High performance fibers exhibit extraordinary mechanical properties. These high performance materials are made of ceramics, metals, carbon, and polymers. High performance polymer fibers integrate excellent mechanical properties with low weight.
High tensile strength and high resilience are the two main properties of the high-performance fibers. For some polymer materials, high tensile strength can be obtained using high drawing ratios and high molecular orientation (e.g. for Aramid / Kevlar) during the process of fabrication.
What are high performance fibers?
High performance fibers are designed to protect the body by having unique properties. Highly innovative and smart textiles can be related to protection and survival in hostile environments. It takes knowledge and understanding of high-performance fibers to produce these fabrics. When primary fibers are spun into a parallel aligned, highly oriented fiber bundle or yarn, high strength and high durability can be reached, and then stably linked in the highest orientation state.
The high degree of orientation leads to high resistance to tensile, and the secure connections that lead to high resistance. They could produce very uniformly oriented, crystalline yarns using electro-spinning, which is a subsequent concerted process at higher temperatures. It gets drawn to the highest orientation and covalently interlinked in the drawn state.
The different kinds of applications of high performance fibers
Aerospace & Defense
Military use of advanced polymer matrix composites (PMC), which is a resin matrix reinforced by high-performance carbon or organic fibers, reports nearly less than 10% of the domestic market. Nonetheless, in future military systems, advanced composites are projected to play an even greater role and DOD will continue to need access to reliable sources of inexpensive, high-performance fibers like industrial materials and manufacturing processes.
It is important to evaluate the challenges and opportunities linked with advanced PMCs with a focus on high-performance fibers as a result of these predictions. With potential in commercial aircraft, regional aircraft, aircraft, general aviation, UAV and others, the role of carbon fiber in the aerospace and defense industry looks promising.
The nanofibers have a very high surface-to-volume ratio and are finding useful applications in tissue engineering, optoelectronic devices, protective textiles and filters of the next generation. Significant demands on good performance properties-such as strength/modulus, resilience, and dimensional stability and on functions such as flame-retardancy, hydrophilicity, hydrophobicity, biocompatibility, smart and flexible textiles, etc.
Glass fiber is the oldest high-performance material and is the most prevalent one. The early versions were high-strength; they were fairly inflexible and unfit for several textile uses. Today’s glass fibers provide a much broader range of properties and can be used in many end applications, such as insulation tossing, fire-resistant fabrics, and plastic composite reinforcement materials.
With economic development, the living standards of individuals are raising, with more modern people engaging in sports venues of all kinds. Also, the development of modern physical sports in the sports experts simultaneously focuses on scientific training, also attaches great importance to improving and developing sports equipment.
The widespread adoption in sports equipment has been associated with the prevalence of fiber-reinforced composite materials with lightweight, high strength, broad degrees of design flexibility, simple processing and shaping characteristics. Several sports equipment rely on humans to make the movement easier, the lighter the better, so it includes equipment like tennis rackets, golf clubs, bikes, skis, etc. In this respect, reinforced fiber composites have incomparable advantages. Examples include golf clubs made of carbon fiber reinforced materials, that adopt the take-up molding in carbon fiber cloth, mechanical properties of a metal rod improved many, 30%-50% and the weight is lower than the metal rod.
What’s trending in the high performance fibers industry?
Recent developments in carbon fiber production
Carbon fibers with different cross-sections have also recently been developed by different organizations. There were two fundamental benefits to such a modification. The first benefit being the utilization of hollow carbon fibers, which can help in reducing the density of carbon fiber in composites. The strongest hollow carbon fibers were developed by carbonizing hollow PAN fibers spun from a C-shaped spinnerette.
Another benefit may be an improvement in the surface area, which potentially improves the overall resin interface. Recent developments and improvements in high-performance fibers with a wide range of properties have made it more possible to withstand harsh operating environments for a wide range of applications, like aerospace, aircraft, airline, medical, automobile, oil, transport and so on.
Investments in fiber technology
A few industries are continuing to invest in new carbon fiber technologies. This investment was mainly in process improvement and better manufacturing controls to minimize uncertainty and reduce costs rather than upgrade properties. As a result of this phenomenon, any change in carbon fiber properties is likely to be evolutionary.
In the organic fiber industry, M5 fiber has the potential to become a commercial fiber with a gradual improvement in functionality, in particular, to meet the need for optimized structural and ballistic properties of interest to DoD. M5 can fulfill the Army’s future logistical and ballistic needs. Existing fibers, such as Kevlar, have good ballistic properties but weak compression properties. M5 could be an effective technology for a new generation of military protection systems.
High tenacity aramide fiber
Aramids are related to nylons and are polyamides produced from the amines and aromatic acids. Aramids show higher tensile strength and thermal resistance as compared to aliphatic polyamides (nylons) due to the flexibility of the aromatic rings and the additional strength of the amide links, due to the conjugation with aromatic structures. Depending upon terephthalic acid and p-phenylene diamine, or paminobenzoic acid, the para-aramids show higher strength and thermal tolerance than meta-position linkages on the benzene rings.
Combined with the greater chain orientation resulting from this linearity, the greater degree of conjugation and more linear structure of the para linkages are mainly responsible for the greater strength. The para-aramids’ high impact resistance makes them famous for body armor which is “bulletproof.” The aramids may be combined with other fibers for several less demanding applications.
