Description
Technical field
The invention belongs to Composites Molding Techniques, relate to the improvement to the mould of the I-shaped reinforcement of large-sized composite material.
Background technology
The structure of composite material I-shaped reinforcement is referring to Fig. 1.I-shaped reinforcement is comprised of upper limb, lower edge and web three parts, the upper limb that is positioned at the web left side is the left flange of upper limb, the upper limb that is positioned at web the right is the right flange of upper limb, and the lower edge that is positioned at the web left side is the left flange of lower edge, and the lower edge that is positioned at web the right is the right flange of lower edge.At present, the mould of composite material I-shaped reinforcement generally comprises pretreatment mould and mould.Fig. 2 is pretreatment mould structure schematic diagram, and in figure, 18 is half I-shaped reinforcement, and the center line of web of take is die joint; The 14th, pretreatment core, its upper surface and the laminating of reinforcement web; The top of left surface and the laminating of reinforcement lower flange, the top of right flank and the laminating of reinforcement upper flange; The 15th, left plate, the 16th, right plate, the 17th, upper cover plate.The bottom surface of the right flank of left plate 15 and reinforcement lower flange fits, the upper surface laminating of the left surface of right plate 16 and reinforcement upper flange, the die joint laminating of the lower surface of upper cover plate 17 and reinforcement web.Half I-shaped reinforcement of the each processing of this pretreatment mould.Fig. 3 is current I-shaped reinforcement mould, and it is comprised of left moulding master mould 2a, right moulding master mould 3a, bed die 9, upper cover plate 8, rubber upper left rib 10, rubber upper right rib 11, rubber lower-left rib 12 and rubber bottom right rib 13.The upper surface of bed die 9 is with the profile of I-shaped reinforcement 1 lower edge; Left moulding master mould 2a cross section is quadrangle, the profile of left moulding master mould 2a upper surface is consistent with the left flange lower surface of corresponding I-shaped reinforcement 1 upper limb, left moulding master mould 2a lower surface profile is consistent with the left lug upper surface of the lower edge of corresponding reinforcement, the right flank of left moulding master mould 2a is plane, the left surface laminating of it and reinforcement web, the left surface of left moulding master mould 2a is plane; Right moulding master mould 3a cross section is quadrangle; the profile of right moulding master mould 3a upper surface is consistent with the right flange lower surface of corresponding I-shaped reinforcement 1 upper limb; right moulding master mould 3a lower surface profile is consistent with the right lug upper surface of the lower edge of corresponding reinforcement; the left surface of right moulding master mould 3a is plane; the right flank laminating of it and reinforcement web, the left surface of right moulding master mould 3a is plane; Upper cover plate 8 is rubber soft modes that AIRPAD rubber forms through sulfuration, the length that the length of upper cover plate 8 is the reinforcement upper limb, the width of the width that the width degree of upper cover plate 8 is the reinforcement upper limb, rubber upper left rib 10 and the width sum of rubber upper right rib 11; Rubber upper left rib 10 is fitted with the left surface of the left flange of upper limb, the length that the length of rubber upper left rib 10 is the reinforcement upper limb, the thickness of rubber upper left rib 10 and upper limb consistency of thickness; Rubber upper right rib 11 is fitted with the left surface of the right flange of upper limb, the length that the length of rubber upper right rib 11 is the reinforcement upper limb, the thickness of rubber upper right rib 11 and upper limb consistency of thickness; Rubber lower-left rib 12 is fitted with the left surface of the left flange of lower edge, the length that the length of rubber lower-left rib 12 is the reinforcement lower edge, the thickness of rubber lower-left rib 12 and lower edge consistency of thickness; Rubber bottom right rib 13 is fitted with the left surface of the left flange of lower edge, the length that the length of rubber bottom right rib 13 is the reinforcement lower edge, the thickness of rubber bottom right rib 13 and lower edge consistency of thickness.The shortcoming of this mould is: the first, on reinforcement, the width of lower edge must leave surplus, after moulding, by machining, surplus is excised, and has increased workload, has reduced the utilization rate of material.If made allowance not, be difficult to guarantee the Forming Quality of lower edge on reinforcement; The second, the moulding of reinforcement needs two molds, i.e. pretreatment mould and mould, and cost is higher; Three,, because rubber upper left rib 10, rubber upper right rib 11, rubber lower-left rib 12 and rubber bottom right rib 13 are all unvulcanized AIRPAD rubber, therefore, this mould can not be for a co-curing of reinforcement and covering.
In addition, composite expands to stressed and larger-size main force support structure (as empennage, wing and fuselage etc.) in the application of aviation field from stressed and the less inferior load-carrying construction (as the rudder face structure) of size, and the manufacture of Composite Material Stiffened Panel is had higher requirement.The assurance of reinforcement linearity and position degree is one of key manufacture in large scale fibre reinforced composites wallboard forming process.But, along with the size of Composite Panels becomes large, it is large that the length of its reinforcement also becomes thereupon, can reach several meters.When the size of reinforcement is larger, the reinforcement shaping mould just is difficult to processing, even process, because rigidity is very little, is easy to distortion, can't guarantee the formed precision of Composite Material Stiffened Panel.
