carbon fiber Filled PEEK plate

Carbon fiber filled PEEK plate is an advanced high-performance thermoplastic material that combines the outstanding chemical resistance and thermal stability of polyetheretherketone with the stiffness and wear resistance of carbon fiber reinforcement. This composite is widely used in aerospace, medical, semiconductor, and oil & gas industries where metal replacement is critical. Compared to unfilled PEEK, the carbon fiber variant delivers up to three times higher modulus and significantly lower thermal expansion. Our portfolio also includes specialized formats that share this same backbone — PEEK CA30 sheets provide targeted 30% carbon fiber reinforcement for improved load-bearing capacity, while carbon fiber reinforced PEEK sheets cover a broader range of fiber loadings to meet diverse design requirements. For applications demanding the highest possible strength and dimension control under extreme heat, we recommend the closely related PEEK CF30 plate, which shares the same matrix but is optimized for machining precision components such as seal rings and insulators.

Engineers often choose <产品名字> when conventional metals or commodity plastics fail under aggressive chemical environments and continuous operating temperatures above 250°C. The carbon fiber filler not only increases compressive strength and hardness but also dramatically improves thermal conductivity, allowing heat to dissipate more evenly across bearing surfaces and dynamic seals. Unlike glass-filled grades, the carbon fiber variant exhibits superior fatigue resistance and lower moisture absorption, ensuring stable mechanical performance even after repeated autoclave sterilization cycles. In semiconductor wafer handling and IC test sockets, <产品名字> maintains tight flatness and electrical insulation characteristics across thousands of thermal cycles, directly reducing tool downtime and part replacement frequency.

Detailed Product Specifications

The standard carbon fiber filled PEEK plate we supply conforms to ASTM D6262 and typically contains 30% carbon fiber by weight. Below are representative physical and mechanical properties measured on 3 mm thick compression-molded sheet:

• Color: Black
• Reinforcement: 30% carbon fiber
• Surface finish: Smooth, both sides skived or ground as required
• Sheet size options: 300 mm × 300 mm up to 600 mm × 1200 mm
• Thickness range: 3 mm to 80 mm
• Certification: Include mill test certificate with each batch, traceable to resin lot number

Custom thicknesses and larger panel sizes are available upon request. All carbon fiber filled PEEK plates are produced under strict process control to minimize internal voids and guarantee uniform fiber dispersion. Each sheet is ultrasonically inspected and tested for porosity before shipment, supporting critical applications where failure is not an option.
