Manufacturing 3D Spacer Fabric for Insulating Oil Pipelines

This paper provides a major challenge, Because of many bad conditions that effect oil pipelines properties, this paper discuss the ability of manufacturing and applying the 3D woven spacer composite fabric for insulating oil pipelines. This paper talks over the thermal, chemical, and mechanical properties of the final product from the 3D Spacer Fabric and the polymer resin matrix. And finally, this paper gives an idea how and with any kind of weaving machines these fabrics can be made.

The Effect of Changing Construction Materials Systems of Walls on the Environmental Performance of Buildings

In this paper, the thermal performance of the doctors and nurses housing building in Aleppo walls, consisting of the hollow blocks with inside styropor sheet and compare it with a wall consisting of hollow blocks with eternal continuous insulating styropor layer and the effect of adding continuous insulating layer on the existing walls. The study showed that the use of the block with inside styropor slice was not useful regarding the thermal behavior and causing large and intense thermal bridges generation. However the use of block with continuous styropor layer made the temperature distribution more uniform and reduced the energy flux by 36.7-70%.
