“…PA6 has one of the highest rates of moisture absorption and it has been extensively reported by Thomason et al. that the mechanical properties of similar polyamides and resulting composites they are used in, are markedly decreased upon moisture absorption [8][9][10][11][12].…”

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.

“…Nylon 6,6, the strongest and most abrasive resistant unreinforced nylon, has been used for such biological applications as sutures, tracheal tubes and gastrointestinal segments [20]. With regards to orthopedic applications it can be seen that nylon is not commonly employed due to the hygroscopic nature having a large affect on the mechanical properties over long periods of time [21]. Having said that, the use of nylon 6,6 within this work gives high value experimentally insofar as to ascertain generic factors for polymeric materials which could be used to predict the osteoblast cell response.…”

1522 668891 -AbstractWith an ageing population the demand for cheap, efficient implants is ever increasing. Laser surface treatment offers a unique means of varying biomimetic properties to determine generic parameters to predict cell responses. This paper details how a KrF excimer laser can be employed for both laser-induced patterning and whole area irradiative processing to modulate the wettability characteristics and osteoblast cell response following 24 hour and 4 day incubation. Through white light interferometry (WLI) it was found that the surface roughness had considerably increased by up to 1.5 µm for the laser-induced patterned samples and remained somewhat constant at around 0.1 µm for the whole area irradiative processed samples. A sessile drop device determined that the wettability characteristics differed between the surface treatments. For the patterned samples the contact angle, θ, increased by up to 25° which can be attributed to a mixed-state wetting regime.For the whole area irradiative processed samples θ decreased owed to an increase in polar component, γ P . For all samples θ was a decreasing function of the surface energy. The laser whole area irradiative processed samples gave rise to a distinct correlative trend between the cell response, θ and γ P . However, no strong relationship was determined for the laser-induced patterned samples due to the mixed-state wetting regime. As a result, owed to the relationships and evidence of cell differentiation one can deduce that laser whole area irradiative processing is an attractive technology for employment within regenerative medicine to meet the demands of an ageing population.Keywords: Excimer laser, nylon 6,6, wettability, osteoblast cells, bioactivity, regenerative medicine. -IntroductionIt has been realized worldwide within the scientific community and various industries that lasers offer major advantages over alternative techniques for materials processing [1][2][3][4]. Some of the main advantages of using a laser for materials processing are:• Relative cleanliness.• Accurate processing.o Allows much control over the Heat Affected Zone (HAZ) due to the ability of relative precise control over the thermal profile and thermal penetration/absorption.• Precise placement of the beam onto the target material allowing user specified areas of the target material to be processed.• Post-processing techniques required are usually minimal.• Non-contact processing.• Automation (repeatability) of the various processing techniques using a laser is relatively easy to implement.With a large number of different lasers now commercially available it is possible for one to deduce that almost all materials can be processed using a laser due to the wide range of laser parameters that can be utilized. With the many benefits of using lasers for materials processing it has been found that the interest in laser-induced surface treatment has grown, especially within the biomedical industry. This is due to the fact that lasers offer the user a highly selective, rapid...
