Abstract
The aim of this research is to prepare a series of UHMWPE fiber (Ultra-high molecular weight polyethylene fiber) reinforced PU (Polyurethane) modified DGEBA (Epoxy resin) composites composed of the matrices based on PU and Epoxy resin with the reinforcement by neat, plasma treated and chemical agent modified UHMWPE fibers. The UHMWPE fiber/PU-crosslinked DGEBA composites and the UHMWPE fiber/PU/DGEBA grafted-IPNs composites were manufactured by filament winding and hot-press molding and cutting to various testing specimens with hydraulic power cutting machine. The characterization (FTIR and ATR-FTIR), thermal properties (Glassy- transition temperature and Heat-degrading temperature), mechanical properties (Tensile strength, Izod and Falling weight impact strength, Bending strength, Shear strength and bullet-proof testing) and morphology (Fracture surface and wet-out property) of the matrices and composites were investigated. The weathering properties and durable of the two kinds fiber reinforced composites were characterized via light-exposure apparatus (Xenon-arc type) and the standard practice for performing outdoor accelerated weathering tests. There are four basic parts of this research:
1. Research of the PU modified DGEBA matrix.
2. Research of the surface modification of UHMWPE fiber.
3. Research of the UHMWPE fiber reinforced PU/DGEBA composite.
4. Weathering effect of the UHMWPE fiber reinforced PU/DGEBA composites.
