Laminates & Composites

Laminates and composites combine two or more materials, layers, or reinforcing elements to provide properties that a single material may not offer on its own. Depending on the construction, they may be selected for dimensional stability, low weight, surface protection, electrical isolation, structural support, or resistance to specific environmental conditions.

This K-Catalog category is part of Raw Materials and provides a focused way to compare available laminates and composites. Product pages can help you check the construction, size, thickness, finish, and other specifications that affect fit and performance.

How to choose laminates and composites

Start with the job the material must perform rather than with the material name alone. A decorative or protective laminate may have different priorities from a reinforced composite used as a structural component. Consider:

• Function: Decide whether the material is intended for insulation, reinforcement, surfacing, fabrication, repair, or general material replacement.
• Strength and stiffness: Compare the listed mechanical properties when the part will carry a load, resist bending, or maintain a fixed shape.
• Weight: A composite may be useful when reducing mass matters, but its strength-to-weight characteristics should be evaluated for the specific application.
• Environment: Check whether the listed material is suitable for moisture, chemicals, temperature changes, abrasion, or outdoor exposure.
• Fabrication needs: Cutting, drilling, bonding, sanding, and finishing requirements can vary substantially between laminate constructions.
• Dimensions: Confirm sheet, plate, panel, strip, or other form factors, along with thickness and tolerance information where provided.

If the application involves safety-critical loads, heat, pressure, or electrical performance, use the manufacturer’s technical documentation to confirm suitability before ordering.

Common laminate and composite constructions

The category does not currently have separate catalog subcategories, so comparing products by construction is especially useful. Laminates are often made by bonding layers together, with each layer contributing a particular surface, barrier, or mechanical property. Composite materials typically combine a matrix or binder with reinforcement such as fibers, fabric, or other fillers.

Fiber-reinforced materials

Fiber-reinforced composites can be chosen when stiffness, strength, or low weight is important. Compare the reinforcement type, orientation, weave or layup, resin or matrix, thickness, and supplied form. These details can influence how the material behaves when cut, drilled, fastened, or loaded.

Carbon and hybrid composites

Carbon-based materials are commonly evaluated for rigidity and weight efficiency, while hybrid constructions may combine more than one reinforcement type. Look for details about the fiber or fabric construction, surface finish, resin system, and whether the item is intended as a finished panel, raw sheet, fabric, or fabrication component.

Surface laminates and bonded sheets

For laminates used as a facing, barrier, or finished surface, compare the core and outer layer, finish, bonding method, thickness, and resistance properties. The appearance and texture may matter as much as the underlying material when the laminate will remain visible.

Specifications and compatibility to compare

Product specifications should be read together rather than in isolation. A thicker sheet may provide greater rigidity, but it may also require different cutting tools, fasteners, edge treatment, or clearance. Dimensions should be checked against the available workspace and the required finished part size.

Also compare the following details when listed:

• Material composition and reinforcement type
• Sheet, panel, roll, or other product form
• Thickness, length, width, and dimensional tolerances
• Surface finish, color, weave, or orientation
• Temperature, chemical, moisture, and electrical properties
• Recommended adhesive, resin, sealant, or finishing method
• Cutting, drilling, storage, and handling guidance

Compatibility is important when joining a composite to metal, plastic, rubber, wood, or another laminate. The adhesive, fastener, sealant, and surface-preparation method can affect the finished assembly as much as the base material.

Related raw materials

Depending on the project, a laminate or composite may be compared with other raw materials. Browse Metals & Alloys when conductivity, heat transfer, hardness, or metal fabrication characteristics are important. Plastics may be a better comparison for molded, machined, or chemically resistant parts, while Rubber is relevant when flexibility, sealing, or vibration control is needed.

For reinforcement and open structures, see Mesh & Wire Cloth. Wood can be useful for natural or engineered sheet materials, and Shims & Shim Stock may suit precise spacing, leveling, or adjustment applications.

Frequently asked questions

What is the difference between a laminate and a composite?

A laminate is generally made by bonding layers together, while a composite combines a matrix with reinforcement or filler. Some materials can be described using both terms, depending on their construction.

How do I select the right thickness?

Choose thickness based on the required stiffness, clearance, load, insulation, or surface coverage. Confirm the finished dimensions and fabrication method before selecting a product.

Can laminates and composites be cut or drilled?

Many can be fabricated, but the correct tools, cutting speed, dust control, and edge treatment depend on the material. Follow the manufacturer’s guidance and use appropriate protective equipment.

What should I check before bonding a composite?

Check surface preparation, adhesive compatibility, cure conditions, service temperature, and the materials being joined. A test assembly may be appropriate when the bond is important to performance or safety.
