Mostly the influence on mechanical properties was observed.
As the relation between mechanical property and process parameters is difficult to establish, attempt has been made to derive the empirical model between the processing parameters and mechanical properties using statistical methods [8].
The foregoing discussions reveal that FDM processed parts exhibit anisotropy of mechanical properties.
Properties are sensitive to the processing parameters because parameters affect mesostructure and fiber-to-fiber bond strength.
Operator gets the part with comparable or higher mechanical properties.

Introduction
The usefulness of steel Mn-Al in welded constructions requires the assessment of factors connected with weldability of those steels, and in particular, the changes of structure occurring in welded joint under the influence of heat of welding, determining the resistance to cracking and conditions of welding and bonding which meets the required mechanical and useable properties
[1, 2, 3].
Phase secretion of Mn8Al5 is supported by formulation of ferrite in the shape of needles arranged at an angle of 60 and 120° and is the reason why mechanical properties of welded joints deteriorate [4].
After introduction of chosen types of FeMnAl steel to production, it will be necessary to prepare binding materials with chemical composition which would allow to achieve high mechanical properties.
After introduction of chosen types of Mn-Al steel to production, it will be necessary to develop binding materials with chemical composition which would allow for the achievement good mechanical properties.

It was founded that the microstructure of sintered alloys very strong correlated with the type of initial powders that, nevertheless, not affects on mechanical properties of sintered alloys.
This fact as the strain hardening also can affect on the tribological properties of Al-40Sn alloy.
To evaluate the effectiveness of mentioned above factors on the behavior of the alloy under the dry friction, the power their influence need to separate.
Further thinning of the aluminum interlayers is almost no affect the character of Sn distribution on the friction surface and therefore does not change the tribological properties of surface third body.

Polypropylene (PP) is commonly used to reinforce natural fibres due to its superior physical, mechanical, and thermal properties.
Matrix polypropylene (PP) is known to possess superior and fascinating physical, mechanical and thermal properties.
The challenge mainly comes from fibre treatment in ramie fabric, which affects mechanical characteristics.
This was done to prevent any negative effects that alkaline residue could have on the composite material's mechanical properties.
Shear strength in composite is one of important factors affecting its application.

Through the analysis of factors affecting the compaction properties of materials,self-vibration phenomenon and resonance phenomenon,theoretical study on the effect of shear strength of the material vibration, the comparative experiments were conducted by heavy compaction instrument and vibration compaction instrument,accommodate compaction property of graded crushed aggregate,the test methods were obtained,also the test parameters were determined, and verified by experiment.
0 Introduction
Graded crushed aggregate is composed of different sizes of gravel, and meeting certain grading requirements,which can achieve high strength and stability.
Fine graded gravel layer has higher stiffness, which can provide good load distribution properties and high shear strength to reduce vehicle deformation under the action of the rut.
Factors affecting the compaction effect The main factors influencing the effect of graded gravel compaction have two aspects: one is the internal factor including the material physical properties, gradation composition, layer thickness and water content, the other is the external factor.
According to the theory of resonance, the best compaction effect may be produced in the natural frequency range of mechanical and material system, when the resonance occurs, spring elastic effect may occur which would increase the compactness of the materials. 2.2 Influence of vibration on the shear strength of the materials In the process of vibration compaction, the shearing strength of the material was mainly affected by three factors: namely the cohesive force between particles, the sliding friction and interlocking friction, as shown in Eq. (1).
(2) Test Material The physical properties and graded composition of materials testing shown in Table 1 and Table 2.

Comparison between the different joints was carried out on the basis of the mechanical properties.
A central composite factorial scheme with three centred faces factors and α = 1 with central point replied four times.
Process parameters were classified into two classes: variables and fixed factors.
A constant value was set for the fixed factors and ranging values for the variable ones. 2.2 Mechanical characterization Static tensile tests were performed on samples consisting of three valid specimens from each weld.
