Comparison of Tensile Strength and Fracture Toughness of Co-Bonded and Cold-Bonded Carbon Fiber Laminate-Aluminum Adhesive Joints.

The purpose of this work is to compare the co-bonding vs. cold-bonding route on the adhesive joint performance of a CFRP (Carbon Fiber Reinforced Polymer) laminate-aluminum connection. In particular, the overlap shear, tensile strength and Mode I and Mode II fracture toughness will be evaluated.

Conceptual Study and Manufacturing of a Configurable and Weld-Free Lattice Base for Automatic Food Machines.

The study is aimed at developing a modular lattice base for automatic food machines, starting with a solution already patented by some of the authors. In this case, welded carpentry modules were interlocked with a system of profiles and metal inserts, also in welded carpentry, and the union was stabilized by structural adhesive bonding. Since welding involves long processing times and thermal distortions to be restored later, the driver of this study is to limit the use of welding as much as possible while increasing the modularity of the construction.

Optimal Design of Shape Memory Alloy Compositeunder Deflection Constraint.

Shape-adaptive or morphing capability in both aerospace structures and wind turbineblade design is regarded as significant to increase aerodynamic performance and simplifymechanisms by reducing the number of moving parts. The underlying bistable behavior ofasymmetric cross-ply composites makes them a suitable candidate for morphing applications. Todate, various theoretical and experiential studies have been carried out to understand and predictthe bistable behavior of asymmetric laminates and especially the curvature obtained in their stableconfigurations.

Improvement of a Cohesive Zone Model for Fatigue Delamination Rate Simulation.

The cohesive zone model (CZM) has found wide acceptance as a tool for the simulation of delamination in composites and debonding in bonded joints and various implementations of the cohesive zone model dedicated to fatigue problems have been proposed in the past decade. In previous works, the authors have developed a model based on cohesive zone to simulate the propagation of fatigue defects where damage acts on cohesive stiffness, with an initial (undamaged) stiffness representative of that of the entire thickness of an adhesive layer. In the case of a stiffness that is order of magnitude higher than the previous one (for instance, in the simulation of the ply-to-ply interface in composites), the model prediction becomes inaccurate.

Screening of sensitivity to mandipropamid of Plasmopara viticola populations from Italian vineyards by molecular and biological methods.

Unlabelled: The objective of this work was to study the sensitivity to mandipropamid of 33 Plasmopara viticola populations utilizing both molecular and biological techniques. The PCR-RFLP technique was developed in order to detect the single point mutation, G1105S, occurring on the PvCesA3 gene. The sensitivity was also studied using the leaf-disc bioassay.
