Project title

Experimental and numerical study of the interphase properties of bio- fibre/lignin-epoxy composites using a micromechanical approach

(Co)tutors

• Tutor: T. Stern (UG)
• Co-Tutor: P. Deuss (RUG)
• Industrial Supervisor: M. Frey (Bcomp)

Objectives

• Characterise the interface region between bio-fibre and lignin-based epoxy resin and map the nonuniform mechanical properties in the interphase material
• Shed light on the physicochemical phenomena that take place in the interface region during plant fibre impregnation and epoxy curing
• Evaluate the influence of non-uniform mechanical properties using micromechanical models and numerical simulation

Required education level

Preferred background

Mechanical Engineering, Materials Science, Polymer Chemistry

Secondments

• ETH (4 months) application of developed characterization methods on wood-based composites (I. Burgert)

• BComp (6 months) investigate and understand requirements for fibre-applications (M. Frey)
