Description
Technical field
The utility model belongs to fiber reinforcement stratiform composite structure, relates in particular to the fiber reinforcement stratiform composite structure with anti-hierarchical nature.Utilize unidirectional or multidirectional fiber single layer cell by rolling into or be folded into the construction unit that has fiber to pass through at thickness direction, and with these unit organic assembling in addition, thereby make the Fiber Laminated reinforced composite structure have needed anti-vertical resolution.
Background technology
Engineering material as a kind of advanced person, composite particularly fibre reinforced composites is progressively replacing traditional engineering material (as metal material and timber) and is being widely used in the industrial circles such as space flight, aviation, navigation, building, automobile, physical culture and medicine equipment, because this class material has the characteristics such as lightweight, that specific stiffness is large, specific strength is high, the life-span is long, corrosion-resistant, designability is good, except being used for sheet cover, also be used for more and more structural bearing spare.Although the complex method of fibre reinforced composites constantly makes new advances, the most widely used layered composite structure form that remains.This class composite structure is usually used one group of thin ultimate fibre laminate (unidirectional fibre or multidirectional fiber, braiding or non-woven, resin prepreg or non-preimpregnation), lay in a certain order also after corresponding manufacturing procedure is solidified, the interlayer matrix is bonded together each laminate, thereby obtains the member of required shape and size.Obviously, due to the particularity of composite material manufacturing process, resulting structural member just has advantages of that traditional engineering material can't realize.For example, can be formed in by quantity or the direction that changes every layer of fiber the structure that different directions has different performance, thereby when satisfying the structural bearing needs, obtain the lightest construction weight, this has very important realistic meaning to the Modern Manufacturing Industry that turns to target with light weight.
but, due to fibre reinforced composites use high-performance fiber and performance a little less than the own characteristic that combines of matrix material, if material internal solidifies bad or exogenous impurity is arranged, when running into iterative cycles load or shock loading, matrix itself just easily destroys, its adjacent fiber just might can't remain on original position or original given direction, particularly at the shear stress that exists along the interlayer direction, be very easy to cause interlaminar separation, formation is as micaceous layer structure, thereby affect the bearing capacity of laminar composite structural member, limit them in popularization and the use of wide spectrum and special occasions more.Layering as the modal a kind of failure mode of laminar composite layer, is composite science technical field outline always, and the technical measures of many raising composite delamination failure drags are arisen at the historic moment.Common method has: matrix modification is toughness reinforcing, interlayer short glass fibre (or plastic particle) is toughness reinforcing, key stratum blocks (stoping the shear stress transmission), rigid layer replacement, laying order optimization, interlayer stitching, 3 D weaving, edge coating enhancing (as US Patent No. 6277463B1, US6544366B2 and US20010053432A1) etc.It is improvement on above-mentioned technical foundation that some other method strengthens mutually the inlaying of (cut off along horizontal plane after 3 D weaving, thereby stay vertical short fiber at thickness direction), vertical z-axle pinning technology (inserting fiber rod or peg or wire at thickness direction), interlayer irregular interface (as US Patent No. 6333092B1) etc. also mostly as 2.5 dimension braidings.In a word, although these technical measures all have certain effect in actual applications, more or less also exist various deficiencies.Some is that in modulus of shearing, tensile strength or other face take expendable material, performance is cost, and some has increased the weight of member widely; Many technical measures not only make manufacturing cost increase substantially, and the technical process very complex, implement relatively difficulty.
