As a result of manufacturing processes, thermal residual stresses often occur in fibre-reinforced polymer composites and affect the fibre/matrix interface properties, e.g. interfacial shear strength (IFSS), which is commonly evaluated by the microbond test. In thermoplastic matrices, thermal residual stresses can be relieved by annealing. In this study, to examine the effect of thermal residual stress on IFSS, microbond tests on both air-quenched (control) and annealed polyphenylene sulphide/carbon fibre samples are conducted. Comparing the pull-out results of the control to the annealed samples subjected to six different annealing temperatures between 80 and 230°C, it is found that the thermal residual stresses in the fibre axial and radial directions are reduced progressively below and can be neglected above 120°C. Thermal residual stresses in the fibre direction can be calculated to explain the microbond test results and construct a master curve for the IFSS. Postdebond frictional shear stresses can also be analysed in terms of the calculated fibre radial thermal residual stresses and debonded fibre morphologies.

“…The two plates were polished so that there was a sharp blade edge formed along one of the surfaces. Based on the design used by Yang during similar method development [13] a small angle of approximately 1.2 degrees was deliberately designed between these two blades to facilitate sliding of the fibre into the gap. This also ensured the required experimental condition that there was no gap between the fibre and the shearing blades for each fibre, despite the individual variations of fibre diameter from sample to sample.…”

A METHOD TO MEASURE THE INFLUENCE OF HUMIDITY AND TEMPERATURE ON THE INTERFACIAL ADHESION IN POLYAMIDE COMPOSITES AbstractThe work presented focuses on the need to better understand the effect environmental conditions, namely humidity have on the interfacial shear strength (IFSS) of composites. The IFSS was first characterised using the microbond test method in a laboratory atmosphere. A specialised rig was then designed and manufactured in order to carry out the microbond test in a Dynamic Mechanical Analyser with a humidity chamber accessory. Due to the wellknown moisture absorbing nature of polyamide matrices the effect of a range of conditions from 0% to 90% relative humidity were investigated. Results presented for both methods are based on the use of a PA6 matrix. Steel fibres are used extensively for method development and comparison throughout this work. Finally, successful testing on the primary system of fully sized HiPer-Tex™ glass fibre polyamide 6 effectively shows that humidity influences the measured apparent IFSS.

“…In short-fiber composites, the IFSS has been found to either decrease with increasing content of inorganic [14-16, 46, 47] and natural [19][20][21]24] fibers, stay approximately constant, [48,49] and [23,27], respectively, or even increase [42,50] with it. It has been proposed in [51] that the apparent IFSS can be expressed as the sum of two…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. found to be greater for composites with a higher fiber loading and to decrease with increasing content of plasticizer. The IFSS is equal or greater than the yield strength of the neat polymer, suggesting good adhesion, as expected for the chemically compatible constituents.
