The in-plane thermo-elastic behaviour of woven fabric reinforced composites is analysed using a combination of published micromechanics and finite element techniques. The repetitive unit of an arbitrary woven fabric composite is divided into elements of which the thermo-elastic properties are determined using micromechanics. The properties of the repetitive unit are obtained using the finite el...

A soft lithographic method is described for casting functional thermoplastic devices with microscale features without the need for specialized tools or equipment. In the thermoplastic soft lithography process, termed solvent casting, low temperature supersaturated solutions of thermoplastic are poured over solvent permeable PDMS molds which allow omnidirectional solvent removal as they template...

Abstract Thermoplastic composite pipes (TCP) are a form of fibre reinforced thermoplastic that have proven benefits such as being lightweight and non-corrosive. However, during manufacturing, certain defects induced because parameters which eventually affect TCP performance in-service. Current manufacturing techniques challenged with on-the-spot detection the pipe is regularly monitored. When d...

Thermoplastic-based polymers are gathering importance in several engineering fields like electrical, electronic, automotive, aerospace, and structural. The additions of secondary phase reinforcements such as natural synthetic fibre improve thermoplastic-based polymer’s properties. thermoplastic combinations found to have low mechanical strength incompatibility need special treatment for synthes...

This paper describes an optimization procedure to design thermoplastic composite panels under axial compressive load conditions. Minimum weight is the goal. The panel design is subject to buckling constraints. The presence of the bending-twisting coupling and of particular boundary conditions does not allow an analytical solution for the critical buckling load. Surrogate models are used to appr...

PEEK is a high strength engineering thermoplastic that suffers from a high friction coefficient and a friction induced wear mode. Past studies with 0 m PEEK and PTFE powders resulted in composite solid lubricant that (at the optimal composition) had a wear rate of k= 2× 10−9 mm3/Nm ith a friction coefficient of μ= 0.12. A compositional grading of PEEK and PTFE is implemented in this study to cr...

many materials have been introduced for apexification each having their own advantages and disadvantages. this case report aims to present a new method of apexification using a combination of deproteinized bovine bone mineral (dbbm) and enamel matrix derivative (emd). after irrigating the canal of the maxillary right canine with 2.5 % sodium hypochlorite, a mixture of bio-oss and emd was packed...

This article is devoted to developing composite tribotechnical materials based on thermoplastic matrices for designs of autotractor units optimized service life, safety, and ergonomics. Also, the characteristics, parameters, application obtained are given.

An experimental investigation was conducted to determine the application of die sinker electrical discharge machining (EDM) as it applies to a hybrid titanium thermoplastic composite laminate material. Holes were drilled using a die sinker EDM. The effects of peak current, pulse time, and percent on-time on machinability of hybrid titanium composite material were evaluated in terms of material ...

Recently, interest in composite manufacturing has shifted towards the use of natural fibres as reinforcement because of their environmental benefits. The use of a biodegradable matrix is worth considering since this would result in a completely biodegradable composite. In order to assess the most suitable matrix polymer, one must know the properties of the available polymers. Since data tend to...
