Effects of Novel Structure Bonding Materials on Properties of Aeronautical Acrylic

Blog Article

Novel structure bonding materials, J-351 epoxy adhesive film with low curing temperature gotrax handlebar and liquid modified acrylate SY-50s adhesive were chosen and characterized.The effects of adhesives on the mechanical properties of acrylic were studied.The results reveal that both adhesives have excellent bonding properties to acrylic.The stress-solvent crazing value of J-351 is higher than that of SY-50s.With the application of adhesive on the surface, mechanical properties of acrylic are declined.

Casting acrylic shows more drastic decline than that of oriented acrylic.Through the characterization of fracture surface, we find that fracture of tensile sample derives from the side with adhesive.Mechanical properties of acrylic are more sensitive to SY-50s, because the liquid adhesive presents integrate bonding interface with acrylic.The interface between J-351 and acrylic is click here clear, making acrylic insensitive to J-351 film.Edge attachment strength of samples bonded with J-351 are higher than that of samples bonded with SY-50s due to the effects of adhesives on acrylic.

J-351 epoxy adhesive film presents preferable application performance in the structure bonding of aeronautical acrylic.
