JiLin Tangu supplies carbon fibre reinforcements, prepregs and composite structures for application-led development. This overview connects the product portfolio with documented 200 g/m² fabric examples, manufacturing choices and the evidence needed for a qualified supply specification.

Spar cap defects rarely come from one cause. This guide walks through the three failures that dominate wind blade carbon laminate production lines — exotherm runaway and dry spots in thick infusion, surface cracking and fibre wrinkling in pultruded plank, and NDT acceptance plus repair decisions — with the process windows, tension settings and test data that keep a rejected part from becoming a scrapped blade.

VARTM wind blade spar caps fail on the interface before they fail on the fibre. This guide connects sizing chemistry to contact angle, permeability and interfacial shear strength, with measurable acceptance windows, wet-spun tow selection and inter-layer flow fabric data for thick laminates.

Published market research puts automotive carbon fiber composite parts at $5.231 billion in 2024, $5.739 billion in 2025 and $14.51 billion by 2035 — a 9.72% CAGR and more than 177% expansion. This guide breaks the forecast down by driver, segment, process and region, then maps each automotive part type to the fabric, prepreg or finished form that fits it.

Carbon-glass hybrid fabric combines carbon fiber and glass fiber in one reinforcement, usually as a 0/90 stitched construction, to balance stiffness and cost. This guide explains the structure (0 degree carbon, 0 degree glass, 90 degree carbon, 90 degree glass plus two edge stitch lines), the dimension scheme (600 mm between stitches, 620 mm roll width, 10 mm fringes), the many English names buyers use when searching, and how to choose between hybrid, all-carbon and all-glass fabrics.

Selecting a prepreg epoxy resin is a trade between working time and cycle time. This guide compares a standard 125 degrees C curing system with a fast-cure system and a medium-temperature appearance system, using measured viscosity-temperature curves, dynamic and isothermal DSC data, gel times from 100 to 150 degrees C, and DSC versus DMA glass transition results. It explains how to read those curves, how cure temperature sets the achievable Tg, and which process limitations decide the choice for tubes, automotive panels, and large vacuum-bagged structures.

Epoxy and polyurethane (PU) resin systems set very different limits on carbon fiber pultrusion. This guide compares the two chemistries on cure kinetics, wet-out, ILSS, fatigue and durability, explains how line speed moves from 0.5-0.8 m/min to 1.5-2.0 m/min with a 15-20% energy and conversion cost reduction, and shows why the carbon fiber sizing system decides which resin route is open to you.

Wet-spun and dry-spun carbon fiber differ in filament handle, resin wet-out and the applications they serve. This guide compares the two spinning routes on process, properties and selection so you can specify the right carbon fiber for prepreg, fabric or filament winding.

Carbon fiber makes longer, lighter offshore blades possible — and it also turns every blade into an electrical system. This engineering guide explains how carbon fiber conductivity changes lightning attachment, how to integrate carbon laminates with copper and aluminium mesh LPS, and how to design insulative barrier layers that stop galvanic corrosion at the carbon-glass and carbon-metal interfaces.

What is carbon fiber? This guide explains carbon fiber from first principles: PAN precursor, wet vs dry spinning, the manufacturing process from precursor to filament, key mechanical properties with real data, tow sizes and grades, applications across industries, and a comparison with steel, aluminum, and glass fiber. Includes 10 technical FAQs and practical supplier selection advice for engineers.
