Abstract

PLACAS-CUBO DEL ROTOR DE HELICOPTERO, EN PARTICULAR, PLACAS-CUBO FORMADAS POR COMPOSICIONES DE MATRIZ EPOXI REFORZADA CON FIBRA.COMPRENDEN UNA MATRIZ DE RESINA DE EPOXI REFORZADA CON FIBRAS, LA CUAL ESTA FORMADA POR UNA SERIE DE CAPAS DE REFUERZO DE GRAFITO A BASE DE FIBRAS CONTINUAS DISPUESTAS EN UN PLANO ISOTROPICO Y DE REFUERZO DE VIDRIO A BASE DE UNA SERIE DE SEGMENTOS CON FIBRA DE VIDRIO ENROLLADA PERIFERICAMENTE ALREDEDOR DE UN EJE CENTRAL, Y EN UN PLANO SUSTANCIALMENTE PARALELO AL PLANO DE REFUERZO DE FIBRAS DE GRAFITO. LAS CAPAS DE REFUERZO DE GRAFITO Y DE VIDRIO ESTAN INTERCALADAS SIMETRICAMENTE, AL OBJETO DE OBTENER RESISTENCIA ALAGRIETAMIENTO, TOLERANCIA AL DETERIORO E INTEGRIDAD DETECTABLE.
