Abstract：High modulus glassfiber was introducedandthe major chemical composition factors toinfluence modulus，and themechanismof metallicoxides intheglassformulationisexplainedinthepaper.Formulationsofhighmodulusgla fiber wascompared withE-CRglassfiber.Thedevelopment historyof highmodulus glassfibers isreviewed，andcurrentdevelopmentstatus andtrendof high modulus glassfiberare introducedbyanalyzing thelatest patents inthe glass fiber industry. Windturbine blades are the majorappicationmarketforhighmodulusglass.Itis necessarytoimprovespecificmodulus and alsofocus onrecycle solutionsof high modulus glass fiber.Inorderto expand the applications of high modulus glas fibers，reducing cost and adding functionality are necessary work to be driven.

1引言

彈性模量（以下簡稱“模量”）是玻璃纖維和復(fù)合材料設(shè)計中的重要參數(shù)之一，表征了玻璃纖維抵抗變形的能力，是復(fù)合材料剛度的主要影響因素。（剩余7874字）
