From WO 2011/096805 A1 it is also known that a kind of apparatus and method for manufacturing reinforcing fiber product.Specifically, It is disclosed that the reinforcing fiber joint product of annular.
Wheel rim for carrying tire has employed for a long time on vehicle.This wheel rim is used for oil-engine driven car , such as automobile, truck or other multifunctional vehicle, and it is also used for the vehicle of muscular motivation, such as, bicycle.
It has therefore proved that different the materials aluminium wheel rim, steel wheel rim, titanium wheel rim and the institute that are known as in bicycle art Composite material wheel rim referred to as is successful.Generally, these composite material wheel rims can be considered the wheel rim including different materials.This The specific subclass type planting composite material wheel rim is also fibrous composite wheel rim, i.e. (such as, this wheel rim uses reinforcing fiber Chopped fiber or long fibre).Generally, fiber is embedded in resin.During manufacture is processed, resin is hardened to make Complete wheel rim entirely.Surface in one or several process steps again, to the wheel rim product completing comprising reinforcing fiber It is very common for carrying out processing, and these surface treatments are also abrasive type.
In 20 years of past, the advantage of fibrous composite wheel rim becomes apparent.After all, compare by other The wheel rim that material is made, this wheel rim more light weight and harder.It is proved this wheel rim especially in race bicycle, iron-man triathlon It is successful in the high-end field of bicycle and mountain bike.
Regrettably, currently available fibrous composite wheel rim is still prohibitively expensive, and for hardness and light weight For change, can optimize further.
The invention solves the problems that being just this, present invention focuses on removing or at least reducing defect known to these.Specifically Ground it is proposed that can machine-made wheel rim and can be used for making the method for this wheel rim, compared to conventional wheel rim, the method increases Implicit costs (cost potential), and for hardness and lightweight, the method improve wheel rim.
Content of the invention
Solving this problem, (preferably, the method for the present invention includes the step of following species to the method according to the invention One step is applied with connecing a step)：
A) provide for example, the possible resistance to compression being made up of steel alloy and the first mould of temperature resistance,
B) insert in the first mould by least two single layers (such as with knitting, that net is knitted, braiding or non-volume The mode of woven fabric) form first plane reinforcing fiber encapsulation, this first plane reinforcing fiber encapsulation such as include glass fibers Dimension, aramid fibre and/or carbon fiber, or be made up of glass fibre, aramid fibre and/or carbon fiber,
C) one or several reinforcing fiber pads are inserted in the first mould on the first reinforcing fiber encapsulation, this enhancing is fine Dimension pad is mainly made up of reinforcing fiber,
D) insert by least two individual courses (such as with pin in the first mould on one or several reinforcing fiber pads That knit, net is knitted, braiding or non-woven fabric mode) form second plane reinforcing fiber encapsulation, this second plane increase Strong fiber encapsulation includes such as glass fibre, aramid fibre and/or carbon fiber, or by glass fibre, aromatics polyamides Amine fiber and/or carbon fiber composition,
E) insert distance piece in the first mould,
F) by means of the resistance to compression for example, being made up of steel alloy and temperature resistance the second mould closing the first mould, and
G) for example, raised come the Rotating fields that harden by means of pressure rise and/or temperature, open the first mould and/or second Mould (multiple mould) and take out wheel rim, this Rotating fields comprises the reinforcing fiber being obtained by the step executing before.
This complexity layer/Rotating fields can be easily achieved using machine.This shortens Production Time.Even if with known The wheel rim of light weight compares, and this wheel rim weight does not change substantially yet, but achieves dramatically increasing of hardness.Considerably beyond at present Commercially available hardness factor.Due to the design of regulating load, convenient feature still will not deteriorate can be improved on the contrary.
Advantageous embodiment described in greater detail below.
For example, before step b) and/or after step a), will fold along line/(space) curve/edge/straight line/ Downwardly turn over be made up of reinforcing fiber the first continuous two-sided fabrics/materials (such as, knitting, net is knitted, braiding or Non-woven fabric) insertion the first mould in be favourable, this reinforcing fiber such as includes glass fibre, aramid fibre And/or carbon fiber, or it is made up of glass fibre, aramid fibre and/or carbon fiber.Then, can achieve especially needs Machine direction/the orientation of orientation.
For the load capacity of wheel rim, before step f) and/or after step e), will be along line/(space) curve/side Edge/straight line and the second continuous two-sided fabrics/materials of being made up of reinforcing fiber of folding/downwardly turn over (such as, knitting, net Knitting, braiding or non-woven fabric) be favourable in insertion the first mould, this reinforcing fiber such as include glass fibre, Aramid fibre and/or carbon fiber, or be made up of glass fibre, aramid fibre and/or carbon fiber.
