Composite Joining Methods: Types and Key Considerations
2025-09-01
Overview Composite joining technology is a critical yet relatively weak link in the design and manufacturing of composite structures. Due to the anisotropy, brittleness, and low interlaminar strength of composites, their joining design differs significantly from metallic structures and requires special attention. The main joining methods can be categorized into three groups: 1. Mechanical Joining ...

A Quick Guide to the Power of Glass Fiber Reinforcement
2025-09-15
When you pick up your phone, take apart an auto part, or look at a home appliance casing, you might not realize that hidden inside these seemingly ordinary plastic products lies a kind of “invisible rebar” — glass fiber (GF). From PP + 20% GF to PA + 60% GF, these reinforcing fibers quietly support the plastic matrix, much like steel bars inside concrete. Today, let’s uncover the mystery of long g...

A Brief Introduction to Carbon Fiber Reinforced PPS
2025-11-10
Long Carbon Fiber Reinforced PPS High-performance thermoplastic composites can replace metals. Although PEEK is regarded as the benchmark for engineering performance, reinforced PPS offers a truly cost-effective alternative. The demand for engineering thermoplastics such as PC and high-performance thermoplastics like PEEK is steadily increasing in industrial applications. These materials, when pro...

What Makes PEEK Superior to Other High-Performance Engineering Plastics
2025-11-11
PEEK (Polyether Ether Ketone) Material Overview Introduction PEEK (Polyether Ether Ketone) is a linear aromatic high-performance polymer with repeating units of –O–Ph–O–C(=O)–Ph– in its molecular backbone. It is a semi-crystalline thermoplastic and a high-performance specialty engineering plastic with numerous advantages over other specialty plastics. PEEK has a melting point of 334 °C, a softenin...

Plastic vs Steel: Understanding Strength-to-Weight and Stiffness-to-Weight
2025-12-23
Specific Strength & Specific Stiffness: The Engineering Logic Behind “Plastic Replacing Steel” Introduction: Rethinking Material Performance In discussions about “replacing steel with plastic,” one critical concept is often overlooked: material performance should not be judged by absolute values alone. The real question is not “which material is stronger,” but: under the same weight constraint...

Key Considerations for Injection Molding Long Fiber Reinforced Thermoplastics (LFRT)
2026-09-28
Long fiber reinforced thermoplastics (LFRT) are increasingly being used in injection molding applications where high mechanical performance is required. While LFRT technology can provide excellent strength, stiffness, and impact resistance, the processing method plays a critical role in determining the final performance that a molded part can achieve. To successfully mold LFRT, it is essential to ...

PP-LGF vs. PA-LGF: How to Choose the Right Material?
2026-10-27
Material Selection Guide PP-LGF vs. PA-LGF: How to Choose the Right Long Glass Fiber Reinforced Material Many people wonder why some automotive brake pedal brackets use PP-LGF instead of the more familiar PA-LGF (long glass fiber reinforced nylon). A common misconception among junior designers and purchasing professionals is that, since both materials contain glass fibers and can provide sufficien...
