(3) mixture is placed in dragging-squeezing machine for fiberglass and carries out pultrusion to get required glass reinforced plastic.The drawing The temperature of extrusion forming is 200~220 DEG C, and environment temperature need to be maintained at 10~30 degrees Celsius, pultrusion speed=25+ (20- environment temperature Degree) × 0.85, unit: cm/min.
Combined with specific embodiments below, the preparation method of glass reinforced plastic is further explained.
Embodiment
1,16 groups of glass reinforced plastics are prepared according to the above method, carry out extrusion forming under the conditions of 210 DEG C of pultrusion temperature.Each group The practical preparation parameter of glass reinforced plastic is as shown in table 1, and the numerical value of each component refers to mass fraction in table.The curing agent 1, curing agent 2 It is purchased from Changzhou Chang Sheng glass-reinforced plastic material Co., Ltd, curing agent 1 is unsaturated-resin curing agent, and curing agent 2 is epoxy resin Curing agent.
The preparation parameter of 1 each group glass reinforced plastic of table is referring to table
2, the bending strength and shearing strength of each group glass reinforced plastic are tested, the results are shown in Table 2.
The performance of 2 each group glass reinforced plastic of table shows table
Glass reinforced plastic prepared by the present invention is also applied to specific Flying Area in Airport relevant device by inventor, and combines glass The characteristic of steel provides a kind of indication device for wind direction using the glass reinforced plastic.
As shown in Figure 1, a kind of indication device for wind direction, the pedestal 2 including being fixed on ground is solid vertically on the pedestal 2 Fixed hollow fragile stem 1, certainly, fragile stem 1 can also be fixed on other required positions or be directly fixed on ground.The fragile stem 1 material is the glass reinforced plastic, has stronger bending resistance, will not be rolled in the normal outdoor environment such as blowing and raining It is disconnected;Its anti-shear ability is weaker simultaneously, is very easy to fracture when by external force collision, be crushed, (i.e. to avoid damage impacting body Aircraft).Wind sleeve 4 is arranged in 1 middle and upper part of fragile stem.The wind sleeve 4 and 1 link position of fragile stem, the fragile stem 1 On, it is correspondingly arranged the rotary connector that wind sleeve 4 can be made around 1 axial-rotation of fragile stem.
Preferred scheme are as follows: uniformly distributed several frangible points 3 in the fragile stem 1, each frangible point 3 can be further improved frangible Frangible performance easy to break when bar 1 is impacted.Fig. 2,3 illustrate a kind of embodiment of the frangible point 3, wherein Fig. 2 is only opened up The side wall construction of fragile stem 1 is shown, arrow direction is external force direction.The frangible point 3 includes being arranged in 1 bar wall of fragile stem Interior broken bar device 31.As shown in figure 3, the broken bar device 31 is in funnel-shaped structure, broken 31 cross section of bar device is in 1 wall of fragile stem In thickness across with a thickness of the 2/3~3/4 of 1 wall thickness of fragile stem;It should be understood that the funnel depth of the broken bar device 31 is easy The 2/3~3/4 of broken 1 wall thickness of bar.Broken 31 cross section of bar device is in V-shape, and opening direction is described towards outside fragile stem 1 The hardness of broken bar device 31 is greater than the hardness of fragile stem 1, can be made of the strong material of stainless steel or other rigidity, weatherability.Make When with this embodiment, because frangible point 3 is combined closely with fragile stem 1, outside fragile stem 1, with not set frangible point 3 It is identical.In the masterpiece used time by large area such as wind-force in environment, when the stress condition of fragile stem 1 and not set frangible point 3 It is identical, still flexural strength with higher;When by external force collision, stress is relatively concentrated, the broken bar device 31 at frangible point 3 The funnel bottom that shock stress is focused on to broken bar device 31 further speeds up the broken of fragile stem 1.
Fig. 4 illustrates the another embodiment of frangible point 3.For in elliposoidal inside fragile stem 1 at the frangible point 3 Hollow structure, the wall thickness of the hollow structure circumferential direction are 2/3~5/6 of remaining position wall thickness in fragile stem 1.It should be understood that It is externally, identical when the pattern of fragile stem 1 is with not set frangible point 3 in this embodiment.In by environment When the effects of wind-force, the stress of fragile stem 1 also with not set frangible point 3 when it is identical;When by external force collision, stress collection In, it is more easily broken provided with the fragile stem 1 at frangible point 3.
Preferred scheme are as follows: the diameter of the wind sleeve 4 is different.Wind sleeve 4 from 1 connecting pin of fragile stem to outstanding End extends, and diameter successively decreases, in the small taper of mouth outsole.This structure makes the side windage area of wind sleeve 4 be greater than opening The wind area at (outstanding end).When blowing, wind sleeve 4 carries out axial direction under the action of the wind, by rotary connector around fragile stem 1 Rotation, until going to the opening direction face wind direction of wind sleeve 4, to play the role of identifying wind direction.
Preferred scheme are as follows: the rotary connector includes two the first swivel bearings for being fixed on 1 top of fragile stem 61 and it is fixed on two the second swivel bearings 62 of 1 middle and upper part of fragile stem.Pass through first between described two first swivel bearings 61 Connecting rod 71 connects.Second connecting rod 72 connects between described two second swivel bearings 62.
First swivel bearing 61 positioned at 1 the top of fragile stem is located at 4 lower end corresponding position of wind sleeve, remaining Three swivel bearings are respectively positioned on the not corresponding position of wind sleeve 4.It should be understood that being located at position in first swivel bearing 61 Higher bearing is set, position is in the lower section corresponding position of wind sleeve 4;Another first swivel bearing 61 is located at wind sleeve 4 The position being not directed to;The a part of first connecting rod 71 in fragile stem 1 is corresponding with 4 present position of wind sleeve, another part position In the position that wind sleeve 4 is not directed to.Two the second swivel bearings 62 and corresponding second connecting rod 72 are respectively positioned on wind sleeve 4 and do not relate to And position.Such positional relationship is more advantageous to the progress of wind sleeve 4 itself rotation, is also beneficial to fragile stem 1 to wind sleeve 4 Load-bearing.Meanwhile the rotation connection that 4 swivel bearings and two connecting rods are realized, preferable waterproof and dustproof can be played and made With avoiding water or impurity from entering inside the body of rod of fragile stem 1, to extend the service life of fragile stem 1.
Preferred scheme are as follows: be additionally provided with warning lamp 5 at the top of the indication device for wind direction.The warning lamp 5 can be electricity Pond power supply, or power supply is routed from outside by connecting to power supply power supply inside 1 body of rod of fragile stem, or directly.Warning lamp 5 and power supply Between be additionally provided with switch, or remote control is opened and closed by other remote controllers, to play a warning role.
