Water absorption of composite materials causes an expansion (hygroscopic) which may result in an outward force being generated against the cavity walls. The purpose of this work was to investigate the relationship between this force and the water absorption of the material over a 6 month period of water storage. This investigation was performed by measuring the force required to displace specimens of the test materials from near cylindrical cavities. An outward force developed over a period of… CONTINUE READING
