Top 10 Questions for Fiberglasser Interview

1. What is the most important thing to consider when choosing a fiberglass resin?

The most important thing to consider when choosing a fiberglass resin is the intended use of the finished product. Different resins have different properties, such as strength, flexibility, and resistance to chemicals and UV radiation. It is important to choose a resin that is well-suited for the specific project.

2. What are the different types of fiberglass cloth?

Woven cloth

• Plain weave: The most common type of weave, offering a good balance of strength and flexibility.
• Twill weave: A stronger and more flexible weave than plain weave, but also more expensive.

Non-woven cloth

• Chopped strand mat: Made from randomly oriented fibers, offering good strength and impact resistance.
• Continuous strand mat: Made from long, parallel fibers, offering very high strength.

3. What is the difference between a catalyzed resin and a non-catalyzed resin?

A catalyzed resin is a resin that has been mixed with a catalyst, which is a chemical that speeds up the curing process. A non-catalyzed resin is a resin that has not been mixed with a catalyst. Catalyzed resins cure more quickly than non-catalyzed resins, but they also have a shorter working time.

4. What are the steps involved in laminating fiberglass?

• Prepare the surface to be laminated.
• Apply a layer of catalyzed resin to the surface.
• Apply a layer of fiberglass cloth.
• Repeat steps 2 and 3 until the desired thickness is achieved.
• Cure the laminate at the appropriate temperature and humidity.

5. What are the most common problems that can occur during fiberglass lamination?

• Air bubbles: Air bubbles can cause the laminate to be weak and can also create a breeding ground for bacteria.
• Resin starvation: Resin starvation occurs when there is not enough resin to wet out the fiberglass cloth, which can result in a weak and brittle laminate.
• Curing problems: Curing problems can occur if the laminate is not cured at the appropriate temperature and humidity, which can result in a laminate that is not fully cured and is weak.

6. What are the different types of fiberglass finishes?

• Gel coat: A high-gloss finish that is applied to the surface of the laminate.
• Topcoat: A less glossy finish that is applied to the surface of the laminate to protect it from UV radiation.
• Paint: A variety of paints can be applied to the surface of the laminate to provide a desired color or finish.

7. What are the safety precautions that should be taken when working with fiberglass?

• Wear a respirator when working with fiberglass dust or fumes.
• Wear gloves and eye protection when handling fiberglass.
• Do not smoke or eat while working with fiberglass.
• Work in a well-ventilated area.
• Clean up all fiberglass dust and debris after finishing work.

8. What are the different types of fiberglass applications?

• Automotive: Fiberglass is used in the production of car bodies, hoods, and other parts.
• Marine: Fiberglass is used in the construction of boats, kayaks, and other watercraft.
• Aerospace: Fiberglass is used in the production of aircraft components, such as fairings and wings.
• Construction: Fiberglass is used in the production of roofing, siding, and other building materials.
• Medical: Fiberglass is used in the production of medical devices, such as casts and prosthetics.

9. What are the advantages of using fiberglass?

• Strength: Fiberglass is a very strong and durable material.
• Lightweight: Fiberglass is a very lightweight material, making it easy to handle and transport.
• Corrosion resistance: Fiberglass is resistant to corrosion, making it ideal for use in applications where it will be exposed to moisture or chemicals.
• Versatility: Fiberglass can be molded into a variety of shapes and sizes, making it suitable for a wide range of applications.

10. What are the disadvantages of using fiberglass?

• Cost: Fiberglass can be more expensive than other materials, such as wood or metal.
• Brittle: Fiberglass is a brittle material, which means it can be easily broken if it is not handled carefully.
• Combustible: Fiberglass is a combustible material, which means it can burn if it is exposed to fire.

Fiberglassers are skilled craftsmen who work with fiberglass materials to create a variety of products, including boats, automotive parts, and wind turbine blades. They use a variety of techniques to shape and reinforce fiberglass, including hand lay-up, spray-up, and vacuum bagging.

1. Prepare surfaces for fiberglass application

This includes cleaning, sanding, and applying a release agent.

2. Cut and shape fiberglass materials

Fiberglassers use a variety of tools to cut and shape fiberglass, including scissors, knives, and saws.

3. Apply fiberglass to surfaces

Fiberglassers use a variety of techniques to apply fiberglass to surfaces, including hand lay-up, spray-up, and vacuum bagging.

4. Cure fiberglass

Fiberglassers use a variety of methods to cure fiberglass, including heat, pressure, and vacuum.

5. Inspect and finish fiberglass products

Fiberglassers inspect fiberglass products for defects and finish them by sanding, buffing, and painting.
