Abstract
The paper presents the results of thermogravimetric/differential scanning calorimetry investigation of hybrid thermoset CFRPs modified by the addition of single-wall carbon nanotubes and milled carbon fibers. Specimens were tested using NETZSCH STA 409 PC/PG with the following parameters: heating from ambient temperature to 873 K with a rate of 15 K/min; Ar flow rate of 50 ml/min. The content of the carbon filler in CFRP was varied allowing to establish some regularities in thermal and physical properties.
Highlights
Composite materials are applied in many fields such as aerospace, marine, and mechanical engineering
It has been shown that the absorbed impact and shear punch energies in the punch tests are higher for composite filled with multi-walled carbon nanotubes (MWCNTs) by almost 21.3% which is connected with increased interlaminar fracture toughness, damping, and the alleviated crushing/buckling strength of the fibers
In terms of the Carbon fiber reinforced polymers (CFRPs) impact performance, the compressive strength of nanomodified composites was improved for all energy levels with the incorporation of 1.5 wt.% MWCNTs compared to the reference material
