In low-volume hypercar and luxury programmes, exposed carbon is often the customer-facing product. Scrap on a cosmetic outer ply is not a quiet quality-hold issue — it is a visible brand failure and a six-figure material write-off. That is the commercial context for SHD Composite Materials’ launch of MTC575, a cosmetic-grade carbon fibre prepreg announced in March 2026 and covered by CompositesWorld and SHD’s own channels.
SHD positions MTC575 as a highly engineered visual system for automotive, motorsport, luxury industrial design and high-end consumer products — explicitly calling out hypercar exteriors and luxury automotive interiors. Head of EU Sales Chris Henshaw described the aim as best-in-class visual response with the consistency premium manufacturers need. Design of the product involved format optimisation, a distinctive resin formulation and customer collaboration aimed at depth, clarity and refined surface appearance.
Process stack: surface ply plus structural backing
SHD’s technical documentation for MTC575 frames it as a toughened epoxy system for high visual quality, supplied on reinforcements optimised for surface-ply use. Critically, SHD recommends running MTC575 in conjunction with standard MTC275 as the backing ply to achieve the most consistent premium visual result — naming specific MTC275 fabric constructions as preferred partners. That is a procurement detail, not a lab footnote: cosmetic systems are often dual-material BOMs, and buyers who specify only the “pretty” ply without locking backing, resin batch windows and cure schedules invite variability across consecutive cars.
Typical applications listed by SHD centre on highly visual carbon components. Fibre volume fraction, cured ply thickness and density ranges are published on the TDS for the primary MTC575-C245T-HS-3K construction — useful anchors for process engineers comparing alternative cosmetic prepregs, but not a substitute for line trials on the actual tool and finish system (clear coat, polish, UV package) the OEM will ship.
Procurement and risk questions
- Is MTC575 single-sourced for a given programme, and what is SHD’s capacity / lead time for visual-grade rolls versus structural grades?
- Are backing plies (MTC275 or approved alternatives) dual-sourced with the same visual qualification matrix?
- What scrap/yield assumptions does the OEM use for exposed aero panels and interior visible CFRP — and who owns rework versus remake?
- How are batch-to-batch colour, weave clarity and void criteria defined in the quality agreement?
- Does the programme need flame-retardant cosmetic variants (SHD has separately discussed FR cosmetic grades) for interior or regulatory-driven parts?
Procurement takeaway
MTC575 is a reminder that raw-material risk in LVHV is not only structural CFRP and titanium fasteners. Cosmetic-grade prepreg sits at the intersection of CMF, composites process control and brand risk. Buyers should put visual systems on the same dual-source and qualification discipline as structural plies — and treat SHD’s surface-plus-backing guidance as part of the controlled process, not optional advice.
