Ceramic Matrix Composite Interlaminar Fracture Toughness (Mode I-II) Characterization

Volume 6: Ceramics; Controls, Diagnostics and Instrumentation; Education; Manufacturing Materials and Metallurgy; Honors and Awards, 2015
The objective of this effort is to develop and demonstrate innovative interlaminar Mode I and Mode II fracture toughness analysis and test methods for ceramic matrix composites (CMC). Currently, there are number of American Society for Testing and Materials (ASTM) test standards for CMC’s at both ambient and elevated temperatures, including ...

Mode I interlaminar fracture toughness of commingled carbon fibre/PEEK composites

Journal of Materials Science, 1993
Carbon fibre/poly (ether-ether-ketone) (PEEK) composites were fabricated from plain weave cloth using the commingled yarn of carbon fibres with PEEK filaments. The undirectional specimen was made from the warp of commingled yarn and the weft of PEEK yarn, while the two-dimensional specimen was made from commingled yarns both of the warp and the weft ...

Mode I interlaminar fracture toughness properties of advanced textile fibreglass composites

Composites Part A: Applied Science and Manufacturing, 1999
Abstract The Mode I interlaminar fracture toughness properties of vinyl ester-based composites reinforced with fibreglass manufactured by the advanced textile technologies of braiding, knitting, stitching and through-the-thickness weaving are assessed in comparison to a variety of traditional composites made from fibreglass such as unidirectional or ...

Mode I Interlaminar Fracture Toughness of Through-Thickness Reinforced Laminated Structures

Advanced Materials Research, 2011
The main objective of the study is to understand the mechanisms of the preform reinforcement (2D, stitched and 2.5D) in laminated composite materials. The study is focusing on the mode I interlaminar fracture toughness for glass/vinylester based composites.

Rate Effects on Mode I Interlaminar Fracture Toughness in Composite Materials

Journal of Composite Materials, 1987
The Double Cantilever Beam (DCB) test geometry was utilized to investigate the rate ef fects on Mode I interlaminar fracture toughness in graphite/PEEK and graphite/epoxy composites. The tests were performed over a range of crosshead speeds from 4.2 × 10-6 to 6.7 × 10 -1 m/s.
