高硅氧玻纤布/酚醛树脂复合材料的制备及其在过滤网中的应用
Preparation and filter application of high silica- glass-fiber-cloth/phenolic resin composites
摘要
Abstract
Taking the water soluble phenolic-formadehyde risin as the basis ,impregnating high silica-glass-fiber-cloth ,high silica-glass-fiber-cloth/phenolic resin composites are obtained by high tempera-ture formed after the high temperature curing .The microstructure of composites was characterized by FT-IR and SEM ,and curing formation ,the thermal stability and mechanical properties were tested by TG and universal testing machine .The influence of the molar ratio of formaldehydes to phenol on the thermal properties of the composites was discussed .The tensile properties and hot metal filtration ex -periments were carried out for composites with the best thermal properties .The results show that the thermal residual rate of the composites at 900 ℃ increased firstly and then decreased with the increase of formaldehyde/phenol molar ratio .When the molar ratio of formaldehyde to phenol was 1.25 ,the thermal residual rate of composites reached the maximum ,77.38％ and its fracture strength was 89.6 MPa .Such above composites were then tested by hot metal filtration .The results indicate that they satisfy the requirement on molten iron casting .关键词
