Flexibility Unlike brittle fibres, lignocellulosic fibres will not be fractured during processing. [Pg.405]

Extrusion and injection-moulding are the economically most attractive processing methods of thermoplastic-based composites. The extrusion press processing (express-processing) has been developed for the production of flax fibre reinforced PP at the research centre of Daimler Benz [7]. In this process, flax fibre non-wovens and PP melt films are alternatively deposited and moulded. A production process for PP semi-products reinforced with lignocellulosic fibres in the form of mats has been developed by BASF AG [7]. Fibre mats are produced by stitching together layers of fibres which have previously been crushed. [Pg.406]

Fibre surface modification. The surface energy is closely related to the hydrophilicity of the UgnoceUulosic fibres. Use of dispersing agents, such as stearic acid or a mineral oil. The dispersion of lignocellulosic fibres can be improved by pretreatment with lubricants or thermoplastic polymers. An addition of 1-3 per cent stearic acid is sufficient to achieve a maximum reduction in size and number of aggregates in PP and polyethylene [7]. The use of stearic acid in HDPE/wood fibres was reported to improve the fibre dispersion and the wetting between the fibre and the matrix [9]. [Pg.409]

As already maitioned, the surface modification of lignocellulosic fibres is comprehensively dealt with in Chapter 18. [Pg.409]

Chapter 8 concentrates on sustainable construction. Wood-plastic composites are being used in construction at an increasing rate. Lignocellulosic fibres and plastic composites are extensively discussed in Chapter 10. [Pg.2]

The application of lignocellulosic fibres in reinforcing plastics has been known for a long time. As early as 1908 the first composite materials were applied for the production of large quantities of sheets, tubes and pipes for electronic purposes (paper or cotton to reinforce sheets, made of phenol or melamine formaldehyde resins). In 1896, aeroplane seats and fuel tanks were made of natural fibres with a small amount of polymeric binder [1],... [Pg.349]

Because of low prices and the steadily rising performance of technical and standard plastics, the application of natural fibres for obtaining lignocellulosic fibre - plastic composites is widely used. More recently, the critical discussion about the preservation of natural resources and recycling has led to a renewed interest concerning natural materials with the focus on renewable raw materials [2],... [Pg.349]
