Abstract

Abstract: In this paper, a kind of unidirectional quartz fiber reinforced bismaleic resin matrix (brand:QF210/5429) composite with low loss and high transmission was treated by damp heat aging. The moisture absorption change law of QF210/5429 composite was studied. The mechanical properties and electrical energy of the composite after damp heat treatment were studied, and the influence mechanism of damp heat treatment on the properties of the composite was analyzed. The results showed that the saturated moisture absorption rate of QF210/5429 composite is 0.6%. After saturated moisture absorption, the tensile strength and interlaminar shear strength of the composite are 1 450 MPa and 105 MPa respectively. Compared with the tensile strength and inter laminar shear strength of the composite without damp heat treatment, the inter laminar shear strength is reduced by 20.5% and 13.9% respectively. The bending and compression properties of the composite have no obvious change. After saturated moisture absorption, the dielectric constant of the composite is about 3.55, and the tangent value of dielectric loss is about 1.1×10^-2. Compared with the composites without damp heat treatment, the dielectric constant has no obvious change, but the tangent value of electrical loss increases by 120%.
