Description
Technical field:
The present invention relates to the reinforcing material ply angles of a kind of composite material drawing and extruding section bar, composite material drawing and extruding section bar particularly can be made to have the reinforcing material ply angles of excellent combination mechanical performance.
Background technology:
Composite material drawing and extruding section bar has lightweight, the good characteristic such as high-strength, corrosion-resistant because of it, and people substitute traditional shape at some industry fields with it.But general composite material drawing and extruding section bar is because being limited by reinforcing material form and pultrude process etc. so that it is longitudinal mechanical performance is typically much stronger than its horizontal mechanical performance, it is typically its longitudinal mechanical performance in other words and has a surplus and horizontal mechanical performance deficiency；When as structural shape for manufacturing the higher engineering component of bearing requirements or building structure, the comprehensive mechanical performance of general composite material drawing and extruding section bar cannot reach the bearing requirements of engineering component or building structure, this phenomenon such as destruction, failure by shear that easily bend under the effect of load of drawing and extruding section bar, even destroys so that engineering component or building structure exist potential safety hazard.
Summary of the invention:
The present invention provides the reinforcing material ply angles of a kind of composite material drawing and extruding section bar, in order to improve the comprehensive mechanical performance of this section bar, particularly make its longitudinally, laterally intensity tend to equilibrium and improve the transverse bending strength of this section bar, transverse compression intensity and shear resistance, thus overcome that general composite material drawing and extruding section bar is usually present " longitudinal mechanical performance have a surplus and laterally mechanical performance not enough " defect.
nullThe present invention solves the technical scheme that the problems referred to above are used: reinforcing material laying is five-layer structure，In this five-layer structure，With from top to bottom or by outer and in as sequence，Wherein ground floor、Third layer、Layer 5 is glass fiber cloth layer，Arbitrary tissue layer in this three glass fiber cloths layer there is glass fibre+45 ° in the composition of an at least tissue layer、90°、-45 ° of triaxial fabrics，This glass fibre+45 °、90°、-45 ° of its thickness ranges of triaxial fabric are 0.2～0.5mm，The composition of the arbitrary tissue layer in this three glass fiber cloths layer can be by glass fibre multi-axial fabric、Glass fiber composite mat、Glass chopped strand mats、The fabrics such as glass fibre continuous felt are individually constituted or matched combined is constituted，The thickness range of the arbitrary tissue layer in this three glass fiber cloths layer is 0.2～0.9mm；Wherein the second layer, the 4th layer be fibre glass roving layer, the thickness of this two fibre glass rovings layer can be identical or differ；This reinforcing material ply angles is particularly suited for manufacturing section bar wall thickness or composite material drawing and extruding section bar that thickness is 5～8mm.
Ground floor, the outer surface of layer 5 glass fiber cloth in reinforcing material ply angles also can respectively add one layer of surface of polyester felt.
Reinforcing material used in reinforcing material ply angles is in addition to fibre glass roving, glass fiber cloth, it is also possible to be other fiber roving or fabric, such as carbon fiber, basalt fibre and fabric thereof etc..
The invention has the beneficial effects as follows: use the composite material drawing and extruding section bar of this reinforcing material ply angles manufacture to have the vertically and horizontally comprehensive mechanical performance more equalized, particularly can improve the transverse bending strength of this section bar, transverse compression intensity and shear resistance, thus the longitudinal mechanical performance overcoming general composite material drawing and extruding section bar to be usually present is had a surplus and the defect of horizontal mechanical performance deficiency, to meet purpose project component or the building structure performance requirement to composite material drawing and extruding section bar.
