Classifications of composite nonwovens
-
Complex nonwoven reinforced composites (NRC) The composites are formed by needle-punching, thermo-bonding/stitching, hydroentangling, and latex-bonding through bonding with nonwoven fabric or two and more webs.
-
Laminated NRC Nonwoven fabrics are combined with two or additional layers to form a stable single layered laminated composite by using adhesive or thermal treatment. The laminated NRCs are stronger than complex NRCs in terms of internal bonding. However, if the bonding is not adequate for technical reasons, separation of the sheets could be challenging.
-
Blended NRC The fibers are of different origins but have similar characteristics or dissimilar characteristics but different origins or with a combination of both are mixed together to produce technology-blended NRCs.
-
Technology combined NRC Different technologies of web-bonding or web forming or a combination of both are used to manufacture technology combined NRCs.
-
Coated NRC Coating materials (biocides, abrasive particles, antimicrobials, metal ions, activated carbon, preservative agent, super absorbent, and so on) are applied on both or single surface of composites either permanently or temporarily to provide various functionalities.
-
Hybrid NRCs Knitted, braided, and woven fabrics, foams (with tissue), and films are combined with the nonwovens to develop a tri-layer composite by hydroentangling one woven fabric sheet between two nonwoven sheets.

SWOT analysis of laminated composites
Strength | Weaknesses |
---|---|
Laminated composites made of natural fibers like flax, hemp, sisal, and ramie providing sustainable features | Could generate weaker interfacial bonding if the fibers are not treated properly in composite systems |
Higher stiffness and strengths | Efficient innovations for large scale industrial production are lacking |
Larger production volumes | Inhomogeneous characteristics varying on fabric characteristics and design |
Bio-based laminates could be recycled | Need to combine two different production plants together like textiles for fabric and composite manufacturing companies for laminated composite productions together |
Providing superior strength in terms of hybrid composites made of natural and synthetic fabric reinforcements | Lack of efficient bio-based thermosetting/thermoplastic polymers |
Newer marketing potentially is being continuously created | Lack of efficient modeling availability |
Opportunities | Threats |
---|---|
Manufacturers and researchers are becoming more involved in laminated composites production | Nonhomogeneous quality of developed laminates, especially for natural fiber-based fabric composites |
Light weight, sustainable, and economic features | Higher prices of synthetic fabrics like carbon, glass, aramid etc., has made it difficult to ensure availability for reinforcing with bio-based fabrics |
Latest technological advancements are being implemented with continuous improvements from scientific methods and facilities | Current extreme dependency on wood particle/flour-based composites instead of laminations |
Natural fibers are available throughout the world, which could facilitate bio-based fabric-reinforced laminated composites manufacturing | Lack of specific technological equipment for manufacturing composites |
