“…PE production via fusion spinning is cheaper, faster, more energy-saving and more environmentally friendly. PE has a higher carbon content and carbonation rate in addition to its congruence nature [ 11 , 13 , 14 ]. Its inherent defects make MPCF brittle, and that makes the spinning of these fibres difficult [ 3 , 4 ].…”

Manufacturing Pitch and Polyethylene Blends-Based Fibres as Potential Carbon Fibre Precursors

The advantage of mesophase pitch-based carbon fibres is their high modulus, but pitch-based carbon fibres and precursors are very brittle. This paper reports the development of a unique manufacturing method using a blend of pitch and linear low-density polyethylene (LLDPE) from which it is possible to obtain precursors that are less brittle than neat pitch fibres. This study reports on the structure and properties of pitch and LLDPE blend precursors with LLDPE content ranging from 5 wt% to 20 wt%. Fibre microstructure was determined using scanning electron microscopy (SEM), which showed a two-phase region having distinct pitch fibre and LLDPE regions. Tensile testing of neat pitch fibres showed low strain to failure (brittle), but as the percentage of LLDPE was increased, the strain to failure and tensile strength both increased by a factor of more than 7. DSC characterisation of the melting/crystallization behaviour of LLDPE showed melting occurred around 120 °C to 124 °C, with crystallization between 99 °C and 103 °C. TGA measurements showed that for 5 wt%, 10 wt% LLDPE thermal stability was excellent to 800 °C. Blend pitch/LLDPE carbon fibres showed reduced brittleness combined with excellent thermal stability, and thus are a candidate as a potential precursor for pitch-based carbon fibre manufacturing.

“…Pitch is an attractive material which can be widely used for fabricating anticorrosion membranes due to its stable chemical structure [12,13]. Among various kinds of pitches, isotropic pitch with suitable softening point can be used to prepare electrospun fibers [14,15]. Moreover, effectively choosing suitable structure and carefully controlling different material effects will maximize the acidproof and breathable performance [16,17].…”

To develop a series of novel acidproof and breathable fabric, electrospun fluorinated polyurethane/polyurethane and pitch nanofibers were directly deposited on polyester/cotton blended fabric. The layered and interpenetrated structured membranes were built to study the effects of different structures on the acidproof and breathable performances. The acidproof and breathable mechanism of different structured composite fabrics had been evaluated via emission scanning electron microscope, X-ray photoelectron spectroscopy, contact angle, porosity, pore size, comfort and mechanical test, respectively. The results showed that the layered structured composite fabric had advantages in acidproof property, i.e. the acid (H2SO4, 80%) contact angle was 130° due to the low surface energy caused by the high fluorine content (36.96%). Meanwhile, such structured composite fabric provided double protection, which made the acid-resistance pressure to reach a high value of 1050 Pa, while the interpenetrated structured composite fabric showed superior comfort and mechanical properties. Due to the high porosity (88.01%), the water vapor transport rate and air permeability were 7554.14 g/m2·24h and 46.33 mm/s, respectively. Due to the relative slip of fluorinated polyurethane/polyurethane fibers was restricted, the tensile strength and bursting strength of interpenetrated one was 1315 N and 795 N, which were higher than layered one.

In this work, we studied the effects of electrochemical oxidation treatments of carbon fibers (CFs) on interfacial adhesion between CF and epoxy resin with various current densities. The surface morphologies and properties of the CFs before and after electrochemical-oxidation-treatment were characterized using field emission scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, and single-fiber contact angle. The mechanical interfacial shear strength of the CFs/ epoxy matrix composites was investigated by using a micro-bond method. From the results, electrochemical oxidation treatment introduced oxygen functional groups and increased roughness on the fiber surface. The mechanical interfacial adhesion strength also showed higher values than that of an untreated CF-reinforced composite.
