High-Specific-Strength Densified Superwood via Delignification and Hot-Pressing
Rejected
This concept did not clear the framework. The reasoning is published in full below.
What the assessment found
| Incumbent benchmark | 6061-T6 aluminum plate |
| Entry application | structural floor decking and sidewall paneling for heavy-duty commercial freight trailers |
| Measured advantage | 3.67x higher specific tensile strength (422.2 MPa cm³/g vs ~115 MPa cm³/g for 6061-T6 aluminum plate) |
| Time to first revenue | 24 months |
| Gross margin at parity | 43.7% |
| Startup CapEx | $1,250,000 |
| Payback from first sale | 29.7 months |
| Capital productivity | 1.3x |
| Regulatory risk | Moderate — qualification costs reported ($500,000 estimated) |
Why it failed
- Voided by: Capital and time to revenue, Economics undisclosed, Entry application mismatch, Form-factor / handling regression, Absence search missing
- Evidence rests on non-peer-reviewed sources
- Margin fails the operating-cost check
- payback_over
- capital_productivity_under
- Uncited safety claim
- Absence asserted, search unreported
Assessment
The proposal fails financial and operational gates with a $1.25M CapEx, 44% gross margin, and 24-month timeline to revenue. It also lacks a structured Market Absence Ledger and exhibits critical anisotropic and moisture failure modes in the entry application.
Also flagged
- Price parity asserted, not sourced
- runsheet_no_quantities
A rejection is not a claim that the science is wrong. It means the venture case did not survive: the comparator was not what the buyer actually buys, the comparison was not like-for-like, the advantage fell short of a step change, or the capital and time to first revenue were prohibitive.
