“…Therefore, even at the dose of 10 MGy, CF-10 can still maintain 86.53% of the initial modulus without stabilizer. This is much better than other polymeric materials, such as epoxy resin, polysulfone, polyester, etc. In general, CF-10 is a very suitable candidate material for application in radiation environment.…”

In this study, polyimide (PI)/carbon fiber (CF) aerogel was fabricated via a freeze-drying method. The introduction of CF endows PI aerogels with good dimensional stability in the thermal imidization process. The resulting aerogel possesses excellent mechanical property (as high as 58.45 MPa) and good hydrophobic property (contact angle above 120°). The PI/CF aerogel also has very good radiation resistance, with a compressive modulus of 50.45 MPa even after 10 MGy irradiation, which is 86.53% of the initial modulus. These characteristics make the PI/CF aerogel very suitable for applications in radiation environment. Subsequently, a carbon aerogel with high temperature resistance and good mechanical properties was obtained by carbonization of the PI/CF aerogel. Its comprehensive property is comparable to traditional porous carbon-bonded carbon fiber composites.

“…Samples with 10%, 20%, and 30% fiber weight fractions experienced drops in their tensile strength of 58%, 37%, and 23%, respectively, suggesting that increasing fiber weight fractions within the composite correlates to an increase in the retention of tensile properties after UV exposure due to the photodegradation effects endured by the polymer. Research conducted by Da Silva et al 47 tested hybrid composites made of carua-aramid reinforcement combined with unsaturated polyester resin under UVR and gamma radiation. The samples irradiated with UV light were placed inside an aging chamber for exposure times of 300 and 600 h. Three-point bending tests was performed on the samples after irradiation.…”

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.
