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

复合材料板成形研讨会的目的是解决与提高复合材料板成形工艺在制造业中的可行性有关的关键问题。 为了实现这一目标，研讨会将为实验人员、建模专家、统计人员、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的、有代表性的基准，并组织实施。 该基准将用于标准化这类新材料的材料测试程序，并检查当前最先进的模拟。 预计该研讨会将具有重要的国际代表性，并将促进美国的此类研究，不幸的是，它不如欧洲和亚洲的同行活跃。复合材料板材成形已显示出巨大的潜力，作为一种有价值的替代方案，以大大降低的制造成本提供高强度和低重量的产品。 这种成本降低主要是由于大大缩短了周期时间和零件整合。 在过去的几年里，一个国际学术和工业研究小组对材料行为和成型过程进行了研究，并结合原型零件的制造。 这项工作的成果是大量的实验和建模数据。 然而，由于这一领域的研究相对较新，与金属板材成形的较长历史相比，这些结果中的大部分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。 在复合材料板材成形的研究工作的状态是在一个关键点，基准将导致我们的理解现有的实验和建模方法的优势和局限性的重大进展。

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.
