Analysis of characteristics of composite materials built on ABS cores prepared by additive manufacturing
Abstract
Additive manufacturing represents an alternative that offers great
advantages in small-scale production, high level of customization
and ease of building complex geometries. However, rapid
prototyping parts present mechanical limitations that prevent their
use in applications that require greater resistance.
In the present work an experimental analysis was carried out
where the processes of Resin Infusion and Hand Lay-Up were
compared, performing tests with specimens constructed according
to the ASTM D790-17 standard, for laminated material of carbon
fiber with plastic nuclei by prototyping fast and tested with two
orientations of fibers “3k”, (-45º +45º and 0º 90º).
The tests and the statistical analysis of the data were made based
on a factorial design, generating results that offer acceptable
levels of stiffness and deflection without causing delamination
failures, obtaining a combination that allows the manufacture
of a piece without the need for a mold. The material constructed
by Hand Lay-Up offered the best performance, by not failing by
delamination
