SBIR Phase II: Development of Smart Material Using Natural Fiber Reinforced Composite

该小型企业创新研究（SBIR）第二阶段项目建议开发一种基于主动-被动天然纤维复合材料（APNFC 0）的合适原型，其技术可行性已在第一阶段计划中得到证明。这种创新的复合材料概念是生物基的，因此是环保的。APNFC具有出色的振动和噪声缓解性能，可用于控制各种噪声环境中的声学噪声和结构振动。这种复合材料的独特设计将通过吸收和耗散现象的组合来减少宽频带上的噪声传输。在第二阶段建造的原型将包括一个热成型的夹层材料配置，其中聚合物基压电层（PVdF）形成在两个由可变密度天然纤维复合材料（VDNFC）组成的被动层之间。这种材料将具有带放大器和电源的嵌入式控制系统，新技术的商业应用包括：家用电器、隔音建筑门、办公家具、农业和建筑机械的操作员舱、建筑材料、汽车和飞机客舱。总的来说，这些代表了数十亿美元的零件和产品市场，目前的核心技术可以应用于这些市场。该公司有一个集中的商业化计划与战略合作伙伴的支持，在家电应用和办公室和建筑应用

This Small Business Innovation Research (SBIR) Phase II project proposes to develop a suitable prototype based on the Active-Passive Natural Fiber Composite (APNFC0), the technical feasibility of which was demonstrated in the Phase I program. This innovative composite material concept is bio-based and hence environmentally friendly. The APNFC has excellent vibration and noise mitigation properties and can be used to control acoustic noise and structural vibrations in a wide variety of noisy environments. The unique design of this composite material will reduce noise transmission over a broad band of frequencies through a combination of absorption and dissipation phenomena. The prototype to be built during Phase II will consist of a thermoformed sandwiched material configuration where a polymer-based piezoelectric layer (PVdF) is formed between two passive layers composed of variable density natural fiber composite (VDNFC). This material will have an embedded control system with amplifiers and power supplies.The commercial applications of the new technology include: home appliances, soundproof architectural doors, office furniture, operator cabins for agricultural and construction machinery, building materials, automobiles, and aircraft cabins. Collectively, these represent a multi-billion dollar market for parts and products to which the present core technology can be applied. The company has a focus commercialization plan with strategic partner support in the appliance application and the office and construction applications
