The Small Business Innovation Research (SBIR) Phase I project will demonstrate the use of a new carbon/epoxy prepeg formulation and tape placement process to produce a polymer matrix composite (PMC) that meets large aircraft structural compsoite specifications. Conventional carbon/epoxy prepeg and tape placement processing may produce composites with bubble and void defects. Two innovative technologies are integrated to accomplish this proposal. A carbon/epoxy prepeg tape is made by dispersing an infrared absorber into an epoxy resin and coating the resin onto carbon fiber. An infrared radiation unit is used to uniformly irradiate the prepeg tape during layup, minimizing bubbles and voids in the final composite. The proposed work will define the prepeg formulation and radiation processing conditions to form a dfect free composite, evaluate the composite properties and define the requirements for prepeg manufactuing scaleup in a Phase II program. Upon successful demomnstration of the proposed research, the participating prepeg supplier and aircraft parts manufacturer are seeking a rapid scaleup in Phase II and commercialization of the prepeg and automated tape placement process. There is an immediate industry demand for a defect free PMC manufacturing process to replacing the current, less consistent process. Availability of a defect free PMC process will drive expansion of composite use and growth in the aircraft-manufacturing segment and subsequent growth of the total US economy. The new PMC process is broadly applicable in military and commercial aircraft, ground transportation vehicles, marine boats and industrial equipment manufacturing. The proposed research includes support and training for an undergraduate student.

小型企业创新研究（SBIR）I阶段项目将证明使用新的碳/环氧树脂预元公式和磁带放置过程来生产符合大型飞机结构构成规格的聚合物基质复合材料（PMC）。 常规的碳/环氧树脂预科和胶带放置处理可能会产生带有气泡和空隙缺陷的复合材料。 整合了两种创新技术来完成该建议。通过将红外吸收剂分散到环氧树脂树脂中并将树脂涂在碳纤维上，制造碳/环氧胶带。 红外辐射单元用于在上载过程中均匀地照射预胶带，最大程度地减少最终复合材料中的气泡和空隙。 拟议的工作将定义预性公式和辐射处理条件，以形成不含DFECT的复合材料，评估复合属性并定义II期计划中预性制造规模的要求。经过拟议的研究成功的Demomnstration后，参与的预科供应商和飞机零件制造商正在寻求第二阶段的快速规模，并寻求预科和自动化磁带放置过程的商业化。直接的行业需求对无缺陷的PMC制造过程有替换当前，较不一致的过程的需求。 无缺陷的PMC过程的可用性将推动飞机制造领域的复合使用和增长的扩展以及随后的美国总经理的增长。 新的PMC工艺广泛适用于军用和商业飞机，地面运输车辆，船用船和工业设备制造。 拟议的研究包括对本科生的支持和培训。
