Abstract
The invention relates to a method for preventing a carbon fiber composite wallboard from being drilled and layered. According to the technical scheme, a Y330 carboloy metal tool should be chosen as a drilling tool, an ejection block is used for abutting against the wallboard so that the working face of the ejection block can be tightly attached to the surface of a part, when an initial hole is drilled, a drill bit should be perpendicular to a structure surface, and when drilling-through is nearly achieved, a feeding speed should be lowered. The structure of the ejection block is that the diameter of the working face is 50-70mm, the thickness of the ejection block is 25mm, and a tail handle is arranged on the rear portion of the ejection block for handholding. The ejection block is used in the method, drilling of the carbon fiber composite wallboard supported without metal parts is achieved, the damage such as layering and cleaving can be effectively avoided, and meanwhile drilling quality is guaranteed.
Description
Technical field
The present invention is directed to carbon fibre composite wallboard assembling field, is a kind of to avoiding the method for layering in the carbon fibre composite wallboard boring procedure.
Background technology
Because quality is light, high specific strength, high ratio modulus, endurance, corrosion-resistant, a series of excellent properties such as high temperature resistant and dimensional stability is good, carbon fibre composite has been widely used in aircraft industry, but also there is certain weakness in it, and crisp (breaking strain only is 1%-3%), interlaminar strength are low, impact resistance difference etc.Therefore, the main damage of carbon fibre composite part in assembling process be delamination damage and wallboard in the splitting of drill bit exit, if delamination damage is serious, will influence intensity and the fatigue life of part.
Summary of the invention
In order to address the above problem, the invention provides a kind of method of avoiding carbon fibre composite wallboard boring layering.Adopt method of the present invention can avoid part layering and wallboard at drill bit in the exit splitting.
The technical solution used in the present invention is: a kind of method of avoiding carbon fibre composite wallboard boring layering, and step is as follows:
1) drilling tool should be selected Y330 Talide class cutter for use;
2) withstand wallboard with jacking block, make the working face of jacking block be close to piece surface, when boring just the hole, drill bit should be perpendicular to body structure surface, should slow down feed speed when approaching to bore when saturating;
Above-mentioned a kind of method of avoiding carbon fibre composite wallboard boring layering, the structure of described jacking block is: the working face diameter is 50-70mm, thickness 25mm, the rear portion has caudal peduncle to be used to hand.
The invention has the beneficial effects as follows: by the method that adopts jacking block to make the carbon fibre composite wallboard that no metal parts supports is holed, can effectively avoid the generation of layering, splitting equivalent damage, guarantee the quality of boring simultaneously.
Description of drawings
Fig. 1 is the structural representation of jacking block among the present invention.
The specific embodiment
A kind of method of avoiding carbon fibre composite wallboard boring layering of embodiment
Step is as follows:
1) be illustrated in figure 1 as a kind of jacking block, its structure is: working face (1) diameter is 50-70mm, thickness 25mm, and it is hand-held that the rear portion has caudal peduncle (2) to be used for;
2) drilling tool should be selected Y330 Talide class cutter for use;
Withstand wallboard with jacking block, make the working face of jacking block be close to piece surface.When boring just the hole, drill bit should be perpendicular to body structure surface, should slow down feed speed when approaching to bore when saturating.
Claims (2)
