Study on Carbon Fiber Composite Materials in Sports Equipment Jiangzhi Zhang Shandong Sport University, Jinan, Shandong, China 250102 Keywords: Carbon Fiber Composite Materials; Sports Equipment; Use Abstract.
Compared to these materials, fiber-reinforced composite materials have obvious advantages in the following areas.
Composite material during use does not emit harmful gases, and thermoplastic composite materials can be recovered using the same time, the prices of raw materials for production of composite materials is generally low, low processing costs, conducive to the popularity of the product and promotion.
Application Examples of Carbon Fiber Composite Materials in Sports Equipment Golf clubs.

The contacting shoulder and pin surface make the workpiece materials to soften into the plastic state, then the materials flow around the tool pin from the front to rear, where it consolidates and forges under the confining pressure [3].
The depth of tool penetrating into workpiece was constant, the vertical force acting on the material decreased with the materials became softer.
Comparing the three materials, the vickers hardness of TC4 was highest, and the vickers hardness of T2 was higher than LY12.

The secondary raw materials restarted in the production process can consist of at least three qualitatively different categories of materials: - with the same characteristics as the original materials - with characteristics of new materials, replacing the traditional ones in the same applications from which they originated - with characteristics of new materials, replacing traditional ones in applications other than those from which they originated The first category includes those materials which, after having been separated in the treatment phase, can be added to the virgin material at any stage of its transformation process and are no longer distinguishable from it.

Study on mine materials with exploring for future development direction of resources crisis on mines YuXue Bao (Liaoning Geology Engineering Vocational College, Dandong 118008, china) Keywords: mine materials, resources crisis, mining enterprise, development direction Abstract :The resources crisis mines is a necessary stage of mining enterprise development, the mine materials with exploring for future development direction of resources crisis on mines concerning the rise and fall of the country, The scientific analysis and beneficial exploration for future development direction of the resources crisis mines, which can provide reference for the future development of resources crisis mines. 1.
According to the international market price of mineral resources and the mine materials [3], Mining enterprises scientifically formulated with industrial index of the enterprise, dynamic production quality control of mine.
Second, According to the rules of market economy, mining enterprises control cost of the mine production and the mine materials.
Chinese should formulate relevant policies to encourage enterprises to speed up development, to looking for all kinds of mineral resources substitute and ease the resource crisis pressure, because of the great amount metal and the mine materials consumption [3]. 4.6 Go out of the country with its own advantages, explore the surrounding countries, mineral resources and the mine materials market In response to the grim situation of mineral resources in China, on one hand, we should strive to develop and make use of domestic resources, on the other hand also to seize the opportunity, make use of their own advantages to develop the international market, to explore the mine materials and mineral resources in the countries and regions rich.
