Fiberbonded

Fiberbonded is a term used to describe materials in which fibers are bonded by a matrix or adhesive to form a cohesive solid. It encompasses both fiber-reinforced composites and nonwoven fiber-bonded sheets, where the common goal is to combine the properties of fibers with a binding medium to achieve improved performance.

In fiber-reinforced composites, fibers such as glass, carbon, or aramid are embedded in a resin matrix (thermoset or thermoplastic). The matrix binds the fibers, transfers loads, and protects them from environmental damage, while the fibers provide high strength and stiffness. Common manufacturing methods include resin transfer molding, lay-up, and pultrusion. The resulting materials offer high strength-to-weight ratios, tailored anisotropy, and corrosion resistance, and are used in aerospace, automotive, sports equipment, and construction.

Nonwoven fiber-bonded materials are produced by bonding fibers into a coherent sheet or web through mechanical, thermal, or adhesive processes. Techniques such as needle-punching, thermal bonding, or adhesive bonding create products used in filtration, insulation, sound dampening, and certain automotive components. These materials emphasize cost-efficient production and versatile forming, often with less directional dependence than continuous-fiber composites.

Advantages of fiberbonded materials include high specific strength and stiffness, durability, and design flexibility. Limitations can involve higher material costs, complex processing, and environmental considerations related to resin systems and fiber sources. Recycling and end-of-life disposal vary by matrix and fiber type and are active areas of development.
