Glass fiber paving operation

Glass fiber paving operation

A release agent, usually in wax or liquid form, is applied to the selected mold to allow clean removal of the final product from the mold. The resin (usually a two-part thermosetting polyester, vinyl or epoxy) is mixed with its hardener and applied to the surface. Put the glass fiber felt sheet into the mold, and then use a brush or roller to add more resin mixture. The material must be consistent with the mold, and air must not be trapped between the glass fiber and the mold. Other resins are applied, and possibly glass fiber boards are added. Use manual pressure, vacuum or rollers to ensure that the resin is saturated and fully wets all layers, and removes all air pockets. Unless a high-temperature resin is used, the high temperature must be carried out quickly before the resin starts to cure, unless the high-temperature resin can only be cured by heating the part in an oven. In some cases, the workpiece is covered with a plastic sheet, and a vacuum is applied to the workpiece to remove air bubbles and press the glass fiber into the shape of the mold.

Glass fiber spray coating equipment operation

The glass fiber spray layup process is similar to the manual layup process, but the application of fiber and resin on the mold is different. Spraying is a manufacturing process of open-molded composite materials in which resin and reinforcement are sprayed onto the mold. Resin and glass can be used separately, or they can be "shredded" from the spray gun of the shredder at the same time. Workers sprayed spray to compact the laminate. Then you can add wood, foam or other core material, and a second spray layer embeds the core material between the laminates. The part is then solidified, cooled and removed from the reusable mold.
