Interlayer peeling/delamination (debonding)

Insufficient bonding force between layers of laminated products, causing separation. The interlayer separation phenomenon gradually expands after the product is stressed or subjected to environmental action, seriously affecting structural integrity.

(1) Process factor: insufficient resin impregnation of reinforcement material or resin content too low; this factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: interlayer resin has begun to gel and lost tack before hot pressing; this factor affects the '2079851475616104453 and final quality of the product. (3) Process factor: interlayer contamination; this factor affects the '2079851475616104453 and final quality of the product.

(1) Formulation optimization: increase resin content to ensure full impregnation; determine the optimal addition amount through small-batch tests, and verify the impact on the comprehensive performance of the product. (2) Process control: control layup stacking speed to complete within the pot life of the resin; establish an online monitoring mechanism, set parameter upper and lower limits and implement alarm management. (3) Operation specification: keep the working environment and materials clean., formulate standard operating instructions for cleaning operations and perform inspections before each production. (4) Preventive measures: establish interlayer bonding strength testing standards, regularly sample interlayer shear strength, and monitor process parameter stability.

The essence of interlayer separation problems is insufficient interface bonding force, requiring systematic improvement from three aspects: impregnation quality, interlayer cleanliness, and process parameters.
