“…Although extensive research has been conducted regarding the durability, life cycle analyses, and mechanical properties of green composites, work from these categories as they relate to green braided composites are sparse. Unlusoy and Melenka 94 demonstrated the effects of area moment of inertia, braiding angle, and void content on the flexural properties of cellulose-based braided composites. Rajesh and Pitchaimani 95 discovered that braided architectures of jute-based composites have enhanced mechanical properties when compared to the conventional woven fabric architecture.…”

Increasing concerns regarding human-driven effects on the biosphere have led to the development and adoption of environmentally friendly “green” composites. Unlike conventional synthetic composites, green composites are made of natural materials in either the matrix or the fiber reinforcement (or both). They are claimed to have lower negative environmental effects due to their sustainability and easier recyclability. To assess the environmental impacts associated with any product, a life cycle assessment (LCA) is needed. This literature review summarizes the individual steps undertaken in an LCA study and discusses their relevance within the field of green composites. Similarly, an outline of life cycle costing (LCC), a type of study which determines the economic implications of a product, is incorporated. Since some phases of a product’s life cycle can have significant environmental effects, parameters affecting the time-dependant degradation of green composites and their significance in LCA studies were also explored. Finally, criteria for choosing natural fibers and biopolymers for green composites in engineering applications were considered, and case studies of hemp and flax as candidates for fiber cultivation in Alberta, Canada are provided throughout.

“…In order to measure and compare the surface strains during three-point flexure, a three-dimensional digital image correlation (DIC) system was used during the flexure test for one repeat of each braid angle. As demonstrated in literature [34,35], DIC is useful for recording the multiaxial strains as well as out-of-plane deformations induced during flexural testing.…”

“…In order to better understand the degradation phenomena occurring in NFCs submitted to moisture environment, it is necessary to characterise the corresponding damage and deformation mechanisms. Different types of techniques can be used to characterise damage and strain in NFCs: optical and electronic microscopy (Pickering et al, 2016;Malinowski et al, 2018), acoustic emission (De Rosa et al, 2009;Assarar et al, 2011), digital image correlation Unlusoy et al, 2019), ultrasonic scanning (Lebaupin et al, 2019;Fischer et al, 2019), infra-red thermography (Boccardi et al, 2018;Zhang et al, 2018) and X-ray micro-tomography (Rasket et al, 2012;Perrier et al, 2017). Figure 4 illustrates the ability of X-ray micro-tomography to analyse damage development in NFCs.…”

Please provide a 200 word synopsis of the article, which will be used to summarise the work when presented online. This topical review covers the mechanical properties of natural fibre composites (NFCs) that allow applications in many application fields ranging from infrastructure to transportation. Climate change alerts on the importance of sustainability and NFCs offer opportunities when compared to conventional glass-fibre composites. Advantages and drawbacks of NFC versus synthetic composites are considered and discussed. Mechanical properties are assessed both statically and dynamically. The hydrophilicity and its consequences on damage and deformation mechanisms are also addressed. The key to making well-reinforced composites is by ensuring that there is a strong interface between the reinforcing phase and the matrix phase. The interfacial bonding quality is thus discussed through various testing methods and the effects of surface treatments are presented.
