Types of Industrial Composite Parts
Diversity in Design, Efficiency in Performance
In the modern industrial era , composites have emerged as lightweight , durable , and designable materials that replace traditional materials like metals in
many applications. The combination of reinforcing fibers (such as glass, carbon, or aramid) with a polymeric , ceramic , or metallic matrix enables the
production of components with engineered and customizable properties.
Composite parts are now used in a wide range of industries and are categorized based on their structure, performance, production method, and constituent
materials. In this article, we provide a clear picture of the types of industrial composite parts by exploring detailed classifications and application examples.
Classification Based on Type of Reinforcing Fiber
A) Glass Fiber Composites (GFRP)
Features: Cost-effective, moderate mechanical strength, electrical insulation
Applications: Transmission pipes, construction components, wind turbine blades, electrical panels
B) Carbon Fiber Composites (CFRP)
Features: High strength, lightweight, excellent thermal and fatigue resistance
Applications: Aircraft, racing car parts, space structures, medical prosthetics
C) Aramid Fiber Composites (Kevlar)
Features: High impact and abrasion resistance, lightweight
Applications: Bulletproof vests, helicopter blades, safety equipment, protective coatings
D) Hybrid Composites
A combination of different fiber types (e.g., glass + carbon) for optimized properties
Classification Based on Type of Matrix (Resin or Base)
A) Polymer Matrix Composites (PRC)
The most widely used type, includes epoxy, vinyl ester, polyester resins
Suitable for construction, automotive, medical, electrical, and aerospace applications
B) Metal Matrix Composites (MMC)
Metal matrix (aluminum, titanium) with ceramic or carbon fibers
Used in high-temperature, high-hardness applications like aircraft engine components
C) Ceramic Matrix Composites (CMC)
Suitable for high temperatures, oxidation and corrosion-resistant
Used in aircraft brakes, gas turbines, space equipment
Classification Based on Shape and Structure
A) Laminate Parts
Composed of various fiber layers
Can be designed for specific stress distribution
Used in airplane wings, reinforcement plates, building panels
B) Hollow and Tank Parts
Produced via Filament Winding or RTM
Includes CNG tanks, high-pressure pipes, hollow shafts
C) Sandwich-Structured Parts
Contain a lightweight core (foam or honeycomb) between two reinforced layers
Applications include aircraft floors, doors, wall panels, architectural structures
D) Injection or Molded Parts
Produced using resin injection processes, suitable for complex shapes
Used in pump impellers, car decorative components, industrial casings
Classification Based on Production Method
Hand Lay-Up
Used for simple, low-volume parts
Examples: reinforcement plates, construction parts, lab equipment
RTM (Resin Transfer Molding)
Suitable for complex, high-precision parts
Examples: car bumpers, industrial equipment shells, electronic cases
Pultrusion
Continuous production of fixed-profile parts like angles, beams, and pipes
Used in bridges, warehouses, structural reinforcement
Filament Winding
For pressurized tanks, gas transmission pipes, robot booms and shafts
Compression Molding
Used for dense molded parts; common in automotive and electrical industries
Classification Based on Industrial Application
Aerospace
Wings, tails, fuselage, engine covers, turbine blades, radomes
Must withstand fatigue, be lightweight, and tolerate high temperatures
Automotive
Bumpers, hoods, doors, chassis, decorative parts
Composites reduce weight and improve fuel efficiency
Oil, Gas, and Petrochemical
Pipes, flanges, tanks, nozzles, anti-corrosion coatings
GFRP and CFRP are used to reduce corrosion and increase lifespan
