Fibers lifted when tearing off process peel ply

Fibers are lifted and damage the surface when tearing off the peel ply (Peel Ply). The interlayer separation phenomenon gradually expands after the product is stressed or subjected to environmental action, seriously affecting structural integrity.

(1) Process factor: adhesion force between peel ply and product too large; this factor affects the '2079851475616104453 and final quality of the product. (2) Process factor: improper tearing angle, applying force perpendicular to the surface; this factor affects the '2079851475616104453 and final quality of the product. (3) Interface aspect: insufficient interlayer bonding, resin impregnation inadequate or already gelled and lost tack. (4) Process aspect: interlayer contamination or insufficient temperature/pressure causing the interface not fully fused. (5) Material aspect: poor surface compatibility between resin and reinforcement material.

(1) Material selection: choose peel ply materials with low adhesion force; establish material selection evaluation standards and determine the optimal solution through comparative tests. (2) Implementation measures: peel at a low angle of 180° along the surface when tearing off; formulate specific operation plans based on actual production conditions and verify implementation effects. (3) Formulation adjustment: ensure full resin curing to reduce adhesion., adjust gradually and verify the effect, ensuring that other performance indicators of the product are not affected. (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.
