摘要：

The optical fiber preform waste, an industrial by-product, was successively dried, crushed and grinded to produce fine particles, and then which are modified with coupling agents KH-570 and A-151 respectively to prepare KH-570/SiO2 and A-151/SiO2. Further, the prepared two powders were blended respectively with epoxy resin (EP) to prepare EP based composites. The results of hydrophobicity test, FT-IR and SEM show that the two coupling agents present significant modification effect on the waste particles, however the modification effect of A-151 is better. The overall tensile properties of the composites can be ranked as the following order: A-151/SiO2/EP>KH-570/SiO2/EP> unmodified powder/EP, and the tensile properties are the best when the powder mass fraction was 20%. The maximum tensile strength of the above three particles modified EPs is 49.37 MPa, 45.57 MPa, and 44.36 MPa, which are 19.9%, 10.7% and 7.8% higher than that of the plain EP, respectively. Correspondingly the maximum elongations at break of the three composites are 0.92%, 0.82% and 0.46% higher than that of the plain EP, respectively. Besides the composite material prepared by filling the powder with good modification effect show better heat resistance performance. © All right reserved.
