Web3.1.1 Rubber modified polybenzoxazine Blending with elastomers such as rubber is a useful method for toughening thermosetting resins. During curing, the rubber segment can generally be precipitated from the matrix and form a two-phase structure, in which the rubber is dispersed in the continuous phase of the thermosetting resin as spherical WebSep 23, 2024 · In this work, carboxyl-terminated butadiene nitrile liquid rubber (CTBN) was used to toughen the boron nitride-epoxy hybrid system, and the effects of different contents of CTBN on the mechanical properties, thermal conductivity, glass transition temperature, thermal stability, and dielectric properties of the composites were investigated.
Modification of epoxy resin using reactive liquid (ATBN) rubber
WebJun 25, 2024 · Zhou et al. proposed a novel method for preparing CTBN /epoxy blend, in which an initiator was added to the liquid rubber-epoxy mixture to initiate the cross-linking reaction and then a curing agent was added to cure epoxy. The results showed that the impact strength of CTBN/epoxy blends was greatly improved without affecting the modulus. WebMay 20, 2024 · The toughening mechanisms induced by CTBN, such as rubber cavitation and matrix shear banding, contributed to the enhanced fracture toughness of the CTBN/epoxy cured with the amine-based agent. 馬 ジャスティファイ
