Continuous fiber bi-directionally reinforced adhesive plastic composite pipe

Abstract

The utility model discloses continuous fiber bidirectional reinforced adhesive plastic composite pipe, from inside to outside is plastic inner tube layer, bidirectional reinforced core layer, outer layer and reinforcing layer in proper order, bidirectional reinforced core layer is composed of multiple unit continuous fiber prepreg belt, and the first unit of bidirectional reinforced core layer includes at least two layers, and the first layer is tightly attached between the band and the band and is fused and attached on the plastic inner tube layer and is wound in the set angle alpha right direction along the plastic inner tube layer axial hot melt setting, the second layer is tightly attached between the band and the band and is fused and attached in the first layer laying seam middle and is wound in the set angle alpha right direction along the plastic inner tube layer axial hot melt, and the first layer of the second unit of bidirectional reinforced core layer is tightly attached between the band and the band and is fused and attached on the first group layer and is wound in the set angle alpha left direction along the plastic inner tube layer axial hot melt setting, the second layer is tightly attached between band and band and is fused and attached in the first layer laying seam middle and is wound in the set angel alpha left direction along the plastic inner tube layer axial hot melt setting, and multiple units are left and right staggered winding to form bidirectional reinforced core layer.
