US-Egypt Cooperative Research: Preparation and Evaluation of New Environmentally Friendly "Lignocellulosic Composites" from Waste Agricultural Products.

该奖项旨在支持宾夕法尼亚州费城德雷塞尔大学材料工程系Riad Gobran博士和埃及开罗国家研究中心纤维素和造纸部Altaf H. Basta博士的合作项目。他们计划研究利用现成的废弃农产品，如甘蔗渣、稻草和棉花秸秆作为非木材木质纤维素来源。这些将与现成的无机化合物结合使用，形成新的环保复合材料。机械、电气、生物和阻燃性能将通过改变无机化合物的种类和用量来检验和优化。将对拟议系统的经济进行研究，并将使用这些系统与传统系统的制造成本进行比较。范围：美国PI和埃及合作者在与该项目直接相关的领域有很强的研究记录和经验，即纤维素、木质素和木质纤维素材料的化学和技术及其在造纸业、复合木材以及纤维素衍生物中的应用。这两位调查员互为补充。Basta博士将对木质纤维素原料进行预处理，并制备用于替代传统树脂的新添加剂。Gobran博士将为复合材料的评估进行补充实验工作，特别是在各种条件下的韧性测量和抗冲击性。他将使用电子扫描显微镜对复合材料的形貌进行研究。双方将交换样品以测试结果的可重复性，并将参与数据和结论的分析。该提案符合INT在共同感兴趣的领域支持合作研究的目标。该项目得到了美国-埃及联合基金项目的支持，该项目向两国的科学家和工程师提供赠款，以开展这些合作活动。

0001600GobranDescription: This award is to support a collaborative project by Dr. Riad Gobran, Materials Engineering Department, Drexel University, Philadelphia, Pennsylvania, and Dr. Altaf H. Basta, Cellulose and Paper Department, the National Research Center, Cairo, Egypt. They plan to study the use of readily available waste agricultural products such as bagasse, rice straw and cotton stalks as non-wood lignocellulosic sources. These would be used in combination with readily available inorganic compounds to form new and environmentally friendly composites. The mechanical, electrical, biological and flame retardant properties will be examined and optimized by varying the type and amount of inorganic compounds used. Studies will be made of the economics of the proposed systems and comparison will be made between the cost of manufacturing using these systems against conventional systems.Scope: The US PI and the Egyptian collaborator have strong records of research and experience in areas directly related to this project, namely the chemistry and technology of cellulose, lignin, and lignocellulosic materials and their applications in paper industries, composite wood, as well as in cellulose derivatives. The two investigators complement each other. Dr. Basta will carry out pretreatment of lignocellulosic raw materials and preparation of new additives to be used as replacement of conventional resins. Dr. Gobran will carry out complimentary experimental work for the evaluation of composites, especially toughness measurements and impact resistance under various conditions. He will conduct studies of the morphology of the composites using electron-scanning microscopy. The two will exchange samples for testing of repeatability of results, and will participate in the analysis of data and conclusions. This proposal meets the INT objective of supporting collaborative research in areas of mutual interest. This project is being supported under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to carry out these cooperative activities.
