초록

Provided are a heat-resistant glass fiber which has excellent heat resistance, which is also easy to spin and less expensive and which is suitable as an acoustic material for use in an automobile muffler, and a process for the production thereof. The heat-resistant glass fiber has a composition comprising, substantially by weight %, 56 to 58.5% of SiO2, 12 to 17% of Al2O3, 16 to 27% of CaO, 1 to 9% of MgO, 0 to 1% of Na2O and 0 to 1% of K2O as the entirety of the fiber and containing neither B2O3 nor F2, and has a surface layer portion made of a silicic ...

1. A heat-resistant glass fiber which has a composition consisting of, by weight %, 56 to 58.5% of SiO2, 12 to 17% of Al2O3, 16 to 27% of CaO, 1 to 9% of MgO, 0 to 1% of Na2O and 0 to 1% of K2O as the entirety of the fiber and containing neither B2O3 nor F2, and which has a surface layer portion made of a silicic glass having an SiO2 content of at least 90% by weight, wherein the fiber substantially retains its flexibility when heated for ten hours at 900° C.2. The heat-resistant glass fiber of claim 1, wherein the surface layer portion made of a silicic...
