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基于主动-被动天然纤维复合材料(APNFC0)的合适原型，其技术可行性在第一阶段项目中得到了论证。这种创新的复合材料概念是基于生物的，因此是环保的。APNFC具有优异的减振降噪性能，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消散现象的结合来减少在宽频带上的噪音传输。将在第二阶段建造的原型将包括热成型夹层材料配置，其中聚合物基压电层(PVDF)在由变密度天然纤维复合材料(VDNFC)组成的两个被动层之间形成。这项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、建材、汽车和飞机机舱。总体而言，这些代表着一个数十亿美元的零部件和产品市场，目前的核心技术可以应用到这些市场上。该公司有一个重点商业化计划，在家电应用以及办公和建筑应用方面提供战略合作伙伴支持

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
