Correct Answer: B) Improved fiber-to-resin ratio, reduced air voids, better control over material properties, and enhanced structural integrity.
- Explanation:
- Improved Fiber-to-Resin Ratio: Resin infusion molding allows for a more controlled application of resin, leading to a better ratio of fiber to resin compared to manual methods.
- Reduced Air Voids: The vacuum process in resin infusion helps to remove air bubbles, resulting in a composite with fewer voids.
- Better Control Over Material Properties: The infusion process provides better control over the distribution and saturation of resin, which can lead to more consistent and predictable material properties.
- Enhanced Structural Integrity: By reducing air voids and achieving a better fiber-to-resin ratio, the final product often has improved strength and durability.
Incorrect Options:
A) Lower material costs, faster production times, and increased risk of voids in the final product.
- Explanation: While resin infusion can offer some cost benefits and faster production times compared to traditional methods, it does not typically increase the risk of voids. In fact, resin infusion aims to reduce air voids, which is an advantage over traditional methods that might have higher void rates.
C) Higher labor costs, longer curing times, and reduced control over material distribution.
- Explanation: Resin infusion molding generally reduces labor costs because it is a more automated process compared to manual methods. It also tends to have shorter curing times due to better control over the resin curing process. The method actually improves control over material distribution, contrary to what is stated here.
D) Increased use of manual labor, higher weight of the final product, and less consistent material quality.
- Explanation: Resin infusion molding is designed to reduce manual labor compared to traditional methods. It also tends to produce lighter and more consistent products due to the efficient resin distribution and reduced air voids. Therefore, this option is incorrect as it does not reflect the advantages of resin infusion molding.
