Abstract In this work, a novel method for more sustainable recycling and cost-efficient manufacturing technique of thermoplastic composite materials is proposed to recover reprocess waste end-of-life in aerospace industry. For the carbon fibre reinforced thermoplastics, an innovative scrapping process based on mechanical cutting has been developed properties obtained scrap recycled panel have a...

The aim of this article is to test the properties of foundry moulding sands with a new bicomponent organic binder. The new binder is the composition of phenol-furfuryl resin, commonly used in foundry practice and biodegradable material – polycaprolactone. The paper presents the research of strength properties, thermal destruction and thermal deformation of moulding sands with a new bicomponent ...

Abstract A nondestructive microwave testing method to control the green compression strength and moisture content was proposed demonstrated. There are various moulding sands, both qualitative (bentonite type) quantitative water content), prepared. The permittivity measurements were performed by cavity perturbation technique (CPT) at 2.45 GHz. Relative complex of bentonite bonded sands is propor...

In today’s competitive market many consumer products are designed with complex curved shapes to meet customers’ demands for styling and ergonomics. These styled products are commonly manufactured using moulding processes because they can produce a wide range of freeform shapes at relatively low cost. However, although injection moulding and metal casting allow a great deal of design freedom the...

Introduction. In Sub-Saharan Africa, excessive foetal head moulding is commonly associated with cephalopelvic disproportion and obstructed labour. This study set out to determine the associations of maternal pelvis height and maternal height with intrapartum foetal head moulding. Methods. This was a multisite secondary analysis of maternal birth records of mothers with singleton pregnancies end...

in many processes polymeric foams can be produced by using chemical or physical blowing agents. in this work for polyethylene foam production, the chemical blowing agents and compression moulding process were employed. at first, by using dsc diagram of two polyethylene grades, a suitable polyethylene grade was selected for foam production and then we discuss about blowing agent critical percent...

Graphene and its derivatives have excellent properties such as high surface area, thermal, mechanical strength, this fact made the researchers promote them possible filler material for fiber-matrix composite. The current research deals with validation on effect of graphene oxide boron nitride over thermal stability epoxy glass fiber polymer matrix objective experimental investigation is to deve...

During the placement of a mould for a hearing aid by a hearing aid dispenser, moulding MATERIALS entered the middle ear through preexisting perforations in the tympanic membrane. Middle ear foreign bodies are common otorhinolaryngological emergencies and must be removed to avoid complications. Surgical removal of the moulding MATERIALS by tympanotomy was necessary. Here, we report a case of a m...
