Raw material PPS composite long glass fiber for home appliances parts

PPS-LGF

The resin matrix of long fiber reinforced thermoplastic composites involves general and special engineering plastics. Xiamen Long Fiber has been focusing on the field of LFT for more than ten years, with a complete variety, including PP, PA, MXD6, PPA, PC, PBT, TPU, PPS, PEEK, etc. PPS is a kind of thermoplastic special engineering plastics with excellent comprehensive performance, and is a typical representative of special engineering plastics, commonly known as "plastic gold".

PPS has excellent high temperature resistance, corrosion resistance, radiation resistance, flame retardant, balanced physical and mechanical properties, excellent dimensional stability and excellent electrical properties. Compared with other high performance thermoplastic engineering plastics PPS has the characteristics of easy processing, low cost and good adhesion with other materials, so it becomes an excellent resin matrix for manufacturing composite materials.

Performance

PPS material although has many advantages, but the pure PPS material is not only brittle, impact resistance is poor, and the processing is difficult, expensive. In order to improve these defects, we need to modify the PPS material. The modified PPS material can improve its thermal conductivity, wear resistance and high temperature resistance.

Compare with Short Glass Fiber

The reinforcement fibers added in the resin matrix can form a supporting skeleton, and the reinforcement fibers can effectively bear the external load when subjected to external force. At the same time, energy can be absorbed by fracture, deformation and other ways to improve the mechanical properties of resin.

Therefore, increasing the amount of glass fiber, its tensile strength and bending strength are gradually increased. The tensile and bending properties of PPS/LGF composites are higher than those of PPS/SGF composites. The tensile strength, bending strength and bending elastic modulus of PPS/LGF composites are increased by 11.0%, 18.9% and 11.3% compared with PPS/SGF composites, respectively. PPS/LGF composites have higher length retention rate of glass fiber. Under the condition of the same glass fiber content, the composites have stronger load resistance and better mechanical properties.

The impact performance of long glass fiber composites is 3-5 times stronger than that of short glass fiber composites. Moreover, with the increase of the glass fiber content, the glass fiber in the composite can form an effective spatial network, and the reinforcement effect is greater than that of the glass fiber tip. Under the action of external load, the external load can be transferred to the reinforced fiber better, thus improving the overall performance of the composite. In the PPS/LGF system, the glass fiber length is longer and the spatial network is more dense. The reinforced glass fiber has greater bearing capacity and better impact strength.

The introduction of glass fiber greatly improves the heat resistance of composite materials. The main reason is that the glass fiber forms a network skeleton of reinforced fiber inside the composite material, which greatly improves its heat resistance. The longer size of the glass fiber in PPS/LGF makes the heat resistance improvement more obvious.

With the increase of glass fiber content, the construction of reinforced fiber network inside the composite becomes more perfect. This is also the main reason that the overall mechanical properties of composites increase with the increase of glass fiber content. Compared with PPS/SGF and PPS/LGF composites, the glass fiber retention rate of PPS/LGF composites is higher, which is also the main reason for the better mechanical properties of PPS/LGF composites.

In conclusion, the mechanical properties of PPS/LGF are improved by 2-5 times compared with PPS/SGF materials. The tensile strength, bending strength, bending elastic modulus, notched impact strength and unnotched impact strength are all improved compared with PPS/SGF materials.
