Abstract

The adhesion between reinforcing fibres and matrix material is crucial for the performance of composite structures. In this study we treated foam formed cellulose fibre sheets with plasma and atomic layer deposition (ALD) treatments to achieve better adhesion between cellulose fibres and epoxy matrix. Plasma treatment was done using 8 kW and 12 kW outputs and ALD cycles with Ti2O and Al2O3. Surface treated foam formed sheets were laminated into composite structure with epoxy resin using vacuum assisted resin infusion. Complete laminated composites were water jet cut and interlaminar shear strength was measured. Effect of plasma treatment to adhesion was minimal and ALD treatment had minimal or no effect at all. Reason for low ILSS values can be explained with high void content of samples caused by processing aids in foam forming process.
