Application of Glass Fiber Reinforced Composite Materials in Construction Engineering

Abstract

<jats:p>Glass fiber reinforced cement (GRC) is a new type of composite material formed by using alkali-resistant glass fiber as a reinforcing material and cement paste or cement mortar as a matrix. GRC is widely used in construction engineering. However, the durability of GRC is still a major problem in engineering applications, especially GRC materials have been in the hot and humid building engineering environment for a long time. The alkaline environment of the cement matrix will cause serious erosion of the glass fiber, and Will significantly reduce the mechanical properties such as flexural strength and toughness of GRC. In this paper, ordinary Portland cement is mixed with active mineral admixtures such as fly ash and silica fume to reduce the alkaline environment of GRC matrix, and to delay the erosion rate of glass fiber and increase the flexural strength and compressive strength of GRC; At the same time, the effects of different hot and humid building engineering environments on the mechanical properties of GRC were studied.</jats:p>

Effects of the molding process on properties of bamboo fiber/epoxy resin composites

“…Over the past half century, as an emerging material, composites have made great progress. Artificial fibers, such as carbon fiber and glass fiber, have been widely used in aerospace, transportation, wind power, and other fields (Chen and Ueharo 2020;Zhang et al 2020a). However, due to the environmental pollution of these materials, people have begun to use green natural fiber as the reinforcement of composites (Liu et al 2012;Depuydt et al 2019;Zhang et al 2020b).…”
