Wind energy is an important clean energy, according to China's carbon peak and carbon neutral strategy, the policy of replacing small with large wind turbine blades and replacing old with new is imperative. The main material of wind turbine blades is glass fiber reinforced polymer, which has problems of difficult recycling technology and high recycling cost. Nowadays, there is no ideal large-scale recycling method. Therefore, the systematic and high-value utilization of waste wind turbine blades is imminent. In this paper, the material type, recycling methods and their respective characteristics of wind turbine blades are summarized. The recent developments of waste wind turbine blades in cement-based materials and thermoplastic polymer materials are thoroughly discussed. Overall, this paper can provide reference for the subsequent development and research on the recycling waste wind turbine blades. [ABSTRACT FROM AUTHOR]

The injection molding process of an automobile front-end frame was simulated, and the optimization of process parameter combination was explored with the goal of maximizing all effects deformation. Aiming at the problem of large deformation of the maximum all effects under the initial process, the orthogonal test was designed and the range and variance analysis were carried out. The results show that the injection time has the greatest influence on the deformation of the part, which is extremely significant. The influence of the surface temperature of the die cavity and the barrel temperature on the deformation of the part is significant. The influence of the filling volume percentage of the speed pressure switching on the deformation of the part is not significant, and the optimal process parameter combination is A2B2C2D3. The simulation results of the optimized process show that the maximum deformation of all effects is reduced to 2.949 mm, and the optimization range is large and meets the index requirements. The optimized process is used to test the mold. The trial sample is in good condition and the deformation amount meets the requirements, which verifies the rationality of the optimization scheme.

Binary copolymerized semi-aromatic polyamide (PA6T/66) is a kind of polymer material with low cost, high rigidity and mature process, but it has poor toughness and certain water absorption. PA6T/10T/66 resin was prepared by melt polymerization and micro-negative pressure viscosity enhancement by introducing high temperature resistant polyterephthaloyl decanediamine (PA10T) segment of aliphatic long carbon chain with low water absorption into PA6T/66 resin. The results show that the optimum amount of PA10T salt is 5% when preparing PA6T/10T/66 resin. Infrared spectra shows that PA6T/10T/66(45/5/50) resin is completely polymerized. The melting point of PA6T/10T/66(45/5/50) resin is 300 °C by differential scanning calorimeter (DSC). When the viscosity of the resin is 2.5, the tensile strength is 50 MPa and the flexural strength is 54 MPa. When the polymerization pressure is 2.35 MPa and the amount of end capping agent is 1.5% of the total salt mass, the viscosity of the resin meets the application requirements. This process has low cost and simple preparation process, and the obtained ternary copolymer resin is suitable for glass fiber modification, color matching, injection molding and other applications.

Aimed to expand applications of aramid fiber fabrics and provide a reference for select fibers for filter bags using in high temperature flue gas filtration, properties such as filtration performance, temperature resistance, wear resistance, folding endurance, corrosion resistance and flame retardance of aramid fibre needle punched nonwoven fabrics were measured, in comparison with polyimide fiber needle punched nonwoven fabrics and glass fiber woven fabrics. It is found that aramid fiber fabric exhibits excellent temperature resistance. The tensile strength remains unchanged after thermal treatment under 220 °C for 24 hours. The folding endurance and corrosion resistance are excellent. The filtration performance of fabrics composited with 1 D aramid fibers is excellent while its flame retardance and wear resistance should be improved by PTFE emulsion impregnation.

Based on computer aided engineering, the injection molding process of BMS control box of glass fiber reinforced PBT material was simulated, and the process parameters of the flatness of the screw column end face were optimized by orthogonal test. The results show that the injection time has the greatest influence on the flatness of the end face of the screw column, and the melt temperature has the least influence on the flatness. The optimized process to minimize the flatness of the screw end face is A3B2C3D2. Under the optimized process, the flatness of the end face of the screw column is reduced to 0.451 7 mm, and the optimization rate is 50.3%, which meets the design requirements. The simulation results of filling process, weld line and sink mark and the test results of sample all meet requirements, which verifies the rationality of the optimized process.

The injection molding process of a low-pressure connector was simulated and the optimization scheme of process parameters was explored. Based on the analysis of single point feeding scheme, the best gate position is obtained, and the hot runner system is established. Aiming at the problem that the maximum axial concentricity of the mounting hole exceeds the standard under the initial process conditions, an orthogonal test was designed to obtain the influence law of the process parameters. The results show that the optimized process parameter combination is A3B2C3D3E1F3. Through process optimization, the maximum axial concentricity of the low-voltage connector mounting hole is reduced by 35.2% and meets the target requirements. The availability of the optimized process is verified by simulation, actual test and installation test. [ABSTRACT FROM AUTHOR]

Glass fiber (GF) was modified by KH-550 to improve the compatibility between GF and epoxy resin (EP) matrix, and glass fiber reinforced epoxy resin composites (EP/GF) were prepared. The effects of GF content on the insulation and mechanical properties of EP/GF composites were studied. The results show that GF can be uniformly dispersed in EP when the content of GF does not exceed 30%. When the content of GF reaches 40%, GF agglomerates, and the EP matrix produces defects such as pores. When the content of GF is 30%, the insulation performance and comprehensive mechanical properties of EP/GF composites were the best. Compared with pure EP, the volume resistivity of the composites is increased by 36.9%, the relative dielectric constant ( εr) and dielectric loss factor (tan δ) are decreased by 11.4% and 8.9%, respectively. The short-term AC breakdown voltage value is increased by 27.8%, the bending strength is increased by 38.2%, the impact strength is increased by 40.0%, the tensile strength is increased by 40.4%, the elongation at break is decreased by 11.1%, and the hardness is increased by 5.9%.

Glass fiber reinforced polypropylene composite fiber was prepared by the experimental schemes of adding different mass fractions of glass fiber (reinforcing agent) and polypropylene grafting maleic anhydride (compatible agent), and modifying glass fiber surface and taking different spinning speeds. The study aims to explore the interface combination effect and long-term stability of glass and polypropylene, and realize the industrial preparation of glass fiber reinforced polypropylene composite fiber. The mechanical properties of the composite fiber were studied. The spinnability of the sample was determined by differential scanning calorimeter and melting index. The mechanism and effect of interface bonding between polypropylene and glass fiber modified by silane coupling agent KH550 were analyzed by infrared spectrometer and scanning electron microscope. The results of the mechanical tests show that the tensile strength of glass fiber reinforced polypropylene composite fiber increases 29.7% at most compared with pure polypropylene fiber. The plastic injection sample was prepared by secondary melting of glass fiber reinforced polypropylene. Its tensile strength, bending modulus increase, and impact resistance increase by 29.2%,37.5%,22.3% respectively, compared with the plastic injection sample prepared by pure polypropylene.
