Title: HYGROTHERMAL RESPONSE OF COMPOSITE NANOMATERIAL INTERFACES
Authors: Ana De Leon, Matthew Wadsworth, Zipporah Harlan, Dr. Rebekah Sweat
Abstract: Surface conditioning treatment is severely essential to understanding composite material properties. The interfacial shear strength (IFSS) is the strength of the bond between the matrix phase and the reinforcement phase. The adhesion between the matrix and the fibers is necessary because the mechanical properties of the composite material rely on strong bonding in varied environmental service conditions. However, no current tests demonstrate how humidity and water immersion affect polymer IFSS. This paper presents a fiber matrix pullout test with conditioned samples. Carbon nanotube (CNT) yarns with two temperatures and three time sets are demonstrated during the test. The adhesion strength between reinforcement and matrix is expected to be changed by the temperature and humidity.
