This paper presents a study of the folding of a new self-powered, self-latching tube hinge for deployable structures. This hinge is made by cutting three parallel slots in a thinwalled carbon fibre reinforced plastic (CFRP) tube, thus leaving three tape springs connecting the two ends of the tube.

One of the important features of the racing car is the power to weight ratio, and to this end, weight has been considerably reduced by the use of carbon fibre in the modern Formula One car. The weight saving obtained from carbon fibre components is utilised by the strategic placement of ballast (since there is a minimum weight limit set by the racing authority, the FIA), ordinarily as low as po...

Every Seifert Fibre Group is the lift of a Fuchsian group to the universal covering group of PSL (2,R). From this, we work out a form of presentation for such a group. With the calculation of the Euler number, we can establish the presentation of the derived group of a Seifert Fibre Group

Focal destruction of nerve-fibre bundles is one of the pathological common denominators of diseases involving the optic nerve, the optic papilla, or the superficial layer of the retina. Since Bjerrum (i 89 I) and Ronne ( g909, 19 I 3) first identified arcuate defects in the visual field as the perimetric correlates of defects in arcuate nerve fibres of the retina, quantitative perimetric studie...

The options for the fibre reinforcement of polymer matrix composites cover a range from short-fibre chopped strand mat, through woven fabric to unidirectional pre-impregnated (prepreg) reinforcements. The modelling of such materials may be simplified by assumptions such as perfect regular packing of fibres and the total absence of fibre waviness. However, these and other features such as the cr...

the aim of this study was to determine the effect of age on fiber characteristics of one-humped female camels of semnan province. 50 grams of wool samples from the left midside area were randomly collected from 28 camels of three different age groups: young, adult and old and fibre characteristics were measured. statistical model used for this research was completely randomized design (crd). an...

The translaminar fracture toughness is a key property that governs the damage tolerance and notch sensitivity of fibre-reinforced composites. Compact tension tests were performed to investigate composites reinforced with three types high-performance polymer fibres: polyarylate (PAR), polybenzobisoxazole (PBO) aramid fibre. A carbon fibre composite was used as reference system. propagation tough...

High aspect ratio carbon nanotubes are ideal candidates to improve the resolution and lifetime of atomic force microscopy (AFM) probes. Here, we present simple methods for the preparation of carbon nanotube modified AFM probes utilising solvent evaporation or dielectrophoresis. Scanning electron microscopy (SEM) of the modified probes shows that the carbon nanotubes attach to the probe apex as ...
