FAQS
What should I do if the resin doesn't cure after the expected time?
This is usually caused by incorrect mixing ratios or temperatures below 5°C.
Solution: Ensure the resin and hardener are weighed accurately according to the TDS. In cold weather, use a specialized low-temperature curing agent or provide external heating to the curing area.
How to handle "hollow sounds" or air bubbles found after the fiber has cured?
Voids (hollow spots) larger than 10mm can compromise the structural integrity.
Solution: For small bubbles, use a syringe to inject impregnating resin into the void. For larger areas, the hollow section must be cut out and replaced with a new fiber patch, ensuring a 100mm overlap on all sides.
Can I apply multiple layers of fiber cloth at once?
No. To ensure full saturation and prevent delamination, fibers should be applied layer by layer.
Solution: Wait for the first layer of resin to reach initial cure (finger-dry) before applying the second layer. Applying multiple layers simultaneously often leads to trapped air and insufficient bonding.
Why is surface grinding so critical for the convex corners?
Carbon and basalt fibers are high-strength but sensitive to sharp bending.
Solution: Sharp edges cause "stress concentration." Grinding corners to a radius (R≥20mm) allows the fiber to wrap smoothly, ensuring it carries the load as designed without premature snapping.
