Textile composites are the materials in which the composition and internal structure is changed under controlled conditions so as to match their performance to the most demanding structural or non-structural roles. Textile reinforcement structure can be made of fibers, yarns or fabrics (woven, braided, knitted or non wovens) and are generally flexible. The application of traditional textile tec...

This article features a large statistical database on the tensile properties of natural fibre reinforced composite laminates. The data presented here corresponds to a comprehensive experimental testing program of several composite systems including: different material constituents (epoxy and vinyl ester resins; flax, jute and carbon fibres), different fibre configurations (short-fibre mats, uni...

Poor wetting leads to underperforming composite properties and has been a major obstacle in implementing low cost carbon fibers in SMC parts. The objective of this project is to solve the technical challenge of poor carbon fiber wet-through during Sheet Molding Composite (SMC) process. Continental Structural Plastics (CSP) partnered with ORNL to develop a new sizing technique called Point Sizin...

According to the high demand of fiberglass/polyester composites in marine applications, this paper has studied the properties of these composites. It has also been shown that isophthalic polyester has better properties than orthophthalic polyester, in marine applications. This paper has also investigated the vinyl ester and phenolic resin stability especially in the sea water and has shown that...

The paper aims to present the experimental data retrieved after ultrasonic non-destructive testing on metallic particle reinforced polymeric composite materials. The particles’ size (μm), volume fraction as well as the matrix material (different types of polymeric materials – e.g. epoxy, vinyl epoxy, etc.) has their influence on the overall elastic characteristics of the composite material. On ...
