Matrix Modification of Carbon Fiber Reinforced Composites with Hybrid Resin System

Abstract

The most important property required for any structural composite material is high strength to weight ratio and corrosion resistance. To improve the interfacial addition between carbon fiber and epoxy resin, the epoxy matrix has been modified with hybrid resin. The unidirectional carbon/epoxy composites were prepared with different weight proportions of two resins (hybrid resin) with parts by weight(PBW). In this paper unidirectional carbon fiber T700 used as reinforcement and hybrid resin used as matrix for preparing the Uni-Directional(UD) laminate and Naval Ordnance laboratories(NOL) ring specimens. These specimens are prepared with filament winding technique, specimens were tested as per ASTM standards and test was conducted on Instron 4505 with 100KN capacity. From the test results it has been observed that the tensile strength measured by NOL ring specimens are more trustable than the results obtained with unidirectional(UD) test specimens. NOL ring test data is useful for making composite pressure vessels for aerospace applications.

Investigation of Thermomechanical Analysis of Carbon/Epoxy Composite for Spacecraft Structure Material

“…Several studies have studied the mechanical properties of Araldite LY-5052 composites (Khan et al 2021;Tilak et al 2021;VenkateshwarReddy et al 2020). According to the VenkateshwarReddy study, a composite of LY5052 and carbon fiber T700 can withstand 1500 MPa in UD laminates and 1900 MPa in ring specimens.…”
