Embodiment 1

[0036] A basalt fiber cloth composite automobile leaf spring, comprising the following compositions in weight percentage: 34% epoxy resin; 66% basalt fiber cloth.

[0037] Epoxy resins are polyurethane modified.

[0038] Basalt fiber cloth is plain weave reinforced basalt fiber cloth.

[0039] A preparation method of a basalt fiber cloth composite automobile leaf spring, comprising the following steps:

[0040] Step a, preparation of prepreg: unwind the roll of basalt fiber cloth and impregnate epoxy resin in the glue tank, then send the strip blank into the drying tunnel that can be baked continuously to remove the organic solvent in the strip blank, and perform preliminary prepreg Pre-polymerization, the gray cloth is not sticky after drying, and then it goes out of the drying tunnel, winds up, and is ready for use after passing the inspection.

[0041] Step b, material cutting: Cut the qualified prepreg gray cloth into the required size, and put it neatly for later use. ...

Abstract

The invention relates to the field of lightweight of automobiles, and relates to an elastic plate, in particular to a basalt fiber fabric composite automobile plate spring and a preparation method thereof. The basalt fiber fabric composite automobile plate spring consists of the following components in percentages by weight: 30-40% of polyurethane modified epoxy resin and 60-70% of a basalt fiberfabric. The provided basalt fiber fabric elastic composite automobile plate spring has the characteristics of high mechanical strength, no cracking, wide used temperature range, flame retardance, no smoke, ultraviolet resistance, weather resistance, chemical corrosion resistance and good moisture resistance, and meanwhile has the advantages of reasonable structure and low density. Compared with atraditional steel automobile plate spring, the basalt fiber fabric composite automobile plate spring has the advantages that the weight can be reduced by 60-70%, and the basalt fiber fabric compositeautomobile plate spring is suitable for a lightweight arc-shaped automotive composite plate spring.

Description

technical field [0001] The invention relates to the field of lightweight automobiles, and relates to an elastic plate, in particular to a basalt fiber cloth composite automobile leaf spring and a preparation method thereof. Background technique [0002] Basalt fiber is a non-metallic inorganic material. It is a new material for energy saving and environmental protection in the 21st century. It is also a pollution-free "green industrial material". It is drawn from natural basalt ore through high-temperature melting. At present, it has been gradually applied in my country's aerospace, automobile and ship, petrochemical, weaponry, civil engineering transportation, energy saving and environmental protection, fire protection clothing, sports equipment and other fields. [0003] Traditional automotive elastic leaf springs are generally made of metal materials. There are roughly two types of current composite material leaf spring processes: one is the winding forming process. By c...
