Comparisons of processing and strength properties of two adhesive systems for composite joints

摘要: Abstract In the present study rheological, static and impact tests are carried out on two adhesive resins usually employed in marine applications; then single lap joint conducted composites joints evidencing effect of curing time both mechanical properties joint. The applicability workability conditions determined evaluating evolution by a preliminary rheological analysis; relation with performances themselves ones composite is estimated. Static flexural Izod performed at increasing after specimen production (curing time); also resistance adhesives studied as well stabilisation long times. Moreover relationship between different failure mechanisms, observed for joints, reaction observed. A numerical model test developed: simple versatile analysis (FEA software ANSYS) elastic regime. Such should be suitable designing and/or verifying shear, axial peel stress trends overlap length.
