“…In the 14th century, the spindle to manufacture wool and cotton fibers emerged. The evolution in this field did not stagnate and the production of fibers continue evolving until the 19th century, dramatically increasing the use of natural fibers in the 1940s [ 11 , 134 ]. Years later, in the middle of the 20th century, the production of synthetic fibers began [ 11 ].…”

In the last decades, much research has been done to fasten wound healing and target-direct drug delivery. Hydrogel-based scaffolds have been a recurrent solution in both cases, with some reaching already the market, even though their mechanical stability remains a challenge. To overcome this limitation, reinforcement of hydrogels with fibers has been explored. The structural resemblance of fiber–hydrogel composites to natural tissues has been a driving force for the optimization and exploration of these systems in biomedicine. Indeed, the combination of hydrogel-forming techniques and fiber spinning approaches has been crucial in the development of scaffolding systems with improved mechanical strength and medicinal properties. In this review, a comprehensive overview of the recently developed fiber–hydrogel composite strategies for wound healing and drug delivery is provided. The methodologies employed in fiber and hydrogel formation are also highlighted, together with the most compatible polymer combinations, as well as drug incorporation approaches creating stimuli-sensitive and triggered drug release towards an enhanced host response.

“…26 Applications of green composites are limited due to many durability-related parameters, including ambient moisture content, biodegradation, UV exposure, and weathering effects. [26][27][28][29][30] A weathering study conducted on green composites by Miller et al 26 has signified the importance of geographic location and weather conditions on use phase material degradation, with warm, moist climates inducing faster degradation rates and more severe ecological effects.…”

“…The timedependent degradation of composites poses challenges to engineers when choosing the correct material for longterm applications, as it is often accompanied by significant reductions in mechanical properties which can lead to material failure. [26][27][28][29][30] One method of integrating the effects of durability on environmental impact is by using an LCA. 26,41,42 Multiple environmental impact categories can be utilized to quantify the ecological effects of composite durability.…”

“…Moisture absorption is particularly important in the context of composites made of natural fibers, as these fibers tend to be hydrophilic and more readily sorb water than synthetic fibers. [26][27][28]30 The presence of hemicellulose, a structural component in natural fibers, is the main source of this hydrophilic tendency. 30 Moisture uptake inside the composite also causes intermolecular hydrogen bonding between the water and fibers, which reduces interfacial fiber-matrix adhesion.…”

“…43 The net effect of moisture absorption within natural fibers is considerably lower mechanical properties and compromised long-term durability. [26][27][28][29][30] Water absorption tests conducted by Dhakal et al 44 tested the change in mechanical properties of composites composed of hemp fibers and an unsaturated polyester matrix. Multiple composite samples of different fiber volume fractions were dried in an oven before being immersed in deionized water for 888 h. Tensile and flexure tests were conducted before and after immersion to measure mechanical property deterioration.…”

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.
