What is required when fiberglass laminate damage extends completely through one facing and into the core?

• A. Repair of the exterior layer only
• B. Replacement of the damaged core and facing
• C. Application of an adhesive to bond the layers
• D. Strengthening with additional layers of fiberglass

Answer: (B)

When fiberglass laminate damage extends completely through one facing and into the core, full replacement of the damaged core and facing is necessary. This is crucial because if the core is compromised, it can significantly affect the structural integrity and performance of the laminate, making it inadequate for its intended use. Simply repairing the exterior layer or applying an adhesive would not restore the necessary strength and stability, and strengthening with additional layers would only further obscure the underlying damage without addressing the core's compromised state. Therefore, the comprehensive approach ensures that both the facing and the core are adequately restored to maintain the desired structural properties.
