WORKSHOP: Composite Sheet Forming; September 12, 2001, Boston, Massachusetts

本次复合材料板材成形研讨会的目的是解决与提高复合材料板材成形工艺在制造业中的可行性有关的关键问题。为实现这一目标，讲习班将为实验者、建模专家、统计学家、材料供应商和最终用户提供一个论坛，目的是制定一个可行和有代表性的基准并组织执行。该基准将用于标准化这类新材料的材料测试程序，并检查当前模拟中的最先进技术。预计研讨会将具有重要的国际代表性，并将促进美国的这类研究，不幸的是，美国的研究不如我们在欧洲和亚洲的同行那么活跃。复合材料板材成形已显示出巨大的潜力，可以以极低的制造成本提供高强度和低重量的产品。这一成本降低主要归因于显著缩短的周期时间和部件整合。在过去的几年里，一个由学术和行业研究人员组成的国际小组在制造原型部件的同时，对材料行为和成型过程进行了研究。这项工作的结果是大量的实验和建模数据。然而，由于这一领域的研究仍然相对较新，与较长的板材成形历史相比，这些结果中的许多导致了更多的问题而不是答案，这在最近的技术会议上得到了很好的回应。复合材料板材成形的研究工作正处于一个关键时刻，基准将导致我们在理解现有实验和建模方法的优点和局限性方面取得重大进展。

The aim of this Workshop on Composite Sheet Forming is to address key issues related to improving the viability of the composite sheet forming process in manufacturing. To accomplish this, the workshop will provide a forum for experimentalists, modeling specialists, statisticians, material suppliers and end users with the goal of formulating a feasible and representative benchmark and organizing for its execution. The benchmark will be used to standardize materials testing procedures for this new class of materials and to examine the current state-of-the-art in simulation. It is expected that the workshop will have significant international representation and will stimulate this kind of research in the U.S., which is unfortunately less active than our counterparts in Europe and Asia. Composite sheet forming has demonstrated great potential as a valuable alternative to provide high-strength and low-weight products at a much-reduced manufacturing cost. This cost reduction is due primarily to significantly shorter cycle times and parts consolidation. Over the past several years, an international group of academic and industry researchers has conducted studies of the material behavior and the forming process, in conjunction with fabrication of prototype parts. The outcome of this work is a substantial body of experimental and modeling data. However, as the research in this area is still relatively new, as compared to the longer history of sheet metal forming, much of these results have lead to more questions than answers, which was well echoed at recent technical conferences. The state of the research efforts in composite sheet forming are at a critical point where benchmarking will lead to major advances in our understanding of the strengths and limitations of existing experimental and modeling approaches.
