摘要
通过直立式浸胶制备环氧树脂(EP)涂覆E–玻璃纤维(E–GF)。直立式浸胶方式和聚醚醚酮(PEEK)挤胶辊的采用使得涂覆E–GF的含胶量、涂覆层均匀程度和拉伸载荷高于沉浸式浸胶和手工浸胶。研究表明,直立式浸胶过程中,稀释剂对样品的含胶量影响最大;胶液的温度对涂覆GF拉伸载荷的影响最大。扫描电子显微镜分析证明直立式浸胶的胶液层均匀,断口照片显示纤维产生平齐断裂,使得涂覆纤维的拉伸载荷提高。傅里叶红外光谱分析证实直立式、沉浸式和手工浸胶三种不同浸胶方式不影响树脂胶液的固化反应,含胶量和涂覆均匀度不同是导致涂覆E–GF拉伸性能存在差异的原因。
Up-right soaking glue technology was designed and utilized in this work to manufacture the E-glass fiber ( E^3F ) coated with epoxy resin ( EP ) .Due to the up-right soaking glue technology and the application of polyetheretherketone ( PEEK ) roll coater in the process, the gel content, the homogeneity of resin coating layer and the tensile load of the coated E-GF were better than those of the immersion soaking glue technology and the hand-by soaking glue technology.The research results illustrated that the diluent agent exerted a critical influence on gel content and the temperature of resin glue was essential for the tensile load of the coated E-GF respectively.The result of Scanning Electron Microscopy proved that the glue layer on the surface of E-GF was homogenous and the coated E^GF exhibited a level break under the tensile force, which improved the tensile load of the coated E-GF. Through the Fourier-Transfer Infrared investigation, the cross-polymerization of the epoxy resin was proved to be the same for the up-right, immersion and hand-by soaking glue technology.The variation of the gel content and the homogeneity of resin coating layer affected the tensile property of the coated E-GF.
