Composites are made of two or several components assembled in a single structure. Polymer composites are classically prepared with a polymer matrix reinforced by polymer fibres having properties different from the ones of the matrix, searching for a synergy in order to reach composites properties better than the individual components. In most cases, there is a need to improve the adhesion of the two polymers. Many strategies have been used for this, either by chemically or physically treating the reinforcing polymer or adding a coupling agent. An elegant way to avoid having an interface difficulties is to use the same polymer for both the matrix and the reinforcing filler. These composites are called “All polymer composites”. The first work on all cellulose composites was published in 2004. Since then, many papers appeared exploring the various strategies for mixing a cellulose matrix with cellulose fibres or nano-fibres. We are reporting here our attempts to prepare all cellulose acetate composites. One preparation method was tested, a melt route where cellulose acetate fibres are mixed with a molten cellulose acetate matrix. This preparation method produced composites with improved mechanical properties.
