This research will focus on out-of-autoclave processing as a sustainable means of composite manufacturing. The large-scale introduction of composite materials into the aerospace industry will result in lighter planes with greater fuel efficiency. By moving composite manufacturing out of the autoclave, energy consumption during processing will be reduced and production rates will increase. Our proposal will highlight the sustainable aspects of out-of-autoclave composite manufacturing, specifically with regard to vacuum bag only (VBO) prepregs. For our purposes, "sustainability" will refer to preservation and expansion of access to affordable energy, and minimization of environmental impact.The environmental benefits to replacing metal structures with composite materials are clear. Composite parts are light-weight, providing greater fuel efficiency, and also display higher fatigue and corrosion resistance. The composite manufacturing process, however, contains inefficiencies. While moving composite processing out of the autoclave will reduce energy consumption, there are still environmental concerns associated with thermoset composite manufacturing. Waste management and energy savings are of high priority. We will address these issues through three main subject areas; waste reduction, defect control, and manufacturing efficiency.

本研究将集中于非高压灭菌处理作为复合材料制造的可持续手段。复合材料在航空航天工业中的大规模应用将使飞机更轻，燃油效率更高。通过将复合材料制造移出高压灭菌器，加工过程中的能耗将降低，生产率将提高。我们的提案将强调高压灭菌器外复合材料制造的可持续方面，特别是关于真空袋（VBO）预浸料。就我们的目的而言，“可持续性”将指的是保存和扩大获得负担得起的能源的途径，以及尽量减少对环境的影响。用复合材料代替金属结构的环境效益是显而易见的。复合材料部件重量轻，提供更高的燃油效率，也显示出更高的抗疲劳和耐腐蚀性。然而，复合材料制造过程效率低下。虽然将复合材料加工移出高压釜将降低能耗，但热固性复合材料制造仍然存在环境问题。废物管理和节约能源是重中之重。我们将通过三个主要主题领域来解决这些问题；减少浪费，控制缺陷，提高生产效率。
