Article
Full-text available
Different classes of wastes, namely wooden wastes, plastic fractions from automotive shredded residues, and glass fiber reinforced composite wastes obtained from dismantled wind turbines blades were analyzed in view of their possible recycling. Wooden wastes included municipal bulky wastes, construction and demolition wastes, and furniture wastes....

Laminates were produced with epoxy resins from waste vegetable oil (WVO) intended for the manufacturing of environmentally-friendly alternatives for the composites industry. Post-use cooking oil appears a promising source of triglycerides for polymer manufacturing. Matrices cured with methylhexahydrophthalic anhydride (MHHPA) were reinforced with g...
Conference Paper
Full-text available
Recycled carbon fibres (rCF) can be combined with thermoplastic filaments such as polypropylene (PP) to produce a cost-effective nonwoven hybrid textile for hot stamp forming. Different processing methods have been evaluated to investigate potential industrial applications. Short cycle times and fully impregnated composites were targeted for the ma...
Conference Paper
Full-text available
Environmental concerns motivate researchers to look for more sustainable replacements for epoxy resins to improve the sustainability of recycled carbon fibre composites. Thermoset formulations using bio-based resins from waste vegetable oil (WVO) were investigated. Valorisation of this feedstock brings environmental, social and economic benefits to...
Article
Full-text available
Bio-based thermoset polymers were produced from epoxidized waste vegetable oils cured with anhydrides at different molar ratios. Properties were compared to analogues produced with neat oil and DGEBA as a feedstock. Thermal stability proved to be affected by the molar ratio, and the use of feedstock from waste oil resulted in no effect on this prop...

Aiming to manufacture biomaterials using renewable resources we prepared, using a corotating and intermeshing twin-screw extruder, high-density green polyethylene composites reinforced with 20, 30, and 40 wt % of bleached cellulose fibers. Injection molded test samples are characterized for mechanical and thermal properties using thermogravimetry (...
Article
Thermosets and composites were prepared from blends of epoxidized waste vegetable oils and diglycidylether of bisphenol-A to investigate this material as an alternative triglyceride source for epoxy resins. Purification of the waste oil was developed to remove impurities derived from thermal degradation in the frying process and different epoxidati...

The mechanical properties and stability of cellulose-fiber-reinforced polyamide-6 can be improved by carefully controlling processing prop- erties, employing a lubricant, and using high-lignin-content fibers.
Article
We prepared polyamide-6 (PA-6) composites using bleached and semibleached cellulose fibers from Eucalyptus species by processing in a corotating interpenetrating twin-screw extruder. PA-6 is a challenging matrix because of its high processing temperature, which overlaps the thermodegradation temperature of the fibers. The selection of the processin...

We investigated the structural and thermal properties of a gel polymer electrolyte prepared with poly(ethylene oxide-co-2-(2-methoxyethoxy)ethyl glycidyl ether) (P(EO/EM) matrix, γ-butyrolactone (GBL), and LiI/I2. Nuclear magnetic resonance spectroscopy measurements were carried out in different temperatures for the aforementioned electrolyte compo...
Conference Paper
Full-text available
This work presents the development of natural fiber reinforced composites using polyamide-6 as matrix and bleached or semi-bleached cellulose fibers as reinforcing agents. The challenge was the processing temperature, which had to be adjusted to avoid fiber thermodegradation. The use of ethylene bis(stearamide) as lubricant permitted lowering the p...

My doctoral studies concern the investigation of alternative and eco-friendly sources for green composites structures based on epoxidized resins from chemically modified vegetable oils. The studies range from the initial purification of the alternative sources of vegetable oils to the final application of the bio-based resin to produce thermoset polymers with remarkable bio-content.
