“…These results agree with the studies developed by Reis et al [3] where, for example, the addition of clays promoted maximum loads around 16.1% highest than occurred in Kevlar with pure epoxy resin. For Gustin et al [17] the differences observed in maximum forces results in the different failure modes, because each sample type has different tensile and shear properties. In terms of displacement, sandwiches manufactured with pure resin presented values about 17.0% higher.…”

ABSTRACT. The benefits of resins nano-enhanced on the impact response of sandwich composites made by fiber glass/epoxy skins and balsa wood core were studied. Afterwards, the influence of the core's discontinuity was analyzed in terms of impact strength. For better dispersion and interface adhesion matrix/clay nanoclays were previously subjected to a silane treatment appropriate to the epoxy resin. Resins enhanced by nanoclays promote higher maximum impact loads, lower displacements and the best performance in terms of elastic recuperation. The core's discontinuity decreases the impact strength, but the resin enhanced by nanoclays promotes significant benefits.

Modelo analítico de impacto em material composto aplicado ao projeto de capacetesIn this work, the energy and stress necessaries to cause permanent damage to a small-scale helmet surface made by composite materials have been investigated. The helmets made by lamination of epoxy resin with glass, Kevlar, carbon and jute fibers were submitted to an impact test based on the Snell M2005 testing procedure. The experimental results were paired up with the predicted values by the mathematical model. From the tendency observed on the result data, the material behaviour can be predicted successfully by the proposed model at the tested conditions.

“…Four factors were selected for evaluation, including moulding pressure (1,3,5 [MPa]), holding times at maximum temperature (0,30,60[s]), materials (carbon fibre, aramid plain fabric (twaron ® ), aramid plain fabric (technora ® )) and stacking sequence (A:X/CF/CF/CF/CF/X, B:CF/CF/X/X/CF/CF, C:CF/X/CF/ CF/X/CF, X is the material selected from three types). All factors were set to three levels.…”

“…To improve the impact resistance of CFRP, hybrid composites of Aramid Fibre Reinforced Plastics (AFRP) with Carbon Fibre Reinforced Plastics based on thermosetting resin have been studied [4,5]. However, there are problems in that recycling efficiency and productivity are low in the case of thermosetting resin.…”

Carbon Fibre Reinforced Plastics (CFRP) can offer a great deal of automobile weight saving. For automotive applications, however, they are not used well due to their low energy absorption and long production cycle time. Hybrid composite laminates of Carbon Fibre Reinforced Plastics/Aramid Fibre Reinforced Plastics (CFRP/AFRP), based on thermosetting resin, have a high strength to weight ratio and high energy absorption capacity. When CFRP/AFRP hybrid composite laminates will be used for the mass-produced car, it is necessary to consider the recycling efficiency and productivity. Therefore, it is preferable to use thermoplastics resin.The high-speed compression moulding method using an electromagnetic induction heating system has a big advantage for the moulding of continuous fibre reinforced thermoplastic composites, because this thermoforming technique could reduce the production cycle time drastically. In this study, a Carbon Fibre/Aramid Fibre Reinforced Thermoplastics hybrid composite (CFRTP/ AFRTP) was manufactured by the high-speed compression moulding method using an electromagnetic induction heating system, and the optimum moulding condition and mechanical properties of CFRTP/AFRTP hybrid composites were investigated.An optimum moulding condition was sought by using the design of experiments method. The factors used in this study were moulding pressure, maximum temperature holding time, materials and stacking sequences. hybrid composite that has CFRTP outermost layers has a moulding pressure of 4 MPa and holding time of 90 seconds.
