... In recent years, there has been a focus on alternative matrix materials that can be recycled and reused easily after the end of their life. [194] Commercial companies like Connora Technologies and Adesso Advanced Materials Co. Ltd. have developed acid-degradable and amine-based hardeners which allow thermoset epoxy to be broken apart upon the addition of a suitable acid. [195][196][197] A similar strategy has been developed using anhydride hardener that can easily be broken down by an acidic solution in the presence of a zinc chloride catalyst. ...

Sustainable fiber reinforced polymer (FRP) composites from renewable and biodegradable fibrous materials and polymer matrices are of great interest, as they can potentially reduce environmental impacts. However, the overall properties of such composites are still far from the high‐performance conventional glass or carbon FRP composites. Therefore, a balance between composite performance and biodegradability is required with approaches to what one might call an eco‐friendly composite. This review provides an overview of sustainable FRP composites, their manufacturing techniques, and sustainability in general at materials, manufacturing, and end‐of‐life levels. Sustainable plant‐based natural fibers and polymer matrices are also summarized, followed by an overview of their modification techniques to obtain high‐performance, multifunctional, and sustainable FRP composites. Current state‐of‐the‐art mechanical and functional properties of such composites are then surveyed, and an overview of their potential applications in various industries, including automobile, aerospace, construction, medical, sports, and electronics is provided. Finally, future market trends, current challenges, and the future perspective on sustainable natural FRP composites are discussed.
... Poly-lactic acid (PLA) is a biodegradable polymer which is produced on a large scale from the lactic acid monomer from the fermentation of mainly renewable agricultural raw materials that has a special interest as a matrix in natural fibre composites for many reasons as compared to other biodegradable polymers (Oksman, Skrifvars & Selin [11]; Porras & Maranon [14]; Qin et al. [15]). Firstly, PLA has good mechanical properties almost similar to polystyrene (PS) and polyethylene terephthalate (PET) where its flexural modulus is better than PS and resistance to fatty foods and dairy products equivalent to PET (Lunt [7]; Porras & Maranon [14]).Next, PLA can be fabricated into moulded parts, films, fibres and many more as it can be melt-processed with standard processing equipment at temperatures below those at which natural fibres start to degrade (Porras & Maranon [14]; Qin et al. [15]; Srebrenkoska, Gaceva & Dimeski [17]). Lastly, the most commercially attractive feature of PLA is that it can be biodegraded through hydrolysis to lactic acid as compared to synthetic polymers (Oksman, Skrifvars & Selin [11]; Porras & Maranon [14]). ...

This work reports the development of a composite material from both renewable resources and biodegradable materials: modification of poly-lactic acid (PLA) with rice straw fibre loading. PLA-RS fibres composites were prepared with different fibre loadings (5 – 15 vol%) with different layout sequence; sequential layering and batch-mixed using hot press. The flexural strength of the PLA-RS fibre composites prepared using the both sequential layering and batch-mixed reduced with increasing fibre loading but for batch-mixed, the flexural strength increased at 10 vol% fibre loading and reduced again thereafter. In this case, RS fibres were not able act as reinforcement for PLA.

The present work reports a novel process for developing advanced chemically designed materials by utilizing both bamboo stem and fly ash's inherent chemical and complementary properties. The process involves forming unique heterogeneous tailored precursor material using treated bamboo stem and Class F-fly ash to develop advanced chemically designed material in a Panel form. In the process, the bamboo stem plays a dual role by helping in the in-situ formation of chemicals like sodium silicates; sodium lignates etc. which are essential for the formation of geo polymeric moieties during the reaction processing in the developed product. The other is the so formed cellulosic derived fibers are used as natural reinforcement fibres.
