Mechanical properties of corona‐modified cellulose/polyethylene composites

Abstract

The effect of corona treating the surfaces of components on tensile properties of wood fiber linear low-density polyethylene composites has been investigated. Corona treatment results in a significant increase in strength properties of the composites. Yield stress increases after treatment of one or both of the composite components. Pronounced improvement in ductility has been observed for composites containing 15 to 30% of the corona modified fiber. Relevant mechanisms involved are discussed.

Influence of MA-g-PP on abrasive wear behaviour of chopped sisal fibre reinforced polypropylene composites

“…They found improved interfacial adhesion between cellulose fibres and PP. Dong et al (1993) have also recently reported the matrix modification in jute/PP composites on the addition of MAg-PP. There is no report available in the literature on the effect of MA-g-PP on the abrasive wear properties of sisal fibre reinforced PP composite.…”

Influence of modified wood fibers on the mechanical properties of wood fiber-reinforced polyethylene

“…composites is the poor interfacial adhesion between the hydrophobic polymer matrix and the EXPERIMENTAL hydrophilic wood fiber. These can be solved by chemical modification of the wood fiber surMaterials face, [4][5][6][7] e.g., grafting a short-chain molecule onto Linear low-density polyethylene (LLDPE, melt index: 5.0 g/10 min; density: 0.930 g/cc) was sup- at the peak point. The tensile modulus was calculated at 0.1% of elongation.…”

How to decrease the hydrophilicity of wood flour to process efficient composite materials

“…With the aim of changing the surface chemistry of the wood filler and of making it more compatible with the polymer, several chemical treatments may be used such as esterification [11][12][13][14][15] and reaction with alkaline solutions [9,[16][17][18]. Physical and thermal treatments were also performed [10,[19][20][21] such as curing [22] or corona discharge [23][24][25].…”
