method of making natural wood polymer composite

composites reinforced with cellulose based fibres - sciencedirect

the application of natural fibres as reinforcements in composite materials requires just as for glass-fibre reinforced composites a strong adhesion between the fibre and the matrix regardless of whether a traditional polymer (thermoplastics or thermosets) matrix a biodegradable polymer matrix or cement is used.【Get Price】

wood plastic composites - a primer

wood plastic composites (wpcs) are roughly 50:50 mixtures of thermoplastic polymers and small wood particles. the wood and thermoplastics are usually compounded above the melting temperature of the thermoplastic polymers and then further pro-cessed to make various wpc prod-ucts. wpc can be manufactured in a variety of colors shapes and【Get Price】
