Plasma discharges have been extensively used as a means to modify the surface characteristics and to improve the blood compatibility of polymeric materials.
The blood compatibility of common polymeric materials such as PET and PU can be improved to some extent by radio frequency glow discharge[3,4,5] .

There are many factors responsible for structural collapse in developing nations; some of these include corruption, insufficient supervision, incompetence, greed, poor planning, lack of compliance to building codes, poor quality of materials, and limited financial resources [7].
It takes into cognizance uncertainties in both structural and material parameters.
According to [18, 19], the use of poor quality construction materials is among the major causes of building collapse in Nigeria.

Introduction Smart Textiles describes a huge field of functionalized texiles and materials.
Commonly, smart textiles are defined as intelligent materials and systems that are capable to sense and respond to their surrounding environment in a predictable and useful manner [1].
Sensors are defined as detectors that are capable of receiving physical values or materials and process characteristics and transforming them into binary, one- or multidimensional electrical measurement signals.
Depending on these modular connections, influences through materials, combination of materials or additive compounds, the way of producing fibre or the finishing treatment, the characteristics and possibilities of the sensors may vary.
Drive for the progress comes from the areas of chemical, fibre, textile, coating and micro-technology as well as from bioengineering and materials science. [18] Recommendation for future prospects.

Introduction Compared with traditional metal materials, such as steel, aluminum and titanium, composite materials are used extensively in marine and aerospace structures due to their higher specific strength and specific stiffness, lower density and flexibility in design.
At present, laminated composite materials are the main practical application of composite structure.
Different materials have different loss factor, so that how to make the kinetic energy of oscillation converting to other forms of energy (for instance, heat energy, deformation energy), and how to make the system restore pre-stimulated state are the considerations during the design of laminated composite materials structural.
During the design of material structure, choosing the relatively low fiber volume fraction of the structure can improve the damping property of laminated composite materials.
