Mechanical Properties of Window Frames Exposed to High Temperatures

This study aimed to examine the risks from window frames installed in opening of an outer wall when exposed high temperatures and secure DB through tests on thermal tensile strength characteristics different materials. Al6063-T5 was tested up 600 ℃ at intervals 100 ℃. Changes properties decreases occurred rapidly 400 The measured as 84.41 MPa, i.e., 34.1% that room temperature (the maximum test temperature). In case polyvinyl chloride, were conducted 70 10 found be constant did not significantly affect increase temperature. However, decrease proportional. strength, a 14.98 MPa (45% temperature)
