This paper aims to show, that the preforming process of parts made of Carbon Fiber Reiforced Thermoplastics (CFRTP) can be improved, when using several technologies like near-net shape cut-piece generation with forming simulation, automated cut-piece detection, robotic gripping and laydown of fabrics. Thereby the authors of this paper want to contribute to the increase of CFRTP applications in ...

The synthesis of proteins, polyesters, polysaccharides and polynucleotides can be adapted to produce new macromolecular materials. Proteins of designed sequence, and with specific chemical functions, conferred by the incorporation of unnatural amino acids, have been prepared in genetically engineered bacteria. Polyesters, useful as biodegradable thermoplastics, have been made in bacterial hosts...

The thermal properties and rheological behaviors of polystyrene (PS)-based thermoplastics bearing polyhedral oligosilsesquioxane (POSS) were investigated with variation of isobutyl (iBu)-POSS weight percentage. The incorporation of POSS-group significantly decreases the glass transition temperature and the rubbery plateau modulus. These findings are attributed to an influence of the nanometer-s...

Transfemoral sockets were originally constructed from wood or hard plastic laminates (Radcliffe, 1955). More recently, thermoplastics and acrylic resins with carbon fiber or other woven materials have been used (Ng, 2002). Although these materials achieve suitable load transmission between the residual limb and the prosthesis, their rigidity prevent the sockets from dynamically conforming to ch...

The mechanical recycling of solid plastic waste on a small-scale level can be accomplished with the correct approaches. Thermoplastics are types mostly considered for because their physical properties and ease reprocessing. This paper reviews reprocessing techniques selected thermoplastics (polyethylene terephthalate polyolefins), since they constitute significant proportion plastics used comme...
