However, in both the spline function and the Mean & Difference method, only the tensile properties of the given membrane materials could be fit very well.
There are a lot of factors affecting the deformation mechanism of the materials when loading under uni- or bi-axial tensile condition.
The factors are as follows: the structure of the woven basic fabric, the tensile properties of the yarns and the coating material, the thickness of the coating, the interaction (such as slipping and crushing) between the basic fabric and the coating material, the crimp interchange of the warp and the fill yarns[1, 12], etc.
The method could provide a rough understanding of the tensile properties of the membrane materials in the applications.
By this kind of method, it could be expected for the design of the tensile properties of the woven membrane materials.

The paper deals mainly with soft thermal insulation mats and the factors that affect the thermal insulation properties of the insulating material in its manufacture and subsequent incorporation into the structure.
Fig. 1 Dependence thermal conductivity on density Fig. 2 Dependence tensile strength on density From the viewpoint of mechanical properties a weak dependence on density was demonstrated for compressive strength; in the case of stress at 10 % of deformation the correlation could not be prooved.
In the case of the acoustic properties no dependence on density was proved as well, but in the case of dynamic stiffness depends acoustic properties on type and thickness of fibers (thickness was variable) and it is not possible to receive simple dependence on density with variable other properties.
A weak dependence of tensile strength perpendicular to the plane of the plate on density was reported in terms of mechanical properties; by stress at 10 % deformation dependence on density was not found out.
Dependence between acoustic properties and density wasn’t found out because thickness of samples was variable.

The result of second stage of the study showed no meaningful difference between mechanical and physical properties of composite boards containing 10 percent of walnut and almond shell with reference one (board A).
Analyze of variance (ANOVA) was used to test for significant difference between factors and levels.
The result indicated that increasing press pressure and press time adversely affect the properties of the boards. 2.
The ratio of wood particles to walnut/almond shells, press time, and press pressure negatively affected the physical and mechanical properties of the panels while the increasing of press temperature improved the modulus of elasticity, modulus of rupture and internal bond strength. 5.
It was revealed that both physical and mechanical properties of the panels containing 10 percent walnut/almond shells regardless of shell mesh size was better than those produced from neat wood particles.6.
