Railroad Composite Brake Block For Train And Wagon Refer To Standard GB/T 9439-1988

Product Name: Composite Brake Block

Standard GB / T 9439-1988 Plain Surface Composite Railway Brake Blocks

Brief introduction:

Our cast iron brake block enjoys many advantages including hardness, impact strength and so on. It consists of two parts, the cast iron and the steel support. Both the surface and core of the cast iron have the hardness within the range of 197< HB< 255.

When facing subsequent impacts to the brake block or brake shoe, the steel support must remain intact and attached to the iron places. The connection bridge may possibly become detached but should not show any soundness defects. Separated from the brake shoe, the support must be able to withstand the bend test with cracking or breaking.


The brake shoe are located on the wheel tread.

when braking, two pieces of brake block clamp the wheel to make it stop.

Composite material,high friction composite brake shoe,

low friction composite brake shoe


--Composite friction material bearing high energy braking;

--High coefficient of friction and stability,

--small heat fade for coefficient of friction,

--Temperature insensitiveness,

--Develop according to the samples or drawings


Material Character:

  1. The materials of composite brake block consist of 3 main substances including reinforcing fiber, organic/inorganic filler and resin bound.
  2. It has a high level of uniformity.
  3. It can be separated from the backing plate.
  4. It contains no asbestos, lead, zinc or other mixtures.
  5. It also contains no toxic materials.
  6. The hardness of the material is lower than the wheel's.
  7. It causes no strong smell in friction.

Backing plate:

Backing plate for a trains' composite brake block must meet the following criteria. Firstly, it is made of ST-41 steel plate, and is constructed to transmit the braking force to the composite material. Secondly, there should be a binding structure between the composite material and backing plate, thus forming into a integrated unit and ensuring sufficient bending strength and stiffness.

Test procedure:

  1. Vernier caliper or other methods are used to test the dimension of the brake block.
  2. Laboratory test

Specific gravity test: standard ASTM D 792 or equivalent method
Coefficient of friction test: Standard ASTM D 1894 or equivalent method
Hardness test: standard ASTM D 785 or equivalent method
Shear resistance test: standard ASTM D 732 or equivalent method
Press test: Standard ASTM D 695 or equivalent method
Bending test: Standard ASTM D 790 or equivalent method
Thermal properties test: standard ASTM D 177 or equivalent method


  1. Excessive wear won't be caused on the surface of the wheel and the composite brake block.
  2. The composite brake block will not cause the wheel porous or cracked.
  3. It won't stick at the wheel during braking therefore won't cause uneven wheel surface.
  4. It won't cause wheel slipping during full braking in wet conditions.


  1. Composite friction material bearing high energy braking;
  2. High coefficient of friction and stability,
  3. Small heat fade for coefficient of friction,
  4. Temperature insensitiveness,


Produce a stench when tight.


Our composite brake block is an ideal replacement of the metallic (gray cast iron) brake block. Composite brake block features motion to the wheel and well fitness between the brake block and brake block shoe (brake holder).
