Glass fiber pipe

Abstract

The utility model discloses a glass fiber tube which comprises an axial glass fiber layer, a longitudinal glass fiber layer and a silica gel layer. The axial glass fiber layer comprises a plurality of axial glass fibers which are arranged in parallel, the longitudinal glass fiber layer comprises a plurality of longitudinal glass fibers which are spirally wound on the axial glass fiber layer, the axial glass fibers and the longitudinal glass fibers have no cross points, and the silica gel layer covers the outer surfaces of the axial glass fiber layer and the longitudinal glass fiber layer. No cross point exists between the axial glass fibers and the longitudinal glass fibers of the glass fiber pipe, so that stretching and weaving of the fibers are reduced, and breakage and burrs of the fibers are reduced. Compared with a traditional glass fiber pipe formed by weaving axial glass fibers and longitudinal glass fibers in a crossed mode, the expansibility of the glass fiber pipe is improved through the axial glass fibers which are arranged in parallel, and the axial stretchability of the glass fiber pipe is improved through the longitudinal glass fibers which are spirally wound.
