The main purpose of preparing sisal fiber reinforced PLA composite is to improve the mechanical properties of PLA and reduce the production cost.
At the same time, in this paper, USF, ASF and sf-g-la fibers were respectively mixed with PLA matrix for smelting and blending, and then PLA/USF, PLA/ASF and PLA/ sf-g-la composites were prepared by molding on a flat vulcan press, and compared with pure PLA, the thermal properties, crystallization properties and mechanical properties of the composites were studied.
The content of initiator is the most important factor affecting the graft rate of sisal fiber.
However, due to many factors affecting the properties of fibers and fiber-reinforced polymer matrix composites, this paper fails to cover and consider each of them.

There are many factors affecting the fire safety of entertainment places, which can be divided into four categories: building property, fire control facilities, fire safety management and personnel factors[3,4].
The factors of building property mainly include the fire resistance rating, fire zoning, and the evacuation passageway design, etc.
Fire prevention design is carried on in the design stage, the main influencing factors of fire risk are building property and fire control facilities.

In micro/nano meter scale, the surface effect may have a significant impact on the mechanical properties of the materials and then affects the life, duration, and reliability of the product.
To find out solutions for these problems, it's quite important to find out the mechanical properties of the material under nano-meter scale.
In this study, we utilize spring components to represents the elastic mechanical properties, as shown in Figure 5(a).
Both of these factors result in the high indention hardness.

This is a relevant situation related to economic factors, energy consumption and productivity involved in the manufacture of composites [1].
In spite of the technological attractiveness, none of these methods guarantee the mechanical properties of the composite due to the relatively long time (6 min to one hour) of sintering operation.
It was found that temperature and pressure are not the only factors to ensure the initial quality of the precursor diamond powder, the sintering time is also important.
The actual difference of about 50% indicates that other factors in the composite do not allow the Rule of Mixture [10] to be used.

In the present work special features of the structure, phase composition and properties of such high-speed steels designed for cast tool are studied.
Specimens for mechanical tests, metallographic examination, and XRD analysis were prepared from the above-mentioned ingots.
Such cast fine-grained structure of a ferritic matrix is due to several factors.
All these benefit in improved mechanical properties, first of all in impact toughness of as-cast high-speed steels.

In order to prolong the fatigue life of the machine tools, this study investigates the effects of the lubricants on the tribology properties under the extreme pressure for the induction-treated linear guides.
The mechanisms of the lubricants on the tribology properties for the mechanical equipment in the continuous operations [1]: the lubrication functions of the frictional contact points are mainly provided by the base oil and lubricating additives in the grease.
Masuko et al. [7] used a micro-friction testing machine to investigate the wear characteristics under boundary lubrication conditions, and found that the friction coefficient under lubrication conditions was affected by a number of experimental factors.
Therefore, this experiment used the variations of friction coefficient and the analysis of wear depth and worn surface to investigate the effects of the lubricants on the tribology properties of the induction-treated linear guides.

In this paper, the effects of hydrogen content on structure, mechanical properties, surface wettability and haemocompatibility were discussed. 1 Introduce Amorphous hydrogenated carbon (a-C:H) thin films have assumed a great interest because of their possible application in mechanics, optics and electronics [1-3].
Recently, a nano-indentation technique has been used to investigate mechanical properties of thin films.
The haemocompatibility of the a-C:H films is influenced by θw and γs p /γs d , not by the absolute γs p or γs d because the materials haemocompatibility is affected by many factors such as the ratio of sp 3 to sp 2 , electrical properties and composition etc.
The platelet adhesion behavior better is only one indication of anti-thrombogenicity, the other aspects of anti-thrombogenicity, such as coagulation factors, protein adsorption, should be done later on.

In addition, the mechanical and physical properties of MMCs can be tailor made to meet specific design criteria.
Interfacial thermal resistance is one of the most important parameters since it is related to the solidification time and mechanical properties of the casting.
Interfacial thermal resistance depends on a number of factors including the thermo physical properties of the melt and mould and the formation of air gap between the casting and the mould.
This results in better mechanical properties.
Interfacial thermal resistance is one of the most important properties since it controls the solidification time and mechanical properties.
