Ensaios de tração em compósitos com matriz biopolimérica

Abstract

Currently the use of composite materials have been subject of many studies thanks to them properties, characteristics and versatility, being holder of many advantages compared to materials already used in engineering; this kind of material is wildly used in many areas due its wide applicability, and thus able to supply the needs from the industrial sector covering up areas like medicine, such as the case of the polyurethane derived from mamona (Ricinus Communis) oil, focus of this estudy, because it is a biopolymer with a great potential applicability in bone prosthesesthis. Amidst all these advantages the material in question has the difficult balance between productivity and high performance as a problem, since it is dependent on the resin cure raising the costs of manufacturing process. Given these supportive and attractive information about the use of composite materials identify the need of proof on the mechanicals properties so that it can be possible to have a positive or not conclusion about the use of this type of material. Thus experimental tensile tests on standard samples were realized to acquire material properties for this type of solicitation, and compare this properties obtained theoretically.
