2. The role of bondline thickness on mechanical properties of bio-based polyurethane
ABSTRACT Bio-based adhesives have been largely applied on several applications in many industrial areas, including automotive and laminated food packaging. Polyurethanes (PU) occupy a leading position among the most used bio-based polymers due to their large range of properties and application versatility. Recent works reported that PU obtained from castor o

3. Water Diffusion in Double Cantilever Beam Adhesive Joints
Abstract Structural adhesives are increasingly being used in the aerospace and automotive industries. They allow for light weight vehicles, fuel savings and reduced emissions. However, the environmental degradation of adhesive joints is a major setback in its wide implementation. Moisture degradation of adhesive joints includes plasticization, attacking of t

4. Revestimentos de alta camada obtidos com a modificação de resinas epóxi novolaca pela reação com organo-siloxano e catálise ácida
Epoxy resins are an important class of thermostable polymers, widely used in structural applications or as adhesives. However, the low fracture resistance is their main weakness in many applications. Due to this fact, this study aims to modify a polymer matrix based on a novolac epoxy resin with an organo siloxane (AMS). The final properties of cured epoxys

5. An experimental investigation of static load capacity of AL-GFRP adhesively bonded single lap and double butt lap joints
AbstractThis paper is focused on experimental evaluation and comparison of progressive damage behaviors in adhesively bonded single lap and double butt lap joints between aluminum and glass fiber reinforced plastic (GFRP). The effect of joint design and dissimilarity of adherents on damage evolution of adhesive bonding under tensile quasi static loading is a

6. Physical and mechanical properties of particleboard bamboo waste bonded with urea formaldehyde and castor oil based adhesive
This study evaluated the physical and mechanical characteristics of particleboards made of bamboo waste from the species Dendrocalamus giganteus bonded with two different types of adhesives: urea-formaldehyde (UF) and a castor oil based adhesive (M). Thus, eight types of particleboards were produced in the proportions of 6%, 8%, 10% and 12% for each adhesiv

8. Polyurethane structural adhesives applied in automotive composite joints
In recent years structural adhesives technology has demonstrated great potential for application due to its capacity to transform complex structures into solid unitary and monolithic assemblies using different materials. Thus, seams or joints integrate these structures providing, besides a reduction in weight, a considerable increase in the mechanical resist

9. Adesivos estruturais uretânicos aplicados a combinações de compósitos, plásticos e metais / Structural urethane adhesives applied in combination of composites, plastics and metals
Neste trabalho foram avaliadas as propriedades de um adesivo estrutural uretânico que visavam colagens de peças automotivas compostas por combinações de compósitos, termoplásticos e metais, que requerem do adesivo um elevado desempenho e compatibilidade com esses materiais. Para tanto, foram avaliadas as resistências ao cisalhamento de juntas formadas

10. Studies and applications of glued-in steel rods on shear connectors in mixed wood-concrete deck bridges / Estudos e aplicações de barras de aço coladas, como conectores em lajes mistas de madeira e concreto para tabuleiros de pontes
As pontes tradicionais de madeira no Brasil, nem sempre atingem as condições plenamente satisfatórias em estradas vicinais, exigem manutenção contínua e a maioria não está adequada ao tráfego pesado usual. As pontes mistas de madeira e concreto destacam-se como alternativa econômica apresenta grande resistência e rigidez além de exigir baixa manu
