▼ The depletion of petroleum feedstock along with significant concerns about health and environment lead to an interest in alternative green products. Soy protein (SP) adhesives have great potential as a renewable material for wood industries. The obstacle of applying SP-based adhesives is its relatively low water resistance. The overall objective was to enhance the water resistance of SP adhesives through protein and lignin interaction. An improvement of adhesion performance, flowability, and thermal properties of SP adhesives was achieved through the protein and lignin interaction and formation of protein and lignin copolymer. pH adjustment is a simple process to change protein folding and lignin properties. Cleavage of β-O-4 linkage was observed at pH 8.5 and pH 12, resulting in an increase in lignin active groups and the changes in lignin particle size and thermal properties. Cross-linking of protein with lignin took place via carbonyl, amino, and hydroxyl groups. Multiple-point and non-specific interactions between lignin and protein resulted in stronger lignin-protein networks and changes in properties, which improved wet adhesion strength of protein adhesives. In addition, lignin was depolymerized by laccase enzyme with the presence of mediator, TEMPO, to induce a formation of the strong lignin-protein network. The formation of the strong lignin-protein network increased the wet adhesion strength by 106% and the partial wood failure was observed after the three-layer wood test. A better performance was also observed on the three-cycle soaking test. The adhesion performance of SP adhesives was also greatly affected by lignin particle size and the protein to lignin ratio at pH 4.5. The wet adhesion strength of SP adhesives increased as lignin particle size decreased. The protein-lignin adhesive with protein to lignin ratio of 10:2 (w/w) at 12% solid content had the lowest contact angle and the highest wet adhesion strength of 4.66 MPa, which is 53.3% higher than that of 10% pure SP adhesive. Lignin-protein interactions, water resistance property, and glue line pattern had strong influences on an adhesion performance. Lignin and soy protein were modified at pH 4.5, 8.5 and 12. The maximum increase (620%) in water resistance was found at pH 12 with an addition of lignin. After the protein was unfolded (pH 8.5) and denatured (pH 12), it was refolded by shifting pH to 4.5. The better-wet adhesion performance was obtained at pH 4.5, 8.5-4.5 and 12 with rigid glue line. Shifting pH from 8.5 to 4.5 promoted lignin-protein interaction and increased adhesion performance. The protein-lignin adhesives using absolutely renewable materials and practical processes showed an excellent potential to replace the petroleum-based adhesives and fulfill the global demand for green products and technologies.

▼ Fiber reinforced polymer (FRP) composites have been used widely in the land transportation, aerospace, marine structures and characteristically conservative infrastructure construction industries and generally, the interface plays very important role in the properties of FRP materials. Therefore, this research studied the mechanical and interfacial property involved in the non-weld samples, weld samples and adhesive samples of insert moldings. Green composites as one of environment-friendly materials are becoming more and more attractive. The control of environmental pollution, the high performance properties and the recycling opportunity make thermoplastic polymers very attractive. The combination of thermoplastics and renewable natural fibers such as jute fibers as reinforcement in composites will answer the demand of environmental friendly materials. Jute fibers have several specific advantages including low cost, high and comparable specific mechanical properties, excellent biodegradability, and good thermal and acoustic insulation. On the other hand, due to the good biodegradability and good recyclability, mechanical properties and light weight, polylactic acid (PLA) and polypropylene (PP) has been widely used in many aspects, such as automotive parts and house furnishings. Injection molding is one of the most attractive mass production methods for plastic parts in industry owing to its high production rate, short cycle times and low percentage of scrap, available and versatile moulds. However, weld line is one of the typical problems seen in injection molding. The presence of weld lines not only detracts from the surface quality but also significantly reduces the mechanical strength of injection-molded parts. In this research, firstly it studied the mechanical properties of injection molded jute/PLA and jute/PP with or without weld line. The Kelly-Tyson model was used to estimate the interfacial property of injection molded jute/PLA and jute/PP with or without weld line. The method of increasing-holding pressure and re-compounding technology were used to improve the mechanical and interfacial property of injection molded jute/PLA and jute/PP with or without weld line. Glass reinforced polypropylene (GF/PP) composites are the most widely used fiber reinforced thermoplastic because of their excellent mechanical property, good processability and low cost. Many research works have been carried out to investigate the interfacial shear property in the FRP composites, but very few reports on interfacial tension property in FRP materials can be found. As a subsequence, a novel method was established to evaluate the interfacial tension property in the injection molded GF/PP composites based on the characteristic of fiber orientation in the weld samples. In addition, the effect of weld line and scratch on the impact property of injection molded PP and polycarbonate (PC) plate was investigated based on the drop impact test and fracture surface observation. In order to short-cut the production processing and reduce energy…

Le travail présenté dans ce mémoire avait pour objectif d’étudier le processus de la pénétration d'eau dans les composites en carbone/époxyde dans un premier temps, et dans un deuxième temps, d’étudier l’effet de la prise en eau par ces matériaux sur les performances mécaniques des composites et leur joints collés. L'intégration de ces phénomènes physiques dans la modélisation numérique est d'une grande importance dans la prédiction de la durabilité d’une structure en composite subissant un vieillissement hygrothermique. Par conséquent, ce travail consiste non seulement en des observations expérimentales, mais aussi en des simulations numériques. Des corrélations entre les résultats obtenus permettent d’une part de mieux comprendre ce qui se passe dans un système composite avec l’assemblage collé soumis à des charges mécaniques, de l’initiation d’endommagement jusqu’à la rupture finale ; d'autre part, de valider un modèle numérique robuste dans le but de la conception et de l’optimisation. Les originalités de ce travail se situent à différents niveaux en proposant : 1. un nouveau modèle de diffusion à deux-phases permettant de mieux décrire l’effet de l’épaisseur des stratifiés sur la pénétration de l’eau; 2. un nouveau modèle RPM « Residual Property Model » afin de prévoir la dégradation des propriétés mécaniques due à la prise en eau ; 3. une nouvelle loi de traction-séparation linéaire-exponentiel pour décrire la courbe-R observée dans les essais DCB en mode I pur sur les composites stratifiés afin de les intégrer plus facilement dans les modèles numériques
