Problems solved by technology

It has a very good effect on the shock absorption of vehicles, but the shortcomings are mainly due to the heavy weight, so the impact force on the vehicle is relatively large during the shock absorption process, and the load capacity of the vehicle is also reduced.
Simultaneously, because it does not have the forerunner of damage, the traffic accident of car crash very easily takes place; In addition, production cost is higher

Embodiment 1

[0026] Such as figure 1 , 2 As shown, the manufacturing method of the FRP composite material leaf spring of the present invention, it first impregnates the roving or gray cloth made of glass fiber material, and then lays it in the epoxy resin matrix in a multi-layer superimposed manner, Then place it in a mold and press it into a rectangular leaf spring; the lower surface of the leaf spring is a paraboloid that is thick in the middle and gradually thins toward the two ends along the length direction; the thickness at both ends is smaller than the maximum thickness in the middle.

[0027] The roving or gray cloth made of the multi-layer glass fiber material can be superimposed and laid in the following manner:

[0028] Based on the central plane N of the thickness of the leaf spring, the fiber material layer near the upper and lower surfaces of the leaf spring is an outer layer 1 that extends continuously to the entire length direction of the leaf spring; the fiber material la...

Embodiment 2

[0030] Such as figure 1 , 3 As shown, the manufacturing method of the FRP composite material leaf spring of the present invention, it first impregnates the roving or gray cloth made of glass fiber material, and then lays it in the epoxy resin matrix in a multi-layer superimposed manner, Then place it in a mold and press it into a rectangular leaf spring; the lower surface of the leaf spring is a paraboloid that is thick in the middle and gradually thins toward both ends along the length direction; the thickness of both ends is smaller than the maximum thickness in the middle.

[0031] The roving or gray cloth made of the multi-layer glass fiber material can be superimposed and laid in the following manner:

[0032] Based on the central plane N of the thickness of the leaf spring, the fiber material layer near the upper and lower surfaces of the leaf spring is an outer layer 1 that extends continuously to the entire length direction of the leaf spring; the fiber material layer...

Embodiment 3

[0034] Such as Figure 4 Shown, in embodiment 1 or 2, described outer layer 1 also can be laid like this:

[0035] The outer layer 1 away from the surface of the leaf spring is disconnected near the end of the leaf spring, and the truncation point 4 moves successively from the upper layer front of the outer layer 1 to the lower layer rear of the outer layer 1; the truncated outer layer 1 can It is a superposition of single layer, double layer or multiple layers.

[0036] Such as Figure 5 As shown, the outer layer 1 can also be laid in the following way: the outer layer 1 is laid with a stepped layer 5 passing through the entire truncation point 4 through the position of the truncation point 4 .

Abstract

The present invention discloses production process of plate spring of composite GRP material. After several fiber material layers are spread inside synthetic resin base, the resin base is pressed inside mold to form plate spring of required shape. The fiber material may be roving fabric or grey cloth. The composite GRP material of the present invention has the advantages of light weight, great elastic strain and high specific strain energy, and the plate spring is used in vehicle to improve vehicle performance.

Description

technical field [0001] The invention relates to the field of leaf springs, in particular to a method for manufacturing a glass-steel composite material leaf spring. Background technique [0002] Leaf springs are mostly used for shock absorption of vehicle chassis, and the materials used in current leaf springs are made of spring steel. It has a very good effect on the shock absorption of the vehicle, but the main disadvantage is that it has a large dead weight, so the impact force on the vehicle is relatively large during the shock absorption process, and the load capacity of the vehicle is also reduced. Simultaneously, because it does not have the foreshadowing of damage, the traffic accident of car crash very easily takes place; In addition, production cost is higher again. Contents of the invention [0003] The object of the present invention is to provide a method for manufacturing a glass fiber reinforced plastic composite material leaf spring which can reduce its ow...
