DescriptionThe procedures for FRP hand lay-up as to the environmental conditions as stipulated in principle and the necessary instruct

2、ions. Environmental condition operation requirements1. Ply the preparation and examination before the operation1) Whether the location and external operations for the operator bracket construction is solid and reliable, is clean. 2) The operator tools and equipment should be complete, such as brush,

3、 including plates, pressure stick, iron, scissors and some other essential tools, and all the tools to check compliance with requirements. 3) Protective equipment: mask, gloves, clothing, overshoes, etc. complete and clean. 4) Ventilation: the reliability of work and ensure good ventilation in the s

4、pecific operation allows the use of ventilation, but the end of the construction should be closed immediately.5) Whether the gel layer of gel coat to tack appropriate. 6) Confirm the temperature and humidity of the workshop and record it.7) Confirm the Resin and fiberglass material is the appointed

5、manufacturer.2.The operation procedure of lamination A Paint to the cured gel coat The resin layer added the curing agent B Part of the corner filling with resin glass fiber bundlesC Lay the chopped strand mats （first layer）D Lay the glass fibre cloth （second layer ） E Maintenance and curing F Lay t

6、he chopped strand mats （Third layer） G According to the structure H Local reinforcement and rib made I Maintenance and curing3.Lamination requirements1) Instruction: Check the operation of the workers in the operation should be preceded by "overlay operating table" came a process is alread

7、y tested and qualified inspectors, prohibit the unauthorized operation. 2) Make sure gel coat has cured (with appropriate non-stick hand, cured gel coat is generally not more than 24 hours) to shop floor. 3) Overlay the first layer of resin used to add the right amount of gel coat color with the sam

8、e pigment paste, brush with infiltration in the transaction layer of thick coated resin-rich layer, then a layer of carpet surface. 4) For right angle, acute angle, there are no sharp corners of glass fiber cloth with a layer of gel coat can be filled in the acute area of glass fibers to form a cert

9、ain angle, then placement. 5) The first layer of ply should be very careful to repeatedly remove air bubbles and fully bonded with the gel coat layer, in order to avoid the formation of bubbles or other defects in products, mutual recognition of defect-free operator before laying a second layer, thi

10、s time by overlay structure required to achieve the required thickness, such as sub-sub overlay interval shall not exceed 24 hours.4. Shop floor quality control operation1) fabric placement application brush, including foam board or off the roll compaction and deaeration, along the radial fiber clot

11、h to the other end by the end of the regular press pressure, including the roll to eliminate air bubbles, such as fiber mats, with deaeration roll compaction and deaeration, including board hanged. 2) Should pay attention again before the overlay layer of fabric have been infiltrating resin, non-con

12、vex layer and the bubble phenomenon. 3) Does not allow stacking resin and fabric wrinkling phenomenon. 4) Transfer of fiber cloth between fabric width control 40-50mm, not allowed to butt joint, layer make meet dislocation, the space not less than 100-150mm.5) 4-5 Park in resin viscosity, the viscos

13、ity is too low infiltration deaeration easy, but it can cause the resin flow is not enough bonding strength of resin or glass fiber cloth shortage.6) The general control of resin content of 70% glass fiber mat, glass fiber cloth 50%. 7) Overlay interval is generally less than 24 hours, otherwise it

14、is secondary bonding, hair treatment should be playing, but no matter-like, as in the cured laminate or gel overlay, the first layer of glass fiber mat should be .8) For the keel reinforced, the joint position of thicken plate ,keel covered plate and shell plate is not allowed sudden change which sh

15、ould be on both sides of the filter to form gradually incline to thinning one by one, the layer space is general 10-15mm.5. Secondary bonding1) Secondary bonding is cured and already more than 24 hours after the fiberglass laminate on the shop floor, in this way in principle for the construction of

16、age on the hull, but the ribs in the repair of composite structure production and use. 2) Secondary bonding as follows: A. Secondary bonding adhesive surface should be increased as much as possible, preferably on its surface when the construction has not yet fully cured. B. Completely hardened after

17、 the second adhesive bonding surface must be clean of grease, stolen goods, such as grinding with the grinding surface to play, or chisel to remove the surface, such as glass fibers exposed after construction. C. Second, when the first layer of ply should be chopped fiber mat. D. Hull version with a

18、 two bonding, the bonding on both sides should give full play 100MM hair, bonding thickness of 1.45 times the thickness of the substrate.6. The production of vertical and horizontal ribs1) The end of the hull layer of paste after curing, according to the chart position of pre-formed core material 2

19、vertical and horizontal ribs, and placed in place with resin.2) All longitudinal material together into a whole, does not allow intermediate discontinuity, such as ribs and rib panels with cross, we must first longitudinal rib or ribs materials do. 3) When using foam core material, the perforation i

20、n the bulkhead or water to be set watertight layer, made of wood embedded in the street to pick up wood and other continuity. 4)Vertical and horizontal cross parts are tapered, the glass fiber arrangement and bonding is very difficult, especially not the same height, if they have gaps or pits will b

21、e broken because, should mainly refer to the following:加强层转角加强面层加强7. Embedded parts of the construction1) On outfitting the boat and some ancillary parts for the installation of beautiful and maintain a reliable water tightness, the fastening method commonly used embedded iron or hardwood to solve.2

22、) Arranged according to the requirements of many embedded components, and shall ensure the water tightness of embedded parts, embedded parts of the construction methods shown in Figure:预埋件玻璃钢包覆=2-3玻璃回丝泡沫塑料=15-20玻璃钢外壳8. Boat shell, roof, and most pieces of ply to, the main inspector shall supervise a

23、nd inspect the next operation is completed, it is timely in the "shop floor operating record" signed by the appropriate project acceptance, the vertical and horizontal aggregate, embedded, etc. operation, inspection and must fill out the "hull quality inspection table." 9. FRP mo

24、del 1) Every three months to make the FRP sample.2) The production model is generally set to die on the outer hull extends from 45 ° on the template, such as unconditional in the same plant can be carried out under the same conditions. 3) The dimensions of 500X500, dwarf template should be slig

25、htly larger. 4) Each sample should be marked hull number, date of molding. 5) When necessary, in the presence of ship survey carried out or ship inspection should be specified at any time to increase production model.
