to numerous industries such as automotive,rail transportation or aerospace. However, in order to use Kevlar® in civil industry, an adequate technology forhigh-volume fabrication of Kevlar® reinforced composites is yet to be identified. Once this manufacturing pathhas been found, the mechanical properties of the resulting composite will have to be evaluated in order to bettertarget the needs of the future civil customers. To address this, DuPont has expressed - through the currentproposal - interest in partnering up with researchers from Western University and Fraunhofer Project Center inan attempt to test the feasibility of the new HPRTM technology for Kevlar-reinforced composite fabrication. Ifsuccessful, this fabrication avenue could open up a new spectrum of collaboration activities between theinvolved organizations to be then followed by beneficial downstream effects for the entire Canadianmanufacturing sector.

DuPontTM Kevlar®是杜邦公司发明的一种对位芳纶纤维，可在纺织品和复合材料应用中提供高强度、轻质和热稳定性。多年来，Kevlar®仅用于军事应用，主要是由于其上级机械性能以及其有限的可用性。然而，最近Kevlar®产量的增加使其广泛用于民用应用。从材料的角度来看，Kevlar®具有上级机械性能、良好的耐火性和极低的密度。这些特性使Kevlar®对汽车、铁路运输或航空航天等众多行业极具吸引力。然而，为了在民用工业中使用Kevlar®，尚未确定大批量制造Kevlar®增强复合材料的适当技术。一旦找到了这种制造途径，就必须评估所得复合材料的机械性能，以便更好地满足未来民用客户的需求。为了解决这个问题，杜邦公司通过目前的提案表示有兴趣与西方大学和弗劳恩霍夫项目中心的研究人员合作，尝试测试新的HPRTM技术用于芳纶增强复合材料制造的可行性。如果成功的话，这种制造途径可以在相关组织之间开辟一个新的合作活动范围，然后对整个制造业产生有益的下游影响。
