Attention has been growing globally on the need for new materials that are sustainable. Interest is forcing industry to change their approach to recyclability, bio-degradability and to replace current, oil-based materials with renewable ones. Some petroleum plastic based products are recyclable, but large portions still end up in our landfills. The research will evaluate non-food related agricultural plant-based fibre materials such as hemp, kenaf and jute mixed with an epoxy resin that has been substituted with a large percentage of bio-based resins such as soybean, pine or castor oils. The performance (e.g. tensile, compression, flexural bend strength, Charpy impact toughness, cyclic fatigue and high and low temperature durability) of small and larger scale composites will be evaluated to determine their suitability as civil engineering construction materials. The fundamental mechanisms of mechanical and chemical material interactions will be investigated. New market applications could include hollow tubes, sandwich panels for rapid construction, panelling, tiles, building siding and stay-in-place concrete forms.**The training of highly qualified personnel will allow 4 undergraduate summer students, upper year, 4 M.Sc. (2 full and 2 co-supervisions) and 2 Ph.D. students to develop the processes involved in the materials selection, manufacturing procedure, experimental mechanical testing, theoretical analysis and to recommend an end use for this novel material. Natural fibres with bio-based polymer resins have been successfully implemented in certain areas of the automotive and packaging industries but have not been developed in the construction industry. This program promotes farming; it expands Canada's agricultural diversity and industries. Business spin-offs from this program range from bio-fibre growth to processing of fibres into fabrics. Canada has large quantities of forestry wood scraps and agricultural biomass as such bio-resin production plants could be created. This research program develops the science and engineering needed to extend the planet's natural resources for future generations.********

全球对可持续新材料的需求越来越关注。人们的兴趣迫使工业界改变其回收利用和生物降解的方法，并用可再生材料取代目前的石油基材料。一些石油塑料产品是可回收的，但大部分仍然在我们的垃圾填埋场结束。该研究将评估与非食品相关的农业植物纤维材料，如大麻，红麻和黄麻与环氧树脂的混合物，该环氧树脂已被大豆，松树或蓖麻油等生物基树脂取代。将评估小型和大型复合材料的性能（例如拉伸、压缩、弯曲弯曲强度、夏比冲击韧性、循环疲劳和高低温耐久性），以确定其作为土木工程建筑材料的适用性。将研究机械和化学材料相互作用的基本机制。新的市场应用可能包括空心管、用于快速施工的夹层板、镶板、瓷砖、建筑壁板和原地混凝土模板。**高素质人才的培训将允许4个本科暑期学生，高年级，4个硕士（2个全职和2个共同监督）和2个博士。学生们将开发涉及材料选择，制造程序，实验机械测试，理论分析的过程，并推荐这种新型材料的最终用途。具有生物基聚合物树脂的天然纤维已成功应用于汽车和包装行业的某些领域，但尚未在建筑行业中开发。该计划促进农业;它扩大了加拿大的农业多样性和产业。该计划的商业附带利益包括从生物纤维增长到将纤维加工成织物。加拿大有大量的林业木材废料和农业生物质，可以建立这样的生物树脂生产工厂。该研究计划开发为子孙后代扩展地球自然资源所需的科学和工程。
