The optimized design was successfully manufactured by winding the additively-manufactured internal structure by a carbon/epoxy composite. Preliminary numerical results confirm the potential of the method. 000022901 540__ $$aText je chráněný podle autorského zákona č. 121/2000 Sb. 000022901 653__ $$acarbon fiber composites, semidefinite programming, truss topology optimization, reinforcement design, additive manufacturing 000022901 7112_ $$aEngineering Mechanics 2018$$cSvratka, CZ$$d2018-05-14 / 2018-05-17$$gEM2018 000022901 720__ $$aTyburec, M.$$iet, al. 000022901 8560_ $$ffischerc@itam.cas.cz 000022901 8564_ $$s9853295$$uhttps://invenio.itam.cas.cz/record/22901/files/873.pdf$$yOriginal version of the author's contribution in proceedings, page , section SOL. 000022901 962__ $$r21225 000022901 980__ $$aPAPER
