Abstract
The invention relates to a reinforcing material paving layer structure for composite material pultrusion profiles. The paving layer is divided into five layers, wherein the first layer, the third layer and the fifth layer are glass fiber fabric layer; the second layer and the fourth layer are glass fiber rough yarn layer; fabrics of which glass fibers are in three axial directions including a direction of +45 degrees, a direction of 90 degrees and a direction of -45 degrees exist in at least one of the three glass fiber fabric layers; the thickness range of the fabric is 0.2-0.5 mm; and the thicknesses of the glass fiber rough yarns in the two glass fiber rough yarn layers can be the same or different. The composite material pultrusion profiles manufactured by the reinforcing material paving layer structure has balanced longitudinal and transverse comprehensive mechanical properties, and particularly, the pultrusion profiles have good transverse bending strength, transverse compression strength and shear capacity to meet requirements of target engineering components or building structures to properties of the composite material pultrusion profiles.
Description
Technical field: [0001] The invention relates to a reinforced material lay-up structure of a composite material pultrusion profile, in particular a reinforcement material lay-up structure capable of making the composite material pultrusion profile have excellent comprehensive mechanical properties. Background technique: [0002] Because of its light weight, high strength, corrosion resistance and other excellent properties, composite pultrusion profiles have been used to replace traditional metal profiles in some industries. However, the general composite pultrusion profile is limited by the shape of the reinforced material and the pultrusion process, so its longitudinal mechanical properties are usually much stronger than its transverse mechanical properties, or usually its longitudinal mechanical properties are sufficient but its transverse mechanical properties are insufficient; When it is used as a structural profile to manufacture engineering components or building stru...
