Abstract

An enhanced laminated canvas having improved directional tensile properties includes an outer layer having a reinforcing material sandwiched between and bonded or bonded thereto. The reinforcing material comprises a first, a second, a third and a fourth layer of substantially parallel strands. The strands of the first and second layers extend parallel and transverse to the longitudinal axis of the outer layer material, respectively, and are non-woven and non-knitted. The strands of the third and fourth layers extend obliquely to the strands of the first and second layers, respectively aligned at first and second acute angles to the longitudinal axis. The canvas is produced by a continuous process in which the strands forming the layers are introduced separately but substantially simultaneously. Also disclosed are laminated canvasses reinforced with yarns consisting of UHMWP fibers and an adhesive capable of bonding these strands, in the absence of fibers of other materials.

Description

The lamination canvas that strengthens

Technical field

The utility model relates to a kind of enhancing canvas, especially, relates to the lamination canvas.

Background technology

Usually; The maintenance of aerofoil profile is vital for navigation performance, and natural or the routine braiding (woven) of artificial synthetic fibers, knitting (knit) or scrim canvas (scrim sailcloth) under load, are easy to occur because the unwanted distortion that the nonlinear interaction power on canvas causes.In the design of sail, in using material different and in the method for structure sail, obtained some progress, all be intended to limit the distortion of canvas under load.Although ongoing improvement allows fine and close more structure, the braiding canvas has the characteristics of orientation stretching.For example, in fact, loom makes warp crooked around the parallel fiber that keeps straight line.Consequently, the low elongation quality in weft direction, but when the length of the increase of curling is drawn out under load, its under tension force little through the hardness that makes progress.

The lamination canvas that DE4010086 describes comprises outer membrane, between outer membrane, clips second and the 3rd layer of enhancing strand that braided fiber strengthens the stretch-proof material of sheet and parallel spaced apart.The warp thread of braided fiber and weft yarn vertical and horizontal ground are arranged, and second and the 3rd layer strand aligns obliquely, and the longitudinal axis of braided fiber is acutangulated.This canvas has good deformation property, and fortifying fibre and strand also give film anti-character of breaking.Yet it is relatively thick that braided fiber strengthens sheet, and have directed tensile properties.The purpose of the utility model is to overcome or roughly improves these shortcomings or improved canvas is provided more at large.

The yarn of the lamination canvas that is used to strengthen should have high tenacity, high-modulus, low-density and good UV resistant performance.Such material is ultra-high molecular weight polyethylene (UHMWP), but because this material has self-lubricating property, it can not obtain gratifying adhesive bond in the past.A solution allows to use and comprises UHMWP, mixes the complex yarn that forms the UHMWP fiber with the material with better bonding characteristic (like polyester or carbon fiber).Yet this makes yarn and canvas become original possible thicker than them because for given nominal yarn diameter, these complex yarns compare with independent UHMWP yarn have lower toughness, lower modulus and higher density.

Fig. 2 and 3 schematically explains the quantity-produced apparatus and method that are used for according to the laminates of the utility model.Comprise that outer 11,12 continuous film distributes from roller (not shown) separately, and through deflector roll 33 (etc.) be fed into the opposite side of a pair of

pinch roll

30,31, at least one of the apparent surface of film scribbles adhesive.At least one of

roller

30,31 can be heated with softening

adhesive.Pinch roll

30,31 is driven so that its edge synchronously moves by the motor (not shown), and traction is through

film

11,12 and strand 14-17.Roller 30, the spacing between 31 are adjusted to provide enough pressure so that each layer is bonded together, and produce the lamination cloth 10 that strengthens.The cutter (not shown) can be pruned the edge of the lamination cloth 10 of new formation, finally is cut into suitable length and configuration, to process finished product, such as sail.

The vertical strand 14 of length feed machine 35 feedings is to roller 30,31; And comprise a plurality of laterally spaced deflector roll (not shown)s (each deflector roll and roller 36 cooperation guiding strand 14 separately); And relevant bobbin (not shown) and the regulating wheel (not shown) of strand from wherein distributing.

The horizontal strand of traverse feed machine 38 feedings 15 is to

roller

30,31, and is included in a pair of traveling bed 39,40 on the opposite side of equipment.Strand 15 is in conveyer belt 39, extension between 40, and conveyer belt 39,40 is synchronized driving to keep strand 15 parallel.Strand 15 extends around the stake (not shown) on the conveyer belt 39,40, on strand 15, extends continuously around each stake, in conveyer belt 39, extension back and forth between 40.Loading machine 41 comprise rotor (rotor upright axis rotation, with at conveyer belt 39, load strand between 40), and relevant bobbin (not shown) and the regulating wheel (not shown) of strand from wherein distributing.The coil setting that transmits around stake exceeds outer 11,12 edge and is repaired by cutter.

In roller 30, feeding between 31, feeding machine 45 aligns with respect to the direction of

roller

30,31 tensions with each strand another group strand by feeding machine 45.Move strand feeding machine 45 mean levels; Stride across right hand edge from the left longitudinal edge 46 of the

film

11,12 of outside; Thereby formed the strand 16 of layer 23; Stride across left hand edge 46 and move strand subsequently from right hand edge 47, thereby form the strand 17 of layer 24, repeat this action to produce lamination cloth 10.

Fig. 4 shows the sketch map of the feeding machine 45 be used to tilt strand, and feeding machine 45 comprises guidance set 46, and guidance set 46 is actuated to and feed bar 47 rotates.Strand is from being installed in the independent bobbin (not shown) feeding on the axis feeding bar 47, and with the regulating wheel (not shown), strand passes through regulating wheel.Guidance set 46 can be installed under the traverse feed machine 38, and comprises the endless belt 49 that is installed on the

sprocket wheel

51,52, and

sprocket wheel

51,52 is around parallel axes 50 rotations of upwards tilting towards roller 30,31.The strand that distributes from feed bar 47 forward roller 30 to, before 31, through combining to pass through with the bullport separately 48 that is arranged on on 49.Be with 49 with feed bar 47 synchronously so that both accomplish a turnover simultaneously.Bullport 48 thereby on 49 smooth upper and lower part vertically moves in the opposite direction, and single line once forms a strand 16, forms a strand 17 before this.Through adjustment with 49 with respect to the speed of

roller

30,31 and driven speed; Can be with the mode angle changing 19,20 of any needs,

angle

19,20 is formed by the strand of orientation in the directed strand in a direction in the finished product laminates and other directions.
