Problems solved by technology

Since the multi-axial fabric has a certain curvature when applied to the generator blade, the multi-axial fabric is a plane in the existing detection method, so there is a certain discrepancy between the detection results and the actual application
Secondly, when applying epoxy resin, because the curing temperature of epoxy resin is higher than the ambient temperature, the existing detection methods cannot meet the detection requirements of multiaxial fabrics

Abstract

The invention discloses a constant temperature heating device, which is used for detecting multi-axial fabrics for wind turbine blades. The constant temperature heating device comprises a fiber reinforced plastic mold, a constant temperature water tank and a heating layer, wherein the fiber reinforced plastic mold has an arc surface matched with an appearance of the wind turbine blade; the constant temperature water tank comprises a water tank, a heating device and a water pump; the heating layer comprises a heating conductive medium and a heating pipe; the heating conductive medium is formed by mixing aluminum powder and a resin, and is coated at the bottom of the fiber reinforced plastic mold; and the heating pipe is laid in the heating conductive medium and is connected with the constant temperature water tank. Compared with a heating device in the prior art, the constant temperature heating device has the advantages that: the fiber reinforced plastic mold has the arc surface, the arc of the arc surface is the same as that of the blade, and when the multi-axial fabrics are laid on the fiber reinforced plastic mold with the arc surface and detected, the condition is similar to a condition in the actual application process, and the detection result is more reliable.

Description

technical field [0001] The invention relates to the technical field of material detection equipment, and more specifically, to a constant temperature heating device. Background technique [0002] Multiaxial fabric is a base fabric obtained by fixing warp knitted fabrics together. It consists of one or more layers of parallel and straight yarns. Each layer of yarns can be arranged in different directions, and its density can be adjusted. Different, and the yarn can be combined with fiber mesh, film, foam or other materials to form a three-dimensional network overall structure. Since the multiaxial fabric is lined with non-looped parallel stretched yarns along the oblique direction, the multiaxial fabric not only has good performance in the transverse and longitudinal directions, but also can bear a large tensile force in the oblique direction. For the blades of wind power generators, since the direction and magnitude of wind in nature are unstable, multi-axial fabrics are ve...
