Materials
Understanding the material is designing the performance.
The descriptions below are general engineering knowledge. They make no claim about specific grades, values or certificates.
01 / 05
Procedural texture, illustrative only.
Carbon fiber
The core material of lightweight structures, valued for low density, high specific strength and stiffness.
Key characteristics
- High specific strength and stiffness
- Low weight
- Good fatigue behavior
Considerations
- Cost
- Brittle damage behavior
- Galvanic corrosion risk in contact with metals
Typical applications
Automotive body and structural parts · Aerospace structures · Sports and performance equipment
02 / 05
Procedural texture, illustrative only.
Fiberglass
A versatile, economical reinforcement that adapts to many geometries.
Key characteristics
- Manufacturing flexibility
- Electrical insulation
- Cost efficiency
Considerations
- Heavier and less stiff than carbon fiber
- Weave selection depends on application
Typical applications
Panels and body parts · Housings and covers · General industrial components
03 / 05
Procedural texture, illustrative only.
Aramid / Kevlar
A tough fiber for applications that demand impact resistance, abrasion resistance and energy absorption.
Key characteristics
- High toughness
- Impact and damage tolerance
- Low density
Considerations
- Cutting and machining need special methods
- Compressive behavior is lower than tensile
- Moisture effects must be considered
Typical applications
Impact-exposed components · Protective structures · Hybrid laminates
04 / 05
Procedural texture, illustrative only.
Epoxy resin systems
The matrix that holds fibers together and transfers load between them; a common choice for performance-oriented applications.
Key characteristics
- Good adhesion to fibers
- Strong mechanical behavior
- Low cure shrinkage
Considerations
- Cure and temperature schedule affect results
- Mix ratio and working time must be controlled
Typical applications
Carbon and aramid laminates · Structural parts · Tooling and mold applications
05 / 05
Procedural texture, illustrative only.
Polyester resin systems
An economical, easy-to-process matrix widely used with fiberglass.
Key characteristics
- Cost efficiency
- Easy to apply
- Wide availability
Considerations
- Higher shrinkage than epoxy
- Adhesion and mechanical behavior generally trail epoxy
- Ventilation is required in the work area
Typical applications
Fiberglass panels · General-purpose composite parts · Cost-sensitive applications
Mechanical values vary with fiber type, weave, resin, fiber volume fraction and process. They are defined and tested on a project basis.
