The effect of interface adhesion, water immersion and anatomical notches on the mechanical properties of denture base resins reinforced with continuous high performance polyethylene fibres

Previous work has presented a study of the mechanical properties of denture base resins reinforced with a new type of high performance fibre. It is now shown that the substantial improvements demonstrated in those composites remain largely unaffected by a watery environment, anatomical notches, moulding pressure and other factors of denture construction. The understanding of the reinforced resins is here complemented with a detailed study of the interface strength, taking into account the various couplings occurring within the system.
