Glass Fibre surface microcracks
Fenómeno do problema
Glass Fibre product surface shows 0.05-0.2mm microcracks, affecting appearance and strength
Análise das causas
Glass Fibre product internal stress too large, exceeding material yield stress; environmental stress cracking; product design stress concentration
Solução
1) Annealing treatment to release internal stress; 2) product design avoids sharp corners and stress concentration; 3) select high molecular weight Glass Fibre to improve crack resistance
Conclusão principal
Microcracks are caused by excessive internal stress; annealing and crack-resistant design are key
