The broader impact of this Small Business Technology Transfer (STTR) Phase II project is to develop a viable and scalable process to manufacture a bamboo-based strand composite for application in low-cost roofing globally. This project develops a new production process for exterior-grade natural fiber composite building products, derived from a highly renewable resource, bamboo, through public-private partnership. The resulting roofing product will help protect users from extreme heat by passively cooling and reducing indoor temperatures. In addition, this solution can be used to create value-added energy-efficient building products from highly renewable natural fiber waste. The innovation holds immense potential to replace harmful and hazardous materials, including asbestos, in many regions of the world, store captured carbon into long-lifecycle products, and reduce heating and cooling energy use.This Small Business Technology Transfer (STTR) Phase II project will: (i) refine the design of the 3D panel geometry used to make commercial-size panels with improved load-carrying capacity and constructability; (ii) improve the bamboo-stranding process, evaluate a bio-based adhesive system, impart fire-retardance, enhance panel durability, manufacture panels using the new geometry, and evaluate performance; and (iii) demonstrate and evaluate panel use as a roofing material through field tests and the versatility of the corrugated panel in interior and exterior energy-efficient building products. This research will advance the field of natural fiber composites by addressing challenges of long-term construction applications that can withstand hot and humid climates, including moisture resistance, biodegradation, and effective binders for functionality.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这种小型企业技术转移（STTR）II期项目的更广泛影响是开发一个可行且可扩展的过程，以制造基于竹子的链链复合材料，以在全球范围内在低成本屋顶上应用。 该项目为外部天然纤维复合建筑产品开发了一个新的生产过程，该产品源自公私合作伙伴，源自高度可再生资源，即竹子。 由此产生的屋顶产品将通过被动冷却和降低室内温度来帮助保护用户免受极端热量的影响。此外，该解决方案可用于从高度可再生的天然纤维废物中创建增值的节能建筑产品。在世界许多地区，创新具有替换有害和危险的材料（包括石棉）的巨大潜力（ii）改善竹施工过程，评估基于生物的粘合剂系统，赋予耐火性，增强面板耐用性，使用新几何形状制造面板并评估性能； （iii）通过现场测试以及瓦楞纸面板在内部和外部能源有效的建筑物产品中的多功能性来证明和评估面板用作屋顶材料。这项研究将通过解决可以承受炎热和潮湿气候的长期建筑应用的挑战，包括耐水性，生物降解和有效功能的有效粘合剂，来推动天然纤维复合材料的领域。该奖项反映了NSF的法定任务，并通过使用该基金会的知识分子优点和广泛的影响来评估NSF的法定任务，并被视为值得的支持。
