Assessment of Matrix Cracking and Fiber Breakage in Hybrid Composite Materials.
Abstract: Hybrid composite materials, combining two or more distinct fiber or matrix constituents, have emerged as advanced structural solutions for aerospace, automotive, marine, and civil engineering applications. However, their complex microstructure makes them susceptible to multiple interacting damage mechanisms, particularly matrix cracking and fiber breakage. This study provides a comprehensive assessment of these damage modes, emphasizing their initiation, evolution, and combined effects on the mechanical integrity of hybrid composites. Matrix cracking …

Creep Analysis Characterization and Study of Biodegradation Effect on Compression Molded LDPE/Cellulose Composites
Abstract: AbstractSynthetic polymers are important industrial materials, but their everyday use is hazardous to the environment. The solution to this seems to lie in modification of their structure through blending with biopolymers. Low density polyethylene (LDPE) and Cellulose were used in sample preparation for research in this work. LDPE/starch composites have undesirable properties and so there was need to explore LDPE/cellulose composites and evaluate their susceptibility to primary biodegradation. Compression molded …
