The present paper is focused on evaluating the mechanical characterization of dicyclopentadiene (DCPD) and 5-ethylidene-2-norbornene (ENB) healing systems synthetized by in-situ polymerisation. Both healing systems were embedded in glass fibre reinforced polymer (GFRP) composite and subjected to three-point bending test regime. Microstructural and FT-IR analysis showed the formation of microcapsules and a successful integration in the composite material. To observe the influence of temperature variation, some specimens were exposed to thermal cycling (-20oC to +100oC) for 12 hours and tested in the same conditions. It was observed that the addition of microcapsules in the composite material decreased its mechanical properties by 8% and 10% for DCPD system and ENB system respectively. Thermal cycling suggested a drop of 24% on bending strength for DCPD system and 17% for ENB. Resting after 24 hours showed a healing recovery of 74% for DCPD healing system and of 97% for ENB system.

The main aim of this work is the mechanical characterization of a composite material resulting from the combination of three by-products coming from industry, namely, flue gas desulfurization (FGD) gypsum, granulated cork and textile fibers from tire recycling. The material is considered as a green material as the raw material are considered by-products and it is intended to be used as a building material for non-structural purposes in civil engineering construction. The mechanical characterization includes uniaxial compressive tests and bending tests for characterization of the fracture behavior. Additionally, ultrasonic pulse velocity is measured to evaluate its variation with time of curing.

The development of green composites to obtain scientific, technological and industrial application benefits, and evaluate different mechanical properties of those materials; as well as the great growth and the global market demand being considered as lightly and low manufacture cost materials, that has mechanical and physical properties equal or higher that will replace the materials that are traditionally seen in industry. Applying an analysis based in the experiments design (DOE) plus experimental essays, a mechanical characterization of composite material latex reinforced with short cabuya fiber was performed with random orientation and volumetric fractions of 20% latex - 80% cabuya fiber, 30% latex-70% cabuya fiber, 45% latex – 55% cabuya fiber; for the different combinations. Of the essays that were performed it was determined the test tubes that show better results in its mechanical properties through the UNE Norm (Tensil UNE - ISO 37, Compression UNE - ISO 7743, Strength UNE - ISO 48). With the analysis developed by the statistical methodology based on the complete general factorial design and the desirability function it was able to determine the best mechanical characteristics of the composite material that will be used, was the composite formed by fiber with 1 centimeter of length and a volumetric fraction of 20% Latex – 80% Cabuya.

AbstractIn this work the synthesis and mechanical characterization of a polymer matrix composite is reported. An epoxy resin is used as matrix with addition of starch and coconut fibers as reinforcement. Vickers hardness and impact tests are used for mechanical characterization. Starch is used to promote degradability of the polymer matrix with clear benefits for the environment. Natural fibers have been used for reinforcing the composite materials. Natural fibers have several advantages such as price, low density and relatively high mechanical properties, they are also biodegradable and non abrasive In this investigation, the composite material samples are fabricated with epoxy resin, 5, 10, 15 wt % of starch and 5, 10 wt % of coconut fibers with the help of silicon molds which have the dimensions and geometry according to ASTM Standards for make Impact and Vickers hardness tests. The obtained results show that increases in the amount of coconut fibers cause an enhancement of the mechanical properties of the material, due to a good adhesion between the polymeric matrix and the natural fibers.
