Embodiment 1
[0032] A moldable high-performance thermoplastic composite material with a single fiber length distribution, calculated in parts by weight, comprises the following components: 50 parts of glass fiber filaments; and 50 parts of resin.
[0033]In this embodiment, 2400tex glass fiber filaments are used, polypropylene is used as the resin, the melt index is 25g / 10min, the glass fiber mass fraction is 50±5wt%, and the LFT-G particle length is 25mm. The LFT-G plate is heated and baked at 230°C, and then molded to obtain a product.
[0034] The tensile strength, flexural strength test and fiber length characterization of the prepared parts were carried out. The tensile strength was 240 MPa, the flexural strength was 175 MPa, and the fiber length was 25 mm, which was consistent with the fiber length of the LFT-G particles. resulting in a loss of fiber length.
Embodiment 2
[0036] A moldable high-performance thermoplastic composite material with a single fiber length distribution, calculated in parts by weight, comprises the following components: 50 parts of glass fiber filaments; and 50 parts of resin.
[0037] In this embodiment, 2400tex glass fiber filaments are used, polypropylene is used as resin, melt index is 25g / 10min, glass fiber mass fraction is 50±5wt%, LFT-G particle length is 15mm, and fully heated at 230°C to make 4mm The LFT-G plate is heated and baked at 230°C, and then molded to obtain a product.
[0038] The tensile strength, flexural strength test and fiber length characterization of the prepared parts were carried out. The tensile strength was 230 MPa, the flexural strength was 160 MPa, and the fiber length was 15 mm, which was consistent with the fiber length of the LFT-G particles. resulting in a loss of fiber length.
Embodiment 3
[0040] A moldable high-performance thermoplastic composite material with a single fiber length distribution, calculated in parts by weight, comprises the following components: 50 parts of glass fiber filaments; and 50 parts of resin.
[0041] This embodiment uses 2400tex glass fiber filament, the resin is polypropylene, the melt index is 25g / 10min, the glass fiber mass fraction is 50±5wt%, the length of LFT-G particles is 10mm and 20mm, the proportion is 50%, and the temperature is 230°C. After being fully heated, a 4mm LFT-G plate is made, and the plate is heated and baked at 230° C., and then molded to obtain a product.
[0042] The tensile strength, flexural strength test and fiber length characterization of the prepared parts were carried out. The tensile strength was 215 MPa and the flexural strength was 165 MPa. There were two fiber lengths of 10 mm and 20 mm, which were consistent with the fiber lengths of LFT-G particles. The processing did not result in a loss of fibe...
