Why long fiber is preferred as reinforcement compared to short fiber
What is lFT composites?
Long fiber composite has emerged as a popular choice for many industries due to their exceptional mechanical properties and cost-effectiveness. They are preferred over short fiber composite as reinforcement for a variety of reasons.
To begin with, let us understand what is long and short fiber composite. Long fiber composite, as the name suggests, contains long fibers which could be continuous or discontinuous. On the other hand, short fiber composite contains short fibers, usually less than one inch in length, which are randomly oriented.
Benefit of LFT Long Fiber composites
------
The first advantage of long fiber composite over short fiber is their enhanced mechanical properties. Long fibers provide a high degree of directional strength and stiffness, which results in enhanced impact resistance, fatigue resistance, and durability of the composite material. Long fibers display better interfacial bonding with the matrix material, leading to improved mechanical properties compared to their short fiber counterparts. This makes them an ideal choice for high-performance applications where strength and durability are critical factors.
The second advantage of long fiber composite is their cost-effectiveness. Long fibers are easier to process since they are continuous and can be mechanically aligned. This results in reduction of labor and processing costs compared to short fibers, which have to be aligned through other means like injection molding. Moreover, long fiber composite provides excellent dimensional stability and reproducibility, reducing the need for costly quality control measures.
Products Application
long fiber composite is preferred as reinforcement compared to short fiber due to their enhanced mechanical properties, cost-effectiveness, thermal stability, and design flexibility. With their superior properties, long fiber composites are now widely used in various industries such as automotive, aerospace, and construction. As technology advances, we can expect to see more research and development in this field, leading to even more superior composite materials.
Outstanding Case Sharing
In 2021, a customer making home appliance parts approached us and said, "The PP-GF material we are using now has insufficient performance, and we need a high-performance material to improve the strength and toughness product performance of washing machine parts."
After evaluating the proposal from our technical department, we suggested the customer to use "LFT-G® PP-NG05-LGF50% mix PP raw resin to make the composite material. After our reasonable technical guidance, the mechanical properties of the washing machine parts made of our LFT-G® PP-NG05-LGF50% material were improved by 30%-40%. The customer's feedback is very satisfied with the use of the results, for the customer in the target country market to obtain a great market advantage. We have exported more than 2,000MT material to our customers, and we are able to provide our customers with continuous and stable supply.
