It was observed that PBS/NR composites are green-composites or eco-materials.
The development of biodegradable polymeric materials has been a subject of great research challenge in materials science.
Experimental part Materials.
These results show that PBS/NR composites are environmentally friendly and degradable materials that can be considered as alternatives to non-biodegradable plastic materials for applications.

The Ministry of Human Resource of Malaysia reported that the most common type of accidents was workers falling from elevated heights and materials falling on the workers [1].
Therefore, study of hazards at construction site can become a guideline for the contractors and organisations to prevent accidents by analyzing the condition of materials and machinery used.
Culture involves learned and shared behaviours, norms, values, and material objects [12].

FATIGUE AND FRACTURE CHARACTER OF METAL RUBBER MATERIAL Yuming LI1,a, Hongbai BAI1,b JianchunYANG2,c 1University of Ordnance Engineering, China 2University of Science and Technology Beijing, China aliyuming1976@sina.com, bbhbk11@sina.com, cyjc675266@163.com Keywords: Metal rubber, Damaging Factor, Fatigue Test, Fracture Face, Electronic Scanning Microscope Abstract.
Introduction With the development of science and technology in space, the spacecrafts usually work in the worse circumstance such as high or low temperature, so they need to improve their components’ performance of vibration and sealing.
A main reason may be that it is a kind of particular materials, the testing measures and theories of metal material can’t be used here.
The fracture and fatigue character of MR is different from the metal material.
