จากข้อด้อยที่กล่าวมาข้างต้น จึงมีแน

From the cons mentioned above is a concept in development of complex material that contains the main material is a polymer (Polymer matrix composite) is used instead, since the basic polymer properties is the best heat insulation. Has the ability to absorb sound and relatively light weight? There is a possibility that it will be used instead of a steel sheet roof. To get rid of these cons.

The disadvantages mentioned above. The concept of developing a composite material is a polymer (Polymer matrix composite) was used instead of the basic properties of the polymer has a good thermal insulator. Have the ability to absorb sound. And a relatively light-weight There is a possibility that will be used instead of sheet steel roofing. To eliminate such weaknesses

From the drawbacks mentioned above. The development of composite materials with the main material is a polymer (Polymer matrix composite) instead. Because of the basic properties of the polymer has a good thermal insulation.And the weight is light. There is a possibility to be used instead of steel sheet roofing. To eliminate the drawbacks thereof.
