The theoretical possibilities of improving the adhesion between a polypropylene matrix and cellulose natural fibres are well known. However, less is known of how the way of adding MAH‐PP products into the composite impacts the adhesion. By comparing mat processes and granule processes this influence on the adhesive effect can be seen. A new process manufacturing natural fibre reinforced granules ( developed in TITK ) was used for these comparisons. It could be shown that the adhesive obviously influences the critical fibre length.

“…For example, it has been known for over a decade that composites reinforced with flax fibers showed stiffness comparable or even better than that of commercial composites reinforced with glass mat and thermoset sheet molding compound. [32][33][34] However, due to the composite-like structure of lignocellulosic fibers, the opposite of single filament synthetic fibers, 35 the strength of composites with flax fibers was low compared to the strength of composites reinforced with glass fibers. 33 Natural fibers can take different forms that depend on the degree of fiber isolation, variable surface characteristics, and fiber processing and treatment conditions.…”

Natural cellulose-based fibers offer low cost, low density composite reinforcement with good strength and stiffness. Because of their annual renewability and biodegradability, natural fibers have materialized as environmentally-friendly alternatives to synthetic fibers in the last two decades. They are replacing synthetic materials in some traditional composites in industrial manufacturing sectors such as automotive, construction, furniture, and other consumer goods. In this work, the use of lignocellulosic fibers in green materials engineering, particularly their application as polymeric composite reinforcement and surface treatment via ionizing radiation are reviewed. Because these cellulose-based materials are intrinsically hydrophilic, they require surface modification to improve their affinity for hydrophobic polymeric matrices, which enhances the strength, durability, and service lifetime of the resulting lignocellulosic fiber-polymer composites. In spite of a long history of using chemical methods in the modification of material surfaces, including the surface of lignocellulosic fibers, recent research leans instead towards application of ionizing radiation. Ionizing radiation methods are considered superior to chemical methods, as they are viewed as clean, energy saving, and environmentally friendly. Recent applications of controlled ionizing radiation doses in the formulation of natural fiber -reinforced polymeric composites resulted in products with enhanced fiberpolymer interfacial bonding without affecting the inner structure of lignocellulosic fibers. These applications are critically reviewed in this contribution.

Linum Usitatissimum L. is mostly known as flax usually cultivated to consume the fibre demand for apparel and edible oil production. However, recent development and research work have made the diversification of flax polymers to be a part of a growing trend to fabricate biodegradable composites. Although, flax is traditionally grown for its natural plant oil seeds, but it also carries the prospects to be applied in bio-composites either in form of reinforcements or as polymer matrix. Since flax is a biodegradable polymer, the use of flax in composite reinforcement can introduce the concept of green composite that may contribute in lowering the carbon footprint around the globe. The inherent composite characteristics of flax fiber provide outstanding mechanical properties. Further, the technology for producing bio-based resin from flax oil for industrial application has added additional value offering significant opportunities for new and improved materials from renewable resources. This review intends to discuss few of the key points that summarize the promising features of flax in fabricating biodegradable composites. VARTM is one of the significant manufacturing methods of flax reinforced composites using non-woven flax mat where flax mat is usually formed by web formation method through air or wet lying technique. Flax fibre properties, effect of manufacturing parameters like needle punch density, mat areal density and consolidation pressure while manufacturing composites play an important role on the strength and modulus of flax reinforced composites.
