Modulating impact resistance of flax epoxy composites with thermoplastic interfacial toughening

چکیده
The application of natural flax fibre/epoxy composites is growing in the automotive sector due to their good stiffness and damping properties. However, impact damage resistance flax/epoxy limited brittle nature both epoxy fibres strong fibre/matrix adhesion. Here, biobased thermoplastic cellulose acetate (CA) deployed as a fibre treatment alter development subjected low-velocity impact. perforation threshold energy unmodified cross-ply increased respectively by 66% 42% with CA-treated fibres. CA-modification modestly decreased transverse tensile strength in-plane shear composites. it altered laminates quasi-static tests into ductile failure clearly fibre–matrix debonding.

Overview of Flax Fiber Reinforced Thermoplastic Composites
Flax fibres are oftenly used for reinforcing thermoplastic to manufacture biocomposite materials exhibiting numerous advantages such as high mechanical properties, low density and biodegradability. The mechanical properties of a biocomposite material depends on the nature and orientation of the fibres, the nature of the matrix and mainly on the adhesion between fiber and the polymer matrix. The...
متن کاملProperties and performance of flax yarn/ thermoplastic polyester composites
Aiming at demonstrating the potential of unidirectional natural fiber-reinforced thermoplastic composites in structural applications, textile flax yarn/thermoplastic polyester composites with variable fiber volume fractions have been manufactured by a filament-winding process followed by a vacuum-assisted compression molding process. The microstructure of the composites shows that the flax fibe...
متن کاملThermoplastic starch/wood composites: interfacial interactions and functional properties.
Thermoplastic starch (TPS)/wood composites were prepared from starch plasticized with 36 wt% glycerol. The components were homogenized by dry-blending, extruded and injection molded to tensile bars. Tensile properties, structure, deformation, water adsorption and shrinkage were determined as a function of wood content, which changed between 0 and 40 vol% in 7 steps. The modification of TPS with...
متن کاملToughening of epoxy matrices with reduced single-walled carbon nanotubes.
Reduced single-walled carbon nanotubes (r-SWCNT) are shown to react readily at room temperature under inert atmosphere conditions with epoxide moieties, such as those in triglycidyl p-amino phenol (TGAP), to produce a soft covalently bonded interface around the SWCNT. The soft interface is compatible with the SWCNT-free cross-linked cured matrix and acts as a toughener for the composite. Incorp...
متن کاملToughening Epoxy Adhesives to Meet Today’s Challenges
There are many advantages that polymeric adhesives can offer compared to the more traditional methods of joining such as bolting, brazing, welding, mechanical fasteners, etc. and epoxy adhesives represent the most common type of structural adhesive. When polymerised, epoxy adhesives are amorphous and highly-crosslinked materials and this microstructure results in many useful properties for stru...
