Along with the development of the high polymer and the needs of the production of the modern industry, engineering plastic as a new type of gear materials have been widely used.
Owing to the composite materials large deformation, the maximum and central oil pressure of the meshing point of composite gear pair engagement is obviously higher than steel-steel gear engagement.

Thus, many researchers are focusing their interest on producing materials suitable for large EM wave absorption.
The absorption of EM waves occurs in magnetic materials due to their magnetic losses[1].

Fitting models to composite materials.

In this paper, a ring shaped numerical specimen is used to studying the failure process in brittle materials.
In this paper, a hollow disc shape specimen with a double center crack subjected to diametral compressive loading is proposed to study the fracture process of brittle materials like rock.

Often it has been found a mixture of manufacturing methods and materials is required. 3D printing is more suited for complex shapes as 3D printing allows internal and external shapes to be made in one manufacturing step, with much shorter set up times, however materials are limited to the 3D printing machine type, and the surface finish is rougher compared to CNC machining.
Wood was not used as the materials produces dust particles that for the machining of such large surface with the required surface finish would have contravened aspects of the mandatory Australian health and safety regulations.
Case (iii): Manufacture using a combination of 3D printing and CNC machining This is another example where shape or configuration dictated the choice of materials and machining methods.

Effect Of Different Sintering Temperature On The Performance Of Mullite-Corundum Refractory Materials LI Ping1,2, GU Xing Yong1,2,a, LUO Ting1,2and Chen Yun Xia1,2 1Jingdezhen Ceramic Institute, Jingdezhen, Jiangxi, 333403, China 2Jiangxi Provincial Key laboratory of advanced ceramic materials, Jingdezhen, Jiangxi, 333403,China aguxing-y@163.com Keywords: Sintering temperature; Mullite whisker; Formation in-situ; Refractory materials Abstract.
The mullite-corundum refractory materials with well-dispersed needle-like mullite formed in-situ were prepared.
Secondly, calcined bauxite and Suzhou kaolin, the raw materials of the sintered materials, were weighed, wet grinded, dried and then sieved by 120 meshes.
Finally, the grinded and sieved raw materials of the sintered material and the granulated precursors of mullite whisker were weighed respectively and mixed uniformly according to the designed mass ratio of 7:3.
