This project aims at taking the first critical steps to innovatively introduce an exceptionally cost-effective composite product, WEAV3D composite lattice, to the construction industry. WEAV3D lattice is composed of fiber reinforced thermoplastic tapes, which have been woven and bonded into a lattice structure using an innovative lattice forming process. The proposed research will experimentally examine the bond characteristics of WEAV3D composite lattice embedded in concrete samples. Innovative changes to the manufacturing process to reach acceptable bond characteristics will be examined. The research will result in a novel WEAV3D product, which is suitable for the construction industry. The use of WEAV3D lattice in the construction industry will eliminate the durability problem associated with corrosion of steel reinforcing bars, which is a major economic problem for Canadian structures. Their lightweight, as compared to steel bars, will also reduce the construction time, and eliminate construction risks associated with handling of steel reinforcing bars. WEAV3D lattice will also help addressing climate change challenges by reducing the reliance on steel reinforcing bars, which impact the environment due to the damaging air emissions, wastewater contaminants, and hazardous wastes released during their manufacturing process.

该项目旨在迈出关键的第一步，创新性地将一种极具成本效益的复合产品--WEAV3D复合格栅引入建筑业。WEAV3D晶格是由纤维增强热塑性胶带组成，这些胶带使用创新的晶格形成工艺编织并粘合成晶格结构。这项研究将通过实验研究WEAV3D复合晶格嵌入混凝土试件中的粘结特性。将研究制造工艺的创新变化，以达到可接受的粘结特性。这项研究将产生一种适用于建筑行业的新型WEAV3D产品。WEAV3D格栅在建筑行业的使用将消除与钢筋锈蚀相关的耐久性问题，这是加拿大结构的一个主要经济问题。与钢筋相比，它们的重量轻，还将缩短施工时间，并消除与处理钢筋有关的施工风险。WEAV3D格栅还将通过减少对钢筋的依赖来帮助应对气候变化挑战，钢筋在制造过程中释放出破坏性的空气排放、废水污染物和危险废物，从而影响环境。
