PLA Plastic | Long Glass Fiber Reinforced PLA (PLA-LGF) What is PLA? Polylactic acid (PLA) is a biodegradable and eco-friendly polymer plastic, produced via pollution-free processes. PLA can naturally degrade and recycle in the environment, making it an ideal green polymer material and one of the most representative biodegradable plastics. PLA Structure and Heat Resistance The molecular structure of PLA affects its heat resistance, toughness, mechanical strength, degradability, and biocompatibility. PLA has a spiral molecular chain with low activity, resulting in slow crystallization after injection molding and relatively poor heat resistance. During hot processing, ester bonds may break partially, generating terminal carboxyl groups that accelerate thermal degradation. Long Glass Fiber (LGF) Reinforced PLA Reinforcing PLA with long glass fibers (PLA-LGF) improves mechanical strength, rigidity, and heat resistance. The fibers act as skeleton support, restricting polymer chain movement during heating and increasing thermal stability. Types of Fibers for PLA Reinforcement Fibers used for PLA enhancement include: Natural plant fibers: sisal, flax, linen, bamboo, coconut, wood fiber Animal fibers: silk Mineral fibers: basalt fiber Chemical fibers: glass fiber, carbon fiber Glass fiber and carbon fiber are widely used due to their high strength and modulus, while natural fibers are favored for biodegradability and renewable sources. Modified fibers blended with PLA have shown Vicat softening temperatures exceeding 140°C. Compared with Short Fiber (SGF) Long glass fiber reinforced PLA demonstrates superior mechanical properties compared with short fiber (SGF) reinforced PLA. It is more suitable for large structural parts, offering 1–3 times higher toughness and 0.5–1 times greater tensile strength and rigidity.

Long Carbon Fiber Carbon fiber exhibits outstanding properties, including extremely high axial strength and modulus, low density, and excellent specific performance. It shows no creep, outstanding fatigue resistance, excellent corrosion resistance, and maintains stability at very high temperatures in non-oxidizing environments. Carbon fiber also features good electrical and thermal conductivity, effective electromagnetic shielding, a low coefficient of thermal expansion, and strong anisotropy. Compared with traditional glass fiber, carbon fiber offers more than three times the Young’s modulus and approximately twice the modulus of aramid (Kevlar) fiber. It is insoluble and does not swell in organic solvents, acids, or alkalis, making it highly suitable for corrosive and demanding environments. One effective way to reduce the cost of carbon fiber applications is to combine it with engineering plastics such as nylon, creating high-performance composite materials with optimized cost-performance balance. As a result, carbon fiber reinforced nylon has become an important material system in modern composite engineering. Nylon itself is a high-performance engineering plastic, but it suffers from moisture absorption, limited dimensional stability, and mechanical properties far below those of metals. To overcome these limitations, fiber reinforcement has been applied since the 1970s. Carbon fiber reinforced nylon significantly improves strength, stiffness, thermal stability, creep resistance, wear resistance, and dimensional accuracy. Compared with glass fiber reinforced nylon, carbon fiber reinforced nylon offers superior damping behavior and overall mechanical performance. Therefore, carbon fiber reinforced nylon (CF/PA) composites have developed rapidly in recent years. In particular, for additive manufacturing, SLS (Selective Laser Sintering) technology is considered one of the most suitable methods for processing carbon fiber reinforced nylon materials.

PA6 Material Overview PA6 (Polyamide 6) is a widely used engineering plastic with excellent balanced performance. Its raw materials are readily available and cost-effective, making it accessible without dependence on foreign technology. However, PA6 has some limitations such as high water absorption, lower low-temperature impact toughness, and moderate dimensional stability. To overcome these limitations, PA6 is often reinforced with glass fiber (GF) to enhance mechanical properties. PA6-LGF (Long Glass Fiber Reinforced PA6) 1. Influence of Glass Fiber Content Glass fiber content is a key factor in the performance of reinforced composites. Increasing fiber content increases fiber density, thinning the PA6 matrix between fibers. This enhances impact toughness, tensile strength, and bending strength. Example: For PA6-LGF, increasing fiber content to 35% raised notch impact strength from 24.8 J/m to 128.5 J/m. However, excessive fiber content can reduce impact strength. Bending strength also improves as fibers transfer stress and absorb energy when broken, with experimental results showing bending modulus up to 4.99 GPa for 35% LGF. 2. Influence of Fiber Retention Length Fiber length significantly affects mechanical properties. When fiber length is below the critical length, increasing length improves resin-fiber bonding and tensile load resistance. When fiber exceeds the critical length, longer fibers absorb more impact energy and improve impact strength, as the number of fiber ends (crack initiation points) decreases. Example: At 40% fiber content, increasing fiber length from 4mm to 13mm improved tensile strength from 154.8 MPa to 164.4 MPa, with bending strength and notched impact strength increasing by 24% and 28%, respectively. Fibers longer than 7mm enhance warping resistance and mechanical stability under high temperature and humidity. Technical Data Reference (TDS) PA6-LGF can be reinforced with 20%-60% long glass fiber depending on product requirements. Compared to unreinforced PA6, PA6-LGF offers enhanced strength, heat resistance, impact resistance, dimensional stability, and reduced warping. The following TDS shows the data for PA6-LGF30. Applications of PA6-LGF PA6-LGF is widely used in automotive, electronic/electrical, and machinery/engineering parts. Automotive Parts Lightweight and miniaturization trends promote PA6-LGF use in engines, electrical systems, and body components. Electronic & Electrical Components Excellent flame retardancy and corrosion resistance make PA6-LGF suitable for switchgear, circuit breakers, contactors, connectors, and cable protection tubes. Mechanical & Engineering Parts Good impact resistance, wear resistance, and self-lubrication properties allow PA6-LGF to be used in machinery and engineering accessories.

It takes less energy to produce PLA than petroleum-based thermoplastics, making it relatively eco-friendly. PLA is often regarded as being biodegradable.

PLA Plastic PLA (polylactic acid) is a bio-based polyester and one of the most promising "green plastics" due to its biodegradability, biocompatibility, and high mechanical strength. PLA products can fully degrade into CO₂ and water via microorganisms, and are non-toxic and non-irritating. Mechanically, PLA is comparable to polypropylene, while its gloss, clarity, and processability resemble polystyrene. Its lower processing temperature allows production via injection molding, extrusion, blow molding, spinning, and other common plastic processing methods. PLA is widely applied in disposable plastics, packaging, fibers, nonwovens, chemical, medical, pharmaceutical, and 3D printing industries. PLA is increasingly recognized as a key material to reduce plastic pollution. PLA Reinforced Plastic Glass fiber (fiberglass) is an inorganic material with excellent insulation, heat resistance, corrosion resistance, and high mechanical strength. It is widely used to reinforce composite materials. Long glass fibers are typically over 10mm in length. Long Glass Fiber Reinforced PLA (LGFPLA) contains 10–25mm glass fibers forming a 3D structure during molding. It belongs to long fiber thermoplastics (LFT). Pellet sizes are generally 12mm (injection molding) or 25mm (compression molding). Glass fiber content ranges from 20% to 60%, and colors can be customized.
