The mechanical properties of Ph.
The MPF was 10.1 KN, The internal structures of bamboo determined their mechanical properties, so the anatomy of bamboo could also affect the mechanical properties of bamboo.
Correlation of soil NPK and the mechanical properties of bamboo The correlation analysis between soil nutrients and mechanical showed the relation on between soil nutrient and mechanical properties of bamboo wood were not correlated significantly.
There was no significant difference of mechanical properties on soil NPK.
Test methods of bamboo physical and mechanical properties.

Inspite of the well-studied thermal and mechanical properties, there are few investigations focusing on the variations of the electrical properties and CTEs of the epoxies after the gamma-ray exposure.
Electrical properties, CTE and mechanical properties were studied for a comprehensive evaluation of the epoxy material, accompanied by the analysis of the chemical compositions, Tg and density.
Thermal, Physical and Mechanical Properties.
The thermal, physical and mechanical properties of the intact epoxies and the irradiated epoxies are listed in Table 1.

Research of the Transient Temperature Field and Friction Properties on Disc Brakes Zhang Jiana Xia Changgaob School of Automobile and Traffic Engineering, Jiangsu University, Zhenjiang, Jiangsu, China ajzhangyangtze@126.com,bxiacg@ujs.edu.cn Keywords: Disc brake; Transient temperature field; Friction properties (key words) Abstract.
(Abstract) Introduction The braking performance of the automotive is one of the most important factors that affected the traffic safety and the brake is the key components related to the running safety of the automotive.
The relationship between friction factor and temperature Many factors affect the friction factor, the temperature of friction surface is the most significant.
The normal pressure and relative sliding velocity between disc and pad affect the friction factor by affecting the temperature.

Mechanical Properties and Fatigue Resistance of 3D Printed Inconel 718 in Comparison with Conventional Manufacture Ivo Černý1,a, Jan Kec1,b, Tomáš Vlasák1,c, Luboš Remar1,d, Miroslav Jersák1,e and Miroslav Zetek2,f 1SVÚM a.s., Tovární 2053, 25088 Čelákovice, Czech Republic 2University of West Bohemia, Faculty of Mechanical Engineering, Univerzitní 8, 30614 Plzeň 3, Czech Republic aIvo.Cerny@seznam.cz, bkec@svum.cz, cvlasak@svum.cz, dremar@svum.cz, ejersak@svum.cz, fmzetek@kto.zcu.cz Keywords: Direct Metal Laser Sintering, Inconel 718 alloy, microstructure, mechanical properties, fatigue durability, creep.
The paper contains results of the first stage of experimental programme aimed at an evaluation of microstructure, mechanical properties, fatigue durability and creep of the first batch of Inconel 718 samples manufactured using the 3D printing technology, Direct Metal Laser-Sintering (DMLS).
It is a net-shape process, producing parts with high accuracy and detail resolution, good surface quality and usually good or even excellent mechanical properties, at least according to technical manuals of manufacturers of DMLS facilities.
One of the most important factors affecting the printed material quality is input powder.
Creep resistance looks to be the weakest point of this printed material and steps to improve the properties will have to be undertaken.

The importance of factors affecting the growth of plants from large to small is: fly ash, the ratio of loess and peat soil, sludge, rice husk, cement.
Therefore, the uncertain factors affecting the substrate inspection index are only sludge, fly ash, cement, rice husk, and the ratio of loess and peat soil.
Among them, the highest PH value of cement is the biggest factor affecting the PH value of the substrate.
The importance of factors affecting the growth of plants from large to small are: fly ash, the ratio of loess and peat soil, sludge, rice husk, cement
(3) Based on the field test, the growth condition and mechanical properties of vegetation were studied.

Keywords: SiNO fiber; precursor infiltration and pyrolysis; wave-transparent composites; pyrolysis temperature; mechanical properties; dielectric properties Abstract.
The effect of pyrolysis temperature on the densification behavior, microstructures, mechanical properties and dielectric properties of the composites was investigated.
Hence, it is the two contrary factors above that determine the final mechanical property of composites [13].
Generally, the mechanical properties of the composites are determined by the combination of retained fiber strength, matrix properties and the behavior of the fibre/matrix interface.

And hot pressing was adopted when the composite was manufactured and some mechanical properties such as tensile strength, bending strength and impact energy absorption were tested and analyzed.
Test mechanical properties of samples made by universal sample maker.
As we could see from Table 1, what affected the mechanic properties most was concentration of peanut hull.
In order to optimize the exact concentration of peanut hull which made the best mechanic properties, a single factor analysis was adopted.
Other factors were fixed.

The Mechanism of Formation of Casting Skin in CG Iron and its Effect on Tensile Properties Sarum Boonmee a and Doru M.
Introduction It has been reported that iron with as-cast surface has lower mechanical properties than fully machined test bars [1,2,3,4] because of the casting skin effect.
This effect can be more severe for fatigue properties.
