• Abstract

  The national aeronautic industry has been employing composite structure materials in order to be competitive over the worldwide industry, besides the research to employ them in automotive industry. Composite materials have high mechanical strength and low specific mass thus delivering high performance of the vehicles of transportation. There is a growing trend towards the increase of the …

  CARBON FIBER PREPREG SCRAPS REUTILIZATION FROM THE PRODUCTION CYCLE - FEASIBILITY BY USING THERMAL PRESS AND IN-PLANE MECHANICAL PROPERTIES PREDICTION, AP.R

• Abstract

  The industries sector of renewable energy, automobile, and Aerospace have been investigating new materials with specific properties such as mechanical, in order to increase their efficiency. Laminate composites have attended these current demands by providing structures with low specific mass and high modulus when compared with isotropic materials. However, in the manufacturing process an…

  Composites from carbon fiber and thermoplastic matrix waste: influence of fiber discontinuity and matrix type on mechanical properties, BP.IC

• Abstract

  Due to an increasing demand for composite materials, especially in the aeronautic field, this research work will focus on finding an average attenuation range and a standard deviation of attenuation range in which it will enable us to qualify as a "good" standard quality based on a comparison with mechanical properties such as fracture toughness. The study will be based on a series of dat…

  Relationship of ultrasonic attenuation parameters signals with composite materials quality, BP.IC

• Abstract

  This project aims continuing the studies on crack propagation in composite materials, that was started at Technical University of Delft. Considering the contribution will be more relevant in the field of composite materials.During the first phase of DR, it was conducted a huge bibliographic review in the field of resin flow in porous media, in which the original project was conducted, and…

  Crack growth rate in 5HS carbon/epoxy composites manufactured by RTM: Relationship between axial loadings with pure modes of delamination I and II, BP.DR

(Only some records are available in English at this moment)

• Abstract

  Due to the increase use of laminated composite materials in aircraft structures, and considering that composites have a low damage tolerance, the monitoring of damages in composite structures is necessary. Considering it, this research project proposes to use acoustic signals (collected using the acoustic emission technique), originating from damage mechanisms, to characterize damage in l…

  Relationship of damage mechanisms of non-crimp composite with acoustic signal, BE.EP.IC

• Abstract

  This research project aiming at evaluating the effect of gate location on 5HS toughened carbon fiber/RTM6 epoxy resin by performing fatigue test in mode I loading and analyzing the crack growth behavior through this toughened fabric. The 500 mm length mold is separated by an inlet gate and a vent gate where a release tape will be placed within a preform in their respective locations along…
