Advancements in Fiber Reinforced Thermoplastic Composites: Applications, Performance, and Future Prospects

Thermoplastic plastics are a widely used type of plastic, primarily composed of thermoplastic resins and prepared by adding various additives.

By modifying the plastic and introducing fiber-reinforced materials, the performance of ordinary plastics can be significantly improved.

Therefore, fiber reinforced thermoplastic composites materials must possess characteristics such as high strength, low elongation, good rigidity, low creep, and excellent heat resistance.

Common continuous fibers include fiberglass, carbon fiber, basalt fiber, and aramid fiber.

These materials have features like low density, high strength, ease of processing, and recyclability.

Compared to thermoset prepreg composites, thermoplastic composites offer better adaptability and economic benefits during processing and maintenance.

They are widely used in aerospace, automotive manufacturing, construction, and sports equipment. In recent years, thermoplastic composites have received increasing attention due to their environmental and sustainability attributes.

Thermoplastic carbon fiber UD prepreg machine

Depending on the form of fiber reinforcement, thermoplastic composites have evolved through main stages such as short fiber reinforcement, long fiber reinforcement, and continuous fiber reinforcement.

Short fiber-reinforced thermoplastic composites (SFT) typically refer to thermoplastics with fiber lengths less than 1mm, generally ranging from 0.2-0.7mm. These composites are usually made into pellets with fiber lengths of 2-4mm.

In long fiber-reinforced thermoplastic composites (LFT), the reinforcing fibers are uniformly dispersed in the thermoplastic matrix during molding and can be fully impregnated.

The length of the reinforcing fibers is typically 10-50mm. The development of LFT has been primarily driven by the automotive industry, with good potential for growth in consumer and industrial markets.


In automotive glass fiber-reinforced plastics, long glass fiber-reinforced polypropylene (LGFPP) has garnered significant attention.

As a material for automotive module carriers, LGFPP not only enhances the rigidity, impact strength, creep resistance, and dimensional stability of products but also allows for the manufacture of complex automotive module products.

Compared to traditional materials, LGFPP offers better overall performance and can achieve part integration through improved injection molding processes, thereby reducing weight and cost.

However, during injection molding, glass fibers may be damaged, affecting their strength.

To fully leverage the reinforcing effect of glass fibers in plastics, their length must exceed the critical length.

Research indicates that when fiber length is below the critical length, fibers are prone to pull-out under load, thereby failing to fully exert their strength.

Therefore, the development and application of long glass fiber-reinforced polypropylene(PP) and its injection molding technology are crucial.

Continuous fiber reinforced thermoplastic composites (CFRT) have nearly 30 years of development history and represent an extension and advancement of pure plastics, SFT, and LFT.

Compared to SFT and LFT, CFRT offers significant advantages in structural performance, impact resistance, corrosion resistance, molding cycle, cost, and sustainability.

Glass fibers and carbon fiber are the primary reinforcing materials, while high-performance resins such as PA, PP, PET, PC, PEEK, and PPS are commonly chosen as matrices.


In recent years, with the continuous development of the thermoplastic plastics industry in China, the domestic fiber-reinforced thermoplastics industry has also shown a positive development trend.

Data indicate that in 2016, China’s production of fiber-reinforced thermoplastic products was 1.965 million tons, an increase of 11.39% year-on-year, accounting for 42.5% of the total production of fiber-reinforced plastic products in the country.

Thermoplastic composites can replace a variety of materials in automotive, aerospace, defense, transportation, and electrical and electronics sectors, including die-cast parts, metal assemblies, and industrial equipment.

Their high impact strength, superior surface quality, and good cost-performance ratio make them widely used across various industries.

Fiber reinforcement modification is one of the common modification techniques aimed at improving the mechanical properties of plastics.

Glass fibers and carbon fibers are commonly used reinforcing materials.

The mechanical properties of fiber-reinforced plastics depend on the type, length, content of the fibers, and their interface bonding with the resin, as well as the preparation process.

Compared to short fibers, continuous fibers and fiber fabrics provide more significant enhancements to the mechanical properties of plastics, but their preparation process is more complex.

Adequate impregnation of continuous fibers and fiber fabrics with the plastic resin is crucial for successful preparation.

In automotive plastic components, polypropylene(PP) is one of the most widely used and rapidly developing plastics.

PP thermoplastic resin

This is not only because polypropylene has advantages such as low density, low cost, high production volume, good cost-performance ratio, chemical stability, ease of processing, and recyclability, but also because it can be modified through copolymerization, blending, and filling reinforcement to meet the performance requirements of different automotive components.

Compared to short fibers, continuous fiber reinforced thermoplastic(CFRT) composites offer higher comprehensive mechanical properties and have become research and development focuses in automotive manufacturing, rail transportation, and aerospace sectors.

UD prepreg machine

Fiber fabrics can provide multi-directional reinforcement to plastics on a two-dimensional or three-dimensional scale.

Compared to thermoset prepreg, they have shorter molding cycles, lower manufacturing costs, and can be recycled multiple times, making them increasingly used in automotive and other fields.

Besides carbon fiber and glass fiber, basalt fiber(BF) can also be used to reinforce polyamide materials.

Researchers have prepared PA6/BF composites using environmentally friendly basalt fibers as reinforcing materials to address the poor interface bonding between the fibers and the resin matrix.

Currently, there are multiple grades of polypropylene materials available for automotive parts, suitable for manufacturing various components such as bumpers, dashboards, steering wheels, door panels, engine cooling fans, and body heating components.

Nevertheless, to meet higher requirements for aesthetics, comfort, safety, corrosion resistance, and lightweighting in high-quality automobiles, continuous research and modification of polypropylene materials are being conducted.
