Embodiment 1

[0034] A cuboid-shaped fiber-reinforced rubber vibration isolator, the vibration isolator is composed of rubber layers 1 and fiber layers 2 interlaced and laminated and vulcanized and bonded to form an integral body. The fiber layer 2 is made of resorcinol formaldehyde (RFL) resin-treated fiberglass fabric, the rubber of the rubber layer 1 is natural rubber (see Figure 1 ~ Figure 3 ).

Embodiment 2

[0036] A cuboid fiber-reinforced rubber vibration isolator, the vibration isolator is composed of a rubber layer 1 and a fiber-reinforced rubber layer 3 interlaced and laminated in the thickness direction and bonded together by vulcanization. The fiber-reinforced rubber layer It is a composite material layer formed by co-vulcanizing the rubber layers 31, 33 on the upper and lower surfaces and the fiber reinforced material 32 between the upper and lower rubber layers. The fiber reinforced material 32 is made of resorcinol formaldehyde (RFL ) resin-treated fiberglass fabric, the rubber of the rubber layer 1 is natural rubber (see Figure 4 ~ Figure 5 ).

[0037] As a transformation of Embodiment 1 and Embodiment 2 of the present invention, the fiber material of the fiber reinforced material of the fiber layer or fiber reinforced rubber layer can also be replaced by high-strength glass fiber, carbon fiber, aramid fiber, basalt fiber Or one or several kinds of polyester fibers ar...

Embodiment 3

[0042] A manufacturing method of the fiber-reinforced rubber vibration isolator described in the second embodiment, the method is to overlap the fiber-reinforced rubber layer 3 and the rubber layer 1 in the thickness direction, and form a whole after being vulcanized and bonded. Include the following main steps:

[0043] A. Surface treatment: surface treatment of fiber materials with resorcinol formaldehyde (RFL) resin to prepare fiber reinforced materials;

[0044] B, preparation of fiber-reinforced rubber layer: the above-mentioned surface-treated fiber-reinforced material is put between the rubber layers of the upper and lower layers, and the composite of fiber and rubber is completed by co-vulcanization to obtain a fiber-reinforced rubber layer (see Figure 5 );

[0045] C. Lamination: According to the lay-up design requirements, the fiber-reinforced rubber layer and the rubber layer are laminated separately until the total thickness of the fiber-reinforced rubber layer a...

Abstract

A FRP reinforced rubber vibration isolator and manufacturing method thereof, relate to a vibration isolator and a manufacturing method thereof. The vibration isolator is formed by a rubber layer and a stiffening layer which are staggeredly superposed, vulcanized and bonded in the thickness direction, wherein the stiffening layer is a fiber layer formed by fiber reinforced material, or a fiber reinforced rubber layer formed by rubber layers on the upper and lower surfaces and fiber reinforced material arranged therebetween through co-vulcanization; the fiber reinforced material for forming thefiber layer or the fiber reinforced rubber layer is the fiber material after RFL resin surface treatment before vulcanization with rubber or combination with rubber. The manufacturing method comprises surface treatment, preparation of the fiber reinforced rubber layer, superposition, vulcanization molding. The fiber reinforced vibration isolator has a certain bearing capacity and high energy damping capacity, good durability and corrosion resistance, and high designability, and has simple and applicable manufacturing method.

Description

Technical field: [0001] The invention relates to a vibration isolator and a manufacturing method thereof, in particular to a fiber reinforced rubber vibration isolator and a manufacturing method thereof. Background technique: [0002] Vibration is a common problem in daily life and engineering technology. It will affect the human body, vehicles, mechanical equipment or structural components to varying degrees. In order to slow down the amplitude of vibration and avoid the harm caused by vibration, usually in the vibration A vibration isolator is added between the source and the vibrating body, while cutting off the transmission of vibration, it can effectively suppress vibration through energy consumption and prevent resonance phenomenon. Existing types of vibration isolators include: anti-vibration rubber, metal spring, air spring, sponge rubber, felt and cork, and cylindrical oil damper, etc. Among these vibration isolators, metal spring and air spring have strong bearing ...
