Notes:
Dilute polyolefin solutions, respectively based on EPDM and UHMWPE, were reacted with functionalized silanes to prepare coatings for glass fibers. These were found to provide adequate bonding characteristics for both glass and epoxy resin (bisphenol type). Unidirectional composites containing fiber matrix interlayers, using fibers coated with the aforementioned functionalized polyolefins, were found to exhibit much larger tanδ values over the temperature range of 60 to +60°C and greater ductility in flexural tests, albeit at the expense of a reduction in failure stresses. The UHMWPE coatings produced a multiple step fracture mechanism, which was deemed to provide a more efficient crack stopping mechanism than equivalent EPDM coated fibers. © 1993 John Wiley & Sons, Inc.
