Resumo
The polymer composites provide physicochemical and mechanical properties which in
many cases have advantages over structures made of steel and aluminum. Additionally, with the
evolution of demand for new and challenging applications, manufacturing techniques are increasingly
moving to the use of methods and equipments that man dependence is increasingly reduced to ensure
quality and repeatability of manufactured material. Examples of this gradual development are the fiber
placement (FP) and tape laying (TL) processes in addition to the already established BMC, SMC,
RTM, filament winding and infusion processes. Considering, however, geometric shapes as well as
amount and orientation of fiber, few of them can meet these requirements satisfactorily. Textile
preforms manufacturing techniques allow to lay-up the desired amount of fiber in any position as well
as guide them in the directions according to design, also allowing to create different geometric shapes
and local reinforcement. In the present study unidirectional high strength carbon fiber preforms were
manufactured by the Tailored Fiber Placement (TFP) process using nonwoven fabric substrates.
Composite panels were manufactured by infusion and the geometry specimens followed the
dimensions given by ASTM D-3039. Results of tensile test specimens in the longitudinal direction
exhibited a strength of 2285 MPa, Young modulus of 137 GPa and strain around 1.47% for panels
with 54% fiber ratio. In the transverse direction the results were respectively 37 MPa, 5 GPa and 0.60.
