This new thermoplastic composite material comprises a thermoplastic matrix (100 pts.by wt.), hemp fibres (15-110 pts.wt.) homogeneously dispersed in the matrix, and a wood filler (5-65 pts.wt.). The wood filler can be particles, powder or flakes and is dispersed homogeneously in the thermoplastic matrix. The thermoplastic matrix is specified to be one of polypropylene, polyethylene, ethylene-propylene co-polymer, acrylonitrile-butadiene-styrene co-polymer, or nylon (polypropylene is pref.). The thermoplastic composite material can contain 10-40 pts.wt. of inorganic filler such as talc, and can also contain a suitable amt. of plasticiser and/or lubricant. The hemp fibres are specified to be one substance or a combination of two or more substances selected from among ramie, flax, hemp, jute, Manila hemp or sisal hemp. The particles of the composite material are formed into sheets adapted for stamping or pellets adapted for injection moulding. |
