40% Long Carbon Fiber Reinforced Homopolymer Polypropylene (LFT-G® PP-CF40)
LFT-G® PP CF40 is a high-performance long-fiber reinforced Homopolymer Polypropylene (LCF-PP) that offers superior stiffness, strength, and remarkable lightweighting capabilities compared to traditional short-fiber PP CF40. This advanced composite, featuring 40% long carbon fiber in an easily processable PP matrix, is engineered to elevate standard polypropylene into a true structural material. It stands as an ideal thermoplastic solution for significant weight reduction and performance enhancement in automotive interior frames, durable consumer electronics enclosures, and lightweight sports equipment. In short, this page details an engineering solution for superior strength-to-stiffness ratio, significant lightweighting, and excellent cost-effectiveness (LFT-G® PP CF40-BC04H) - blending the high performance of 40% long carbon fiber with the processability and economics of a Homopolymer Polypropylene matrix, ideal for next-generation automotive interior frames, consumer electronics enclosures, and lightweight high-performance sports goods.
Q: What is carbon fiber PP used for?
A: LFT-G® PP-CF40 is used for structural components that require high stiffness and low weight at an attractive price point, such as automotive interior frames, drone bodies, medical device housings, and high-performance luggage. Its combination of carbon fiber strength and PP's versatility is a key advantage.
Q: What are the key advantages of PP CF40?
A: LFT-G® PP-CF40 provides outstanding stiffness and strength (often comparable to metals on a specific gravity basis), excellent fatigue resistance, and superior dimensional stability compared to unreinforced PP. It offers significant weight reduction and lower system costs, making it a powerful alternative to heavier materials in automotive and consumer electronics.
Q: Can carbon fiber polypropylene replace metal?
A: Absolutely, especially in non-high-temperature structural applications. LFT-G® PP-CF40 can replace steel, aluminum, and even some engineering plastics by offering a superb strength-to-weight ratio, corrosion resistance, and simplified manufacturing through injection molding. This translates to lighter parts, reduced assembly steps, and overall cost savings for applications like sports goods and drone components.

This "Cost-Performance Balancer" illustrates LFT-G® PP-CF40's unique positioning. It significantly elevates the performance of standard polypropylene to challenge lightweight metals, offering a superior stiffness-to-weight ratio at a highly competitive cost, thereby achieving an optimal balance for demanding structural applications.
Case Study: Automotive Tailgate Interior Frame
The Challenge
An automotive OEM aimed to reduce the overall weight of their vehicle by redesigning the tailgate's interior structural frame. The existing solution, primarily made of steel and some short-fiber glass-reinforced PP, was heavy and required multiple assembly steps. The goal was to achieve substantial weight savings without compromising structural integrity, crash performance, or dimensional stability, all while maintaining competitive part costs.
The Solution: LFT-G® PP-CF40
Our LFT-G® PP-CF40 was selected for its exceptional stiffness-to-weight ratio and ease of processing. By leveraging 40% long carbon fiber reinforcement, the PP matrix provided the necessary structural rigidity and impact strength to meet stringent automotive safety standards. The injection molding process allowed for the consolidation of multiple components into a single, complex part, incorporating mounting features and cable routing directly. This eliminated several assembly steps and significantly reduced material mass compared to the previous metal/short-fiber solution.
Result: A 30% weight reduction for the tailgate interior frame, improved NVH (Noise, Vibration, Harshness) characteristics, and a 20% decrease in total manufacturing and assembly costs, directly contributing to vehicle fuel efficiency goals.
