| 摘要 | A method of attaching a composite member to a structure. The method including forming a laminate of fabric impregnated with resin; applying heat at a first temperature to the impregnated laminate; applying vacuum at a first pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate; positioning the degassed, impregnated laminate on a structure; and curing the degassed, impregnated laminate on the substrate by applying heat at a second temperature and by applying vacuum at a second pressure. | ||

| 主权项 | 1. A method of attaching a composite member to a structure, comprising: forming a laminate of fabric impregnated with resin; applying heat at a first temperature to the impregnated laminate; applying a partial vacuum at a first vacuum pressure to the impregnated laminate to degas the resin and form a degassed, impregnated laminate; positioning the degassed, impregnated laminate on a structure; and curing the degassed, impregnated laminate on the structure by applying heat at a second temperature and by applying vacuum at a second vacuum pressure, the second vacuum pressure greater than the first vacuum pressure, wherein only a same single vacuum enclosure is used when applying heat at the first temperature, when applying the partial vacuum at the first vacuum pressure, and when curing the degassed, impregnated laminate. | ||
