Besides that it also has excellent properties for sound absorption, and nanocellulose as a derivative of cellulose material has excellent physical, mechanical, chemical and thermal properties [1,2] Polymer-based materials can be derived from natural or petrochemical sources.
However, the synthetic polymer material in its application still causes a number of constraints, for example the properties of resistance to biodegradation, chemical stability, destruction takes a very long time.
The addition of nanocellulose affects the acoustic properties of the material.
Density was an important factor to determine acoustic efficiency in the same composite type.

Introduction Duplex stainless steel (DSS) has been widely used in many fields such as petroleum refining, paper manufacturing and ocean industries due to its excellent combination of high mechanical properties, good corrosion resistance under critical working conditions [1-4].
Compared with 2205 commercial DSS, the deformation difference of two phases for 2101 DSS are considerably affected with more Mn and N addition.
Therefore, in order to improve hot working property, it is of great important to research hot deformation behavior with different deformation temperature and strain rate.

However, no standard has yet been established to evaluate the replacement of automobile parts, and such a standard must account for mechanical properties of the material under tensile and flexural loadings.
Recently, Lee et al. [12] investigated mechanical properties of center-pillar reinforcements made of CFRP–steel hybrid composites by performing tensile and bending tests.
Subsequently, via numerical analysis and microstructure observation, they confirmed problems associated with mechanical properties of side structures.
Current standards of collision tests solely depend on the trends in mechanical properties observed during tensile and bending tests.

The tribological properties of the surface hardened layer and untreated substrate were investigated using a block-on-ring tribometer sliding against GCr15 steel under unlubricated condition.
Introduction Surface properties are often a decisive factor affecting the performance and service life of a workpiece, and there are various kinds of surface treatment techniques for structural materials.
The geometric characteristics of melted and heat affected zones were studied as a function of working parameters.
When the two previously unworn material surfaces are first brought into contact, mechanical, thermal, chemical and microstructure changes begin to occur in and adjacent to the contact interface.
Martensite formed in the surface hardened layer has the properties of high hardness, fine grain size inherited from the substrate and severe dislocation.

In order to study the effects caused by geometrical and material factors, such as aspect ratio, volume fraction, interface stiffness and thickness on the composites mechanical properties, Tserpes and Chanteli [5] used a homogenized representative volume element (RVE).
They also concluded that just low values of the aspect ratio (aspect ratio of 20 and below that) affect these properties, while the interface effect is significant in lateral directions.

In order to improve the human engineering properties for the racing wheelchair, using the CATIA Human Engineering Analysis module, this paper established the human body 3-D model, analyzed the eligibility of the hold and the extend for the racing wheelchair, analyzed and evaluated the comfort of three typical sports postures of human body.
The Establishment of the Human Body Model The human body model is established based on human body parameters, it is an effective tool which describes morphological characteristics and mechanical properties of human body, it is also an indispensable auxiliary tool that can be used to research, analyze, evaluate, and test the man-machine system.
The reasonable human movement postures could reach the requirement of the human force, the unreasonable ones could cause fatigue, evoke occupational diseases and affect the match result during to energy over-consumption.
In this paper, the upper limb of the 3-D human body for the racing wheelchair model had three sports postures, which contained: initial posture when driving the wheelchair, one of Middle postures when driving the wheelchair, and open posture of both arms when leaving the wheelchair, these three postures we edited are shown in Fig.6. 1) Initial posture 2) Middle posture 3) Open posture Fig.6 Three sports posture edit Because the comfort is a subjective feeling, that is the comprehensive feeling of pain, fatigue, and force and so on, which is influenced by various physiological factors such as the joint angle, muscle tissue pressure and blood circulation block.

The improved strength and ductility is a result of a spheroidizing Mg treatment of a base iron, which requires a critical residual Mg content (0.03-0.06%Mgres), usually accompanied by rare earth elements (REE), depending on the charge materials, base iron chemistry, castings characteristics, and the required structure and properties.
Their unique properties have made them crucial to a number of emerging and growing technologies, increasing their demand and strategic importance, and, consequently, the price.
The cumulative influence of the chemical composition of the Mg-treated irons as they affect pearlite content (factor Px, Equation 4) and anti-nodularising effect (factor K, Equation 5), according to Thielman’s factors [8] are included in Table 1.
Cooling rate (greater distance from the apex, lower cooling rate), REE contribution of Mg-treatment (low and high REE level) and post-nodulizing treatment (un-inoculated and inoculated irons) were seen to be the most important factors on carbide sensitivity and graphite phase quantity and characteristics (Figures 2-4).
Higher SSF, higher graphite phase quality, with benefits to the mechanical properties, especially for ductility.
