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.

这一小型企业技术转移(STTR)第二阶段项目的更广泛影响是开发一种可行且可扩展的工艺，以生产用于全球低成本屋顶的竹基纤维复合材料。该项目开发了一种新的外墙级天然纤维复合建筑产品的生产工艺，通过公私合作伙伴关系从高度可再生的资源竹子中提取出来。由此产生的屋顶产品将通过被动降温和降低室内温度来帮助用户免受极端高温的影响。此外，该解决方案还可用于利用高度可再生的天然纤维废料创建增值节能建筑产品。这项创新具有巨大的潜力，可以在世界许多地区取代有害和危险的材料，包括石棉，将捕获的碳存储到长生命周期产品中，并减少供暖和制冷能源的使用。这个小型企业技术转移(STTR)第二阶段项目将：(I)改进3D面板几何结构的设计，用于制造具有更高承载能力和可施工性的商业尺寸面板；(Ii)改进竹绞线工艺，评估生物基胶粘剂系统，赋予阻燃性能，增强面板耐用性，使用新几何形状制造面板，并评估性能；以及(Iii)通过现场测试和瓦楞纸板在室内和室外节能建筑产品中的多功能性来演示和评估作为屋面材料的板材的使用。这项研究将推动天然纤维复合材料领域的发展，解决长期建筑应用中能够经受湿热气候的挑战，包括防潮、生物降解和有效的功能性粘结剂。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
