What are the advantages of using resin transfer molding (RTM) in the manufacture of carbon fiber components?
A. Provides high precision and consistency, allows for complex shapes and large parts, reduces labor costs, and enables efficient use of materials.
How is the base raw material turned into usable carbon fiber?
A. The raw material is first spun into fibers, then stabilized through a chemical process, carbonized at high temperatures, and finally treated with a surface finish before being combined with a resin matrix.
How does the internal structure of carbon fiber contribute to its unique strength properties?
A. Carbon fibers have a crystalline structure with carbon atoms arranged in hexagonal lattices, which provides high tensile strength and stiffness.
Which of the following are considered undesirable properties of carbon fiber for mast construction in marine applications?
A. High cost, potential for brittle failure, and high susceptibility to UV degradation.
What is resin transfer molding (RTM) in the manufacture of carbon fiber components?
A. A process where resin is injected into a closed mold containing carbon fiber layers, allowing the resin to saturate the fibers and then cure under pressure to form the final component.
Which properties of carbon fiber make it suitable for hull construction in marine applications?
A. High strength-to-weight ratio, excellent corrosion resistance, low thermal conductivity, and high impact resistance.
Which of the following are considered undesirable properties of carbon fiber for hull construction in marine applications?
A. High cost, high susceptibility to UV degradation, and potential for brittle failure.
Which of the following are four properties of carbon fiber that make it desirable for marine fabrication?
A. High tensile strength, low weight, high stiffness, and excellent resistance to corrosion.
What are the advantages of using vacuum bagging in the manufacture of carbon fiber components?
A. Reduces air bubbles and voids, ensures even resin distribution, improves fiber-to-resin ratio, and helps in achieving a smoother surface finish.
Which properties of carbon fiber make it suitable for mast construction in marine applications?
A. High strength-to-weight ratio, high stiffness, excellent fatigue resistance, and low thermal expansion.
What is autoclave curing in the manufacture of carbon fiber components?
A. A process where carbon fiber components are heated under high pressure in an autoclave to cure the resin, which enhances the composite's strength and durability.
What is vacuum bagging in the manufacture of carbon fiber components?
A. A process where a vacuum is applied to remove air and excess resin from the carbon fiber layup, ensuring a compact and void-free composite.
What are the advantages of using autoclave curing in the manufacture of carbon fiber components?
A. Achieves high-quality curing with uniform temperature and pressure, reduces voids and air bubbles, enhances mechanical properties, and ensures consistent material performance.
How are carbon fibers turned into a usable product?
A. Carbon fibers are first woven into fabric, then impregnated with resin, and finally cured in an autoclave to form a composite material.
Which of the following are necessary safety considerations when working with carbon fiber? (Select all that apply)
A. Wearing personal protective equipment (PPE) such as gloves and masks., B. Ensuring proper ventilation to avoid inhaling dust and fumes., C. Avoiding direct contact with resin chemicals and using appropriate protective measures.
