Using a polyester binder for the interlaminar toughening of glass/epoxy composite laminates [PDF]

, 2015
Bisphenol A based polyester is commonly used in the industry as a binder, or tackifier, to produce cost-saving preforms in Liquid Composite Moulding processes such as Vacuum Assisted Resin Transfer Moulding (VARTM). However, it is often reported that the

The influence of toughening-particles in CFRPs on low velocity impact damage resistance performance

, 2014
The role of particle-toughening for increasing impact damage resistance in carbon fibre reinforced polymer (CFRP) composites was investigated. Five carbon fibre reinforced systems consisting of four particle-toughened matrices and one system containing ...

Microscale Mapping of Fiber Strain and Damage in Composite Wrinkled Laminates Using Computed Tomography Assisted Wide‐Angle X‐Ray Scattering

Advanced Science, EarlyView.
This study combines full‐field tomography with diffraction mapping to quantify radial (ε002$\varepsilon _{002}$) and axial (ε100$\varepsilon _{100}$) lattice strain in wrinkled carbon‐fiber specimens for the first time. Radial microstrain gradients (−14.5 µεMPa$\varepsilon \mathrm{MPa}$−1) are found to signal damage‐prone zones ahead of failure, which ...

Graphene‐Skinned Alumina Fiber: Continuously Scalable Fabrication and Its Electrothermal Application in Fiber‐Reinforced Polymer Composites

Advanced Science, EarlyView.
Graphene‐skinned alumina fiber (GAF) is a new composite with graphene conformally grown on individual alumina fibers via chemical vapor deposition (CVD). GAF's dynamic, continuous and scalable production is achieved by using a home‐made roll‐to‐roll (RTR) CVD system featuring integrated degumming and growth chambers. GAF possesses tunable conductivity,

Effect of Designed 3D Reinforcement in Mitigating Machining Damage on CFRP Plates

Polymer Composites, EarlyView.
Effect of Edge Tufting on Surface Quality, Damage, and Mechanical Performance in CFRP Machining: A Comparative Topographical and Structural Analysis. ABSTRACT Composite materials made of carbon fiber‐reinforced epoxy (CFRP) are widely used in aerospace fields due to their high strength‐to‐weight ratio. However, due to low out‐of‐plane resistance, these

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres

Polymer Composites, EarlyView.
Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...

Cyclic Olefin Copolymer Interleaves for Thermally Mendable Carbon/Epoxy Laminates

Molecules, 2020
Thin cyclic olefin copolymer (COC) foils were used as intrinsic thermoplastic healing agents in carbon fiber (CF)-reinforced epoxy laminates. COC films were produced by hot pressing and were interleaved in the interlaminar regions between each EP/CF ...
