英文摘要 | Laboratory-scale wooden fire door was made from plywood and six kinds of inorganic materials by using different combinations of raw material and construction process. The objective of this study was to evaluate the fire resistancy of the wooden door with various incorporation processes. The standard method of CNS 11227 depicted as “Method of fire resistance test for fire door of building” was used to examine the fire resistance duration of the door during 30 and 60 minutes heating tests. One third of the 15 manufacturing processes designed to meet the 30 minutes heating grade was successful while 40% of the other 15 designs passed the 60 minutes rating. Factors affecting the fire resistance duration were specimens thickness and kinds of core and sub-central materials. The specimens thickness were L6-L15>L1-L5, D6-D15>D1-D5, the kinds of core materials were ceramic fiber>glass fiber carpet>rock fiber>glass fiber and plywood and the sub-central materials were magnesium oxide board plywood. Most of the failure in the specimens derived from severe becoming degradation of both the exposed and un-exposed surfaces of the tested specimens. Cracking in and falling-apart from the surfaces thus failed the impact test. Only 1/3 to 1/2 of the whole thickness of the fire doors was carbonized when higher density wood species such as Batu was used as the frame corner support. The resulted specimens wre able to pass the ten kilogram impact test owing to the retained strength performed by the uncabonized portion. |
