Mechanical bonding and physical adsorption oil paper bag production

With infiltration theory to explain the interfacial bonding mechanism has two modes: mechanical bonding and physical adsorption.

Mechanical bonding mode after that the polymer (liquid resin) wetting the fibers, that is, into the fiber pores and uneven depressions among the T-type mechanical binding when the resin is cured after formation.

Physical adsorption mode is that such infiltration is the essence of resin and fiber surface physical adsorption occurred van der Waals forces. This binding leads to force Composite Interface.

Infiltration theory explains the fiber surface roughening, increasing the surface area and conducive community! (Binding facts. Such as carbon fiber oxidation in air at 870 ℃, an increase of irregularities vary significantly increased the level of its thermosetting resin composite material between shear strength with nitric acid treatment, to improve carbon fiber epoxy resin infiltration, reducing the wetting angle, increasing the surface area and improve the interlaminar shear strength of the composite material.
