<p>PROBLEM TO BE SOLVED: To cause a non-combustible sheet to have a non-combustible characteristic not ignited at a high temperature and further to enable it to be used as a free piping work by a method wherein a sheet-like mica is sandwiched between inorganic high strength reinforcing sheets having high intensity and both of them are adhered by adhesive agent. SOLUTION: A sheet-like assembled mica 3 is sandwiched between non- organic strength reinforcing members 1, 1'. The inorganic strength reinforcing members 1, 1' and the sheet-like assembled mica 3 are adhered by adhesive agents 2, 2' consisting of a silicone resin. As the sheet-like assembled mica 3, the mica is processed into a paper-like form without using any reinforcing agent, adhesive agent or other additive agent and this assembled mica may preferably be used. As the inorganic strength reinforcing members 1, 1', it is sufficient to alloy the material quality that it has a high durability against bending, it is adhered to the mica in a relative easy manner and has non- ignitable characteristic not ignited at 800 deg.C, and so it is not restricted in particular.</p> |
