Carbon Fiber chopped strand Mat

short description:

A carbon fiber mat (or carbon fibre mat) is a non-woven fabric composed of randomly oriented, short carbon fibers held together by a chemical binder or needling process. Unlike woven carbon fabrics, which have a distinct directional pattern, the mat’s random fiber orientation provides uniform, quasi-isotropic properties, meaning it has strength and stiffness in all directions within its plane.

Introduction

Property

Multi-Directional Strength: The random fiber orientation distributes loads evenly in all directions, preventing weak points and ensuring consistent performance.

Excellent Conformability & Drape: Carbon fiber mats are highly flexible and can easily conform to complex curves and molds, making them ideal for parts with intricate shapes.

High Surface Area: The porous, felt-like structure allows for rapid resin wet-out and high resin absorption, promoting a strong fiber-to-matrix bond.

Good Thermal Insulation: With high carbon content and a porous structure, carbon fiber mat exhibits low thermal conductivity, making it suitable for high-temperature insulation applications.

Electrical Conductivity: It provides reliable electromagnetic interference (EMI) shielding and can be used for creating static-dissipative surfaces.

Cost-Effectiveness: The manufacturing process is less labor-intensive than weaving, making it a more economical option for many projects compared to woven fabrics

Application

Composite Parts Manufacturing:Vacuum Infusion & Resin Transfer Molding (RTM): Often used as a core layer to provide bulk and multi-directional strength, combined with woven fabrics.

Hand Lay-Up & Spray-Up: Its excellent resin compatibility and ease of handling make it a primary choice for these open-mold processes.

Sheet Molding Compound (SMC): Chopped mat is a key ingredient in SMC for automotive and electrical components.

Thermal Insulation:Used in high-temperature furnaces, vacuum furnaces, and aerospace components as a lightweight, durable insulation material.

Electromagnetic Interference (EMI) Shielding:Integrated into electronic enclosures and housings to block or absorb electromagnetic radiation.

Fuel Cell & Battery Components:Serves as a gas diffusion layer (GDL) in fuel cells and as a conductive substrate in advanced battery systems.

Consumer Goods:Used in the production of sporting goods, musical instrument cases, and automotive interior parts where a Class A surface finish is not the primary requirement.
