The applicability of two different biobased thermoset resins was evaluated. The first resin is based on soybean oil and the second on lactic acid. Both resins are cross-linkable and produced from renewable resources. Prepregs were manufactured from the two resins together with natural fibres (flax and cellulose). Furthermore, sheet moulding compound (SMC) was developed from lactic acid based resin together with glass fibre. Seat shells were produced from the prepregs by compression moulding. Curing of the composites was monitored using a response surface methodology. Further, the fibre ratio, mechanical properties as well as adhesion between the matrix and the fibre were evaluated. These prepregs offers short cycle times and yield products with suitable mechanical properties. Issues related to the preparation and the processing of the prepregs are discussed in the article.
