This paper presents an experimental study on the effect of interfacial fibre orientation and interleaved thermoplastic veil Mode II interlaminar fracture toughness 5-harness satin woven carbon reinforced polymer composite laminates. Three-point End-Notched Flexure tests were carried out to determine delamination resistance, GIIC, specimens with five biases two densities at midplane. Results sho...

This paper presents an experimental testing of two short-fiber reinforced composites (SFRC). The materials are a polyphthalamide with 33% glass fiber inclusion (PPA-GF33) and polyphenylene sulfide 40% inclusion. Rectangular plates were obtained from these by injection molding. Specimens, type 1BA, according to ISO 527-2, cut out orientations 0°, 15°, 30°, 45°, 60°, 90°, respect the longitudinal...

Previous research has proven that the Poly (2,6-dimethyl-1, 4-phenylene oxide) (PPO) dosimeter is capable of receiving both in-air and underwater UV exposures that are significantly greater than those of the more commonly used polysulphone dosimeter, within a range of accuracy close to what would be expected of dosimetric measurements made in-air provided that the necessary calibrations are com...

The present work is aimed at investigating the mechanical and in vitro biological properties of polyphenylene ether ether sulfone (PPEES)/nanohydroxyapatite (nHA) composite fibers. Electrospinning was used to prepare nanofiber composite mats of PPEES/nHA with different weight percentages of the inorganic filler, nHA. The fabricated composites were characterized using Fourier transform infrared ...
